Femoroacetabular impingement

Definition Early pathological contact between bony prominences of femur and acetabulum during hip motion due to a variety of morphological conditions leading to pain and chondrolabral damage predisposing the patient to early osteoarthritis of hip.


• First described in 2003 by Prof Reinhold Ganz from Bern Hip Group, Switzerland.

• Impingement may be intra-articular or extra-articular.

• Intra-articular impingement may be of 3 types

○ Cam

○ Pincer

○ Combined-86%

• Abnormal morphology and / or motion is required for clinically relevant impingement to occur.

• In addition a subluxating impingement also has been described by Leunig in 2001 in patients with shallow and dysplastic acetabulum.

Cam type impingement

• Loss of normal head neck offset is the underlying cause.

• The hump at the femoral head neck junction and the loss of normal concavity of the superior border of neck of femur is called pistol grip deformity.

• Anterior hump causes outside-in abrasion of labrum and cartilage in the anterosuperior part of acetabulum on flexion and internal rotation.

• Mismatch between femoral head and acetabulum leads to abutment of aspherical head and acetabulum rim leading to shear stresses which causes injury to the labrum and cartilage.

• Chondrolabral separation, cartilage delamination and chondral defects develop leading to osteoarthritis.

Pincer type impingement

• Acetabular overcoverage is the underlying cause.

• Overcoverage may be localized or generalized.

• Overcoverage may be due to increased acetabular depth, abnormal version of acetabulum or localized bone overgrowth.

• Leads to labral damage, ossification of labrum and cartilage damage over a circumferential narrow strip at the rim of acetabulum.

• Impingement may lead to subluxation of head in the opposite direction leading to contre-coup cartilage lesions.

Clinical assessment

• Young in their 20-40s.

• Presents with groin pain in the sitting position.

• Pain during or after sports activities

• Internal rotation and flexion are typically limited.

• Anterior impingement test- Groin pin on forced internal rotation and adduction in 90 degrees of  flexion.

• Posterior impingement test- Pain on hyperextension and external rotation of hip.

• Drehmann’s sign- Unavoidable passive external rotation on flexion (axis deviation) due to anterior impingement.


• Anteroposterior and lateral views of the pelvis with both hips are taken.

• Identify the abnormal morphology of acetabulum and femur.

• Identify labral and cartilage damage.

• Herniation pits or Pit’s pits are seen in FAI.

• In cam impingement, the characteristic chondrolabral damage is seen in the anterosuperior part of acetabulum.

• In pincer impingement chondrolabral damage is seen posteroinferiorly.

• Quantify the degree of osteoarthritic changes

○ As positioning for x-rays can alter the measurements first ensure proper positioning of x-rays.

○ Acetabular coverage- CE angle, Acetabular index, Extrusion index

○ Acetabular depth- Kohlers line

○ Acetabular version

   § Posterior wall sign- Posterior margin of acetabulum lies medial to the centre of femoral head.

   § Cross over sign- Posterior margin of acetabulum crosses the anterior margin and the inferior part of posterior margin lies medial to the anterior margin.

   § Ischial spine sign- Prominent ischial spine projecting medial to the pelvic brim is a sign of retroversion of acetabulum

  ○ Femoral head neck asphericity.

   § Alpha angle- Described by Notzli. <50 degrees. >55 degrees indicates loss of femoral head neck offset. Measured ideally on the radial slices taken along the axis of femoral neck. Angle between the axis of femoral head and neck and the line drawn between center of femoral head and the head neck junction.

   § Head neck offset less than 10mm.

  ○ Femoral neck shaft angle

• Varus and valgus deformity of proximal femur may also may contribute to the development of impingement.

• Torsional deformity especially of the acetabulum is an important cause of impingement.

• Conventional MRI with orthogonal slices cannot fully visualize the labral and chondral lesions of FAI.

• MR Arthrography with radial slices is the gold standard for assessment of FAI.

• Delayed Gadolinium-enhanced MRI of cartilage (dGEMRIC) allows quantitative assessment of chondrolabral damage.


• Depends on the age and activity profile of the patient.

• Asymptomatic individuals generally doesn’t need treatment.

• If significant osteoarthritic changes are present then total hip replacement is the treatment of choice.

• In the absence of OA changes; treatment depends on the type of impingement, location of impingement and degree of acetabular and femoral version.

• Aim of treatment in cam impingement is restoration of sphericity of the femoral head by reshaping the head neck junction.

• Cam impingement is treated by osteochondroplasty.

• Isolated anterosuperior cam impingement can be treated by arthroscopy.

• Cam impingement close to the site of entry of epiphyseal vessels, posterior cam and multiple pathologies need open treatment by safe surgical dislocation.

• Safe surgical hip dislocation is the gold standard in the treatment of FAI.

• Lateral approach through the Gibson interval between gluteus medius and gluteus maximus utilized.

• Z- capsulotomy with preservation of labrum, short external rotators, pyriformis and the medial circumflex artery.

• Anterior limb of capsulotomy is close to the femoral attachment of capsule and the superior limb is at the acetabular attachment of capsule.

• Aim of treatment in pincer impingement is to reduce acetabular overcoverage.

• Pincer impingement needs careful assessment of acetabular version.

• Severe retroversion of acetabulum needs periacetabular osteotomy to restore normal anteversion of acetabulum.

• If acetabular version is normal then pincer impingement is treated by rim trimming and labral reattachment.

Basics of radiation safety for the orthopaedic surgeons

Use of c-arm is now an essential part of orthopaedic practice.  Use of C-arm fluoroscope in orthopaedics has improved patient outcomes by improving precision in surgery and by reducing surgical trauma by permitting minimally invasive techniques.

 Radiation Physics


Within the x-ray source an electrically heated filament produces electrons. These electrons are accelerated by a high voltage towards an anode made of high atomic weight elements such as tungsten. When the high energy electrons hit the tungsten and gets decelerated a small number of x-ray photons are emitted and the rest is converted to heat. The number of electrons depends on the strength of the electric current in milliamperes (mA). The maximum kinetic energy of the electrons is expressed as kilovolts peak (kVp). Higher mA produces more x-ray photons and higher kVp produces higher energy x-ray photons with greater penetrability. Higher mA increases the brightness of the image. Higher kVp may reduce the contrast of the image.

As the beam leaves the x-ray tube the rays diverge leading to reduced radiation with increasing distance. As the relationship between radiation and distance is by inverse square law; even small increase in distance can reduce radiation by a large percentage.


Fate of x-ray within the human body

When x-rays are beamed towards the human body they may three outcomes depending on the tissue electron density, tissue thickness and the x-ray beam energy.

  1. Completely penetrate the body and emerge at the opposite end to be detected by the film or detector. (1% of the beam during fluoroscopy)
  2. Completely absorbed by the tissue.
  3. Scattered by the tissue.


After the discovery of xrays by Roentgen in 1895, its potential benefits in the medical field was immediately recognised but the identification of its deleterious effects took a longer time. Radioactivity was discovered in the same year by Becquerel and its usefulness in the treatment of malignancy was recognised early due to its deleterious effects. In the year 1900, Albers Schonberg advised reduced frequency of exposure, use of lead shielding, gap of more than 30 centimetres from source as safety measures when working with radiation. In 1928, roentgen was accepted as the quantitative measurement for radiation exposure. International X-ray and Radium Protection Committee was formed in 1928.  It was renamed later as International Commission on Radiological Protection (ICRP). Its aim is to advance the science of radiation protection. It has published several guidelines for radiation protection.



C-arm is an x-ray unit that allows alteration of angle and rotation of X-ray source and detector to permit imaging without changing the position of the patient. It was introduced in 1955. It is comprised of an X-ray generator and a image intensifier. The X-rays strike a fluorescent screen which glows according to the strength of the radiation. C-arms use caesium iodide for the fluorescent screen which converts the X-ray photons into photons in the visual spectrum by its luminescence property. A photocathode made of an antimony caesium compound situated beneath the fluorescent screen captures the glow and amplifies the luminance. In C-arms with flat panel detector the X-Rays are converted digitally into a visible spectrum.

Risks of ionizing radiation

Ionising radiation is potentially hazardous to the personnel and patient. Ionising radiation is classified as a carcinogen by the World Health Organisation. X-ray photons absorbed are a source of injury to the patient and the scattered rays is a potential source of injury to the personnel.

Risk of radiation injury is increased with higher doses and longer exposure times. The harmful effects may be for the individual or his descendants. They may be classified as somatic or genetic. Biological effects of radiation are classified into stochastic effects and deterministic effects. Stochastic effects may be malignancy or genetic defects. Stochastic effects like cancer and genetic defects can occur at any dosage levels. Deterministic effects occur when the threshold level is exceeded and their severity depends on the dosage. Deterministic effects are due to excessive cell death and can be erythema, epilation, skin necrosis or cataract formation.


Radiation Protection Principles

The radiation protection guidelines assume that the health risk of radiation increases with the dose which is called linear no-threshold hypothesis. This has lead to the formulation of ALARA (As Low As Reasonably Achievable) principle as the key to radiation safety guidelines.

As per current laws, the hospital is responsible for the protection of those exposed to ionising radiation within the hospital premises including the patients, personnel and the public. Medical procedures that need use of ionising radiation should be justifiable, safe and should be performed by trained person using appropriate equipments and methods. Any breach of safety regulations prescribed by laws is an offence.

There should be protocols and training of personnel to ensure radiation safety. Dosage restrictions should be stipulated and appropriate monitoring badges should be provided. An audit of the use of ionising radiation, compliance with safety protocols and exposure dosage monitoring is required as per the guidelines. Exposure time should be recorded in the patient case sheet. As the hazards are not immediately evident and also due to ignorance, the compliance with the safety measures is often alarmingly low.

The three basic factors that determine the safety are the exposure time, distance from source and shielding. In simple terms; reduce the exposure time, increase the distance from the source and use appropriate shielding. The exposure to the surgical team is actually greater than in conventional radiography due to the reduced distance, less shielding and exposure time especially during difficult procedures. Lead aprons, thyroid shields and leaded eyewear are a must for personal protection. Though heavier, wraparound aprons are better.

Exposure time and X-ray field size should reduced to the the maximal extent possible. X-ray beam should be well collimated. Simulated skin entrance and exit exposure levels and the scatter radiation levels should be measured by a qualified physicist at all occupied areas around the c-arm to determine the type, number and location of the personal radiation monitors to be used. Ideally a whole body monitor badge should be worn under the lead apron and a badge should be worn outside the thyroid shield. A wrist badge should be worn on the hand closest to the beam to monitor the extremity exposure.

The exposure to the patient is determined by distance from the source, thickness of the patient, kV, mA and the exposure time. Thicker the patient more is the exposure. The closer to the source greater is the exposure. Patient exposure can be reduced by reducing the duration of exposure, increasing the distance from the source and reducing the field size.


Practical Steps to improve radiation safety


X-ray source
  • The X-ray source should be kept as far away from the patient as possible. If the source is closer to the patient the beam is concentrated on a small area increasing the chance of injury.
  • The source should be kept below the operation table whenever possible. The main source of radiation to the personnel is scattering of beam by the patient. When the source is kept below the radiation is scattered on to the ground.
  • When taking lateral or oblique view keep the source away from the personnel. The image intensifier should be towards the personnel.
  • Collimate down to the area of interest. This will decrease the amount of tissue irradiated and the scattering.
Image intensifier
  • Keep it as close as possible to reduce the scattering, to reduce the patient dosage and to obtain a larger field of view.
  • Personnel should stand on the side of image intensifier to reduce exposure to scatter rays.
  • Use the lowest mA possible  as the higher tube current increases the dosage.
  • Larger kVp increases the penetrability of beam allowing the use of a lower mA. But large kVp may reduce contrast.
  • Reduce the exposure time to the minimum. Normal mode fluoroscopy produces 1 to 10 R/min (0.01 to 0.1 Gy/min). HI or boost mode produces 10 to 20 R/min (0.1 to 0.2 Gy/min).
  • Avoid pulse mode and continuous mode.
  • If needed. use pulse mode than continuous mode. Continuous mode increases the dose exponentially. Radiation is 10-20 times more during continuous mode.
  • When using pulse mode, use a lowest frequency possible.
  • Reduce the magnification to the minimum as both digital and geometric magnification increases the dosage. Dose increases at the rate of square of magnification.
  • Radiation is higher in larger patient as a bigger mA increasing the dosage and scatter.

Remember that scatter rays are the main source of radiation to the personnel. Injury from scatter rays can be reduced by use of shields and by increasing the distance from the source. Remember that the lens of the eye and the thyroid are most vulnerable to radiation injury.

  • Use protective aprons, thyroid shields and lead goggles.
  • Exposure from a radiation source decreases by the inverse of the distance squared. Hence stay as far away as possible from the X-ray source.
  • Stand on the side of image intensifier as far as possible.
  • Use dose monitors.
  • Use portable shields if available.
  • Preoperative planning an careful checking of the previous images can help to reduce the number of exposures.
  • Annual dosage limit for hospital workers is 500 mrem for the whole body, 1500 mrem for the eyes and 5000 mrem for all other organs. Dosage limit for pregnant women is no more than 500 mrem (5 mSv) during the entire gestational period and no more than 500 mrem in a month.
Protective shielding
  • Full wrap around type protective gowns are recommended.
  • It should have 0.50 mm Pb in the front panels and 0.25 mm Pb in the back panels.
  • Use protective  thyroid shields with an equivalent of 0.50 mm Pb.
  • Use of leaded glasses to protect the eyes.
  • Protective gloves should have at least a 0.25 mm Pb equivalency. But remember that these gloves do not protect the hands if placed within the primary beam.
  • They should be checked yearly for efficiency.
  • After use the protective aprons and thyroid shields should be stored properly to prevent damage.
  • Lead aprons and thyroid shields with 0.5mm lead thickness provide 85%–95% attenuation of scattered x-rays.



Absorbed dose- The total amount of radiation energy absorbed per volume of tissue exposed.

Effective dose- Depends on the proclivity of tissue or organs exposed to develop stochastic effects and the type of radiation involved.

Tissue-weighting factors is high for breast tissue and ovaries as they are more prone for stochastic effects.

Entrance surface dose

Dose-area product

Collective dose

Background effective dose (BRE) is the radiation from natural sources in the general population. In the United States is approximately 3.1 mSv per year. It is up to 70 mSv per year in Kerala, India due to the naturally occurring thorium coated monazite sand. A pelvic radiograph has an effective dose of ~0.6 mSv hence the BRE = 71 days.

kVP – Kilovolt peak

mA- Milliampere

As per the newer guidelines  gray (Gy) replaces roentgen (R) for exposure. The  gray (Gy) replaces the  rad (rad) as the unit of absorbed dose. And the  sievert (Sv) replaces the  rem (rem) as the unit of equivalent dose.


  • Gout is an inflammatory arthritis caused by deposition and accumulation of monosodium urate crystals in tissues, mainly synovium, cartilage and skin with or without symptoms as a result of long standing hyperuricemia.
  • 90% of gout is due to under excretion and 10% is due to increased synthesis.
  • The stages of gout are hyperuricemia, asymptomatic gout, acute gout, inter-critical gout and chronic gout.
  • It is often associated with metabolic syndrome with insulin resistance, hypertension and diabetes mellitus.
  • Gout and asymptomatic hyperuricemia is associated with significantly elevated risk of chronic lifestyle diseases such as obesity, hypertension, ischaemic heart disease, type 2 diabetes, chronic kidney disease etc.
  • Nephropathy and disorders associated with increased cell turnover can be associated.


  • Uric acid is the end metabolite of purine metabolism in humans.
  • In other species, presence of the enzyme called uricase converts uric acid into highly water soluble allantoin.
  • In humans, the uricase gene is inactivated by the presence of 2 mutations.
  • The level of uric acid in humans is 10 times higher than other species due to the absence of uricase.
  • It is a weak acid and at the physiologic pH exists in the ionic form called urate.
  • Uric acid levels depend on the dietary intake, synthesis and excretion.
  • The limit of solubility of urate is 6.8mg/dL.
  • When exceeded, urate crystal deposition occurs in tissues.
  • Solubility of urate is determined by the following factors
    • pH
    • Body temperature
    • Level of hydration
    • Presence of nucleation factors
    • Concentration of cations

Clinical Features

  • Episodic urate crystal induced acute inflammation of joints, tendons and bursa is the classic picture of acute gout.
  • Acute attack which peaks within just 6–12 hours with overlying erythema is highly suggestive of crystal inflammation though not specific for gout.
  • In recurrent podagra with hyperuricemia, a clinical diagnosis is reasonably accurate but not definitive without crystal confirmation.
  • Lower limbs are more commonly affected than upper limbs.
  • Peripheral joints are more commonly affected than central joints.
  • First metatarsophalangeal joint is the site of presentation (Podagra) in more than 50% of cases. Other sites of first attack are the tarsal joints ankle and knee.
  • More than 80% of the site of first episode is in the lower limbs.
  • The first episode is monoarticular in 90%.
  • Polyarticular onset is seen in less than 1%.
  • Olecranon bursa is the commonest site of first attack in the upper limb.
  • First metatarsophalangeal joint is affected in more than 80% of patients with uncontrolled or untreated gout.
  • Acute attacks are preceded by prodromal symptoms such as mild pain, limitation of motion and discomfort.
  • Acute attacks have an abrupt onset with rapid development of acute inflammation with excruciating pain during the first 24-48 hours.
  • Provocative factors for acute attacks include severe dietary restriction, high purine diet, local trauma and initiation of treatment.
  • Sudden drop in uric acid level results in disintegration of solid aggregations leading to local inflammation.
  • Macroscopic collections of urate crystals is called tophi. More commonly seen in areas subjected to pressure or friction.
  • Limitation of joint movement is due to accumulation of tophaceous deposits in the joints and periarticular tissues.
  • Intraarticular tophi may present with mechanical symptoms mimicking meniscus tear or loose body.
  • Rupture of intradermal tophi may mimic pustules.
  • Persistent joint swelling is called chronic gouty arthritis. It is due to chronic granulomatous inflammation induced by urate crystals. X-rays usually show only minimal destruction, but MRI or USG show extensive soft tissue deposits.

Natural history of untreated gout

  • More than 75% develop subsequent acute attacks.
  • Frequency of attacks increase in 50%.
  • Severity of attack increases in 30%.
  • Polyarticular involvement develops in 40%.
  • Tophaceous burden increases.


Diagnostic investigations are done for

o          Confirmation of gout.

o          Determination of burden of disease.

o          Identification of complications.

o          Identification of other associated rheumatic conditions.

Confirmation of diagnosis

  • Demonstration of MSU crystals in synovial fluid or tophus aspirates is the gold standard for the diagnosis of gout.
  • Synovial fluid should be send for total count, differential count, analysis, gram stain, bacterial culture and biochemical analysis.
  • MSUC are water soluble and is dissolved if preserved in formalin, hence tissue samples to be examined for urate crystals should be fixed in 100% alcohol.
  • In all synovial fluid samples obtained from inflamed joints for diagnosis, search for MSU crystals.
  • During the intercritical period, definite diagnosis can be made by identification of MSU crystals in the asymptomatic joints.
  • Gout and sepsis may coexist, hence do gram staining and culture
  • Serum uric acid levels alone do not confirm or exclude gout, as many with hyperuricemia do not develop gout, and the serum levels may be normal in many with acute attack.
  • In those with a family history of young onset gout, onset of gout under age 25, or with renal calculi determine the renal uric acid excretion.

Determination of burden of disease

  • Number of acute exacerbations.
  • Number and location of joints ever involved by acute attacks.
  • Presence, size, and location of superficial tophi.
  • Persistence of pain, joint swelling, limitation of motion, and deformities.
  • Short 4-joint USG of both knees and first metatarsophalangeal joints.

Look for comorbidities such as obesity, hyperglycaemia, hyperlipidaemia and hypertension.


  • Conventional x-ray
  • Ultrasonography
  • Three-dimensional (3D) multislice imaging via computed tomography (CT),
  • Dual-energy computed tomography (DECT)
  • Magnetic resonance imaging (MRI)


  • Radiographs are not useful in confirming the diagnosis of early or acute gout.
  • Play a minor role in diagnosis.
  • Nonspecific initially.
  • Acute gout attack produces soft tissue swelling.
  • Asymmetric erosive arthropathy especially of the first MTPJ is the characteristic appearance of chronic gouty arthritis.
  • Gouty deposits cause well corticated erosions with typical overhanging margins.
  • New bone formation can be seen in the form sclerosis, osteophytes, bony spurs and, rarely, periosteal deposition and ankylosis.

CT Scan

  • Multislice helical CT scanning can show tophaceous deposits with a typical density of 160–170 Hounsfield units. They are found close to the erosions extending into the soft tissues.

Dual Energy CT

  • Uses 2 X-ray tubes arranged perpendicular to each other using different voltages. It has the potential to detect intra-articular and extra-articular urate crystals which would have been otherwise undetectable.

High resolution ultrasound scan.

  • Serial high resolution ultrasound may be used to assess response to treatment.
  • Highly sensitive for detection of erosions.
  • Double contour sign seen

Diagnosis Criteria

Rome criteria – 1963

(2 of 4 required for diagnosis)

  • Serum uric acid > 7mg/dl in males and >6mg/dl in females
  • Tophus
  • Urate crystals demonstrated in the synovial fluid
  • History of recurrent attacks of joint swelling of abrupt onset which resolves within 2 weeks.

New York criteria – 1968

  • Demonstration of urate crystals in the synovial fluid or tissue.


More than 2 of the following criteria.

  • Tophi
  • History or observation of podagra.
  • History or observation of at least 2 attacks of painful limb swelling of abrupt onset which resolves within 1-2 weeks.
  • History or observation of good response to colchicine within 24 hours.

Haemophilia for the orthopaedic surgeons

Haemophilia is an X-linked genetic coagulation disorder due to deficiency of either coagulation factor VIII or IX. About 80% is due deficiency of factor VIII (Haemophilia A), 15% is due to deficiency of factor IX (Haemophilia B, Christmas disease) and the rest is due to von Willebrand disease. Haemophilia A & B are inherited as X-linked recessive and von Willebrand disease as autosomal dominant inheritance.

heemophilia types

About 400,000 people are affected across the world. Incidence is 1 per 5000 male live births. Mortality rate in haemophiliacs exceed that of normal population by 2.6 times. 2/3rd have family history but 1/3rd of cases are due to new mutations.

Clotting factor VIII is also known as anti-haemophilic factor or globulin. It is encoded by the f8 gene in the long arm of X chromosome (Xq28). It is synthesized by the sinusoidal cells of liver and by the endothelial cells of the body. In the blood, it circulates in an inactive form bound to von Willebrand factor. When activated it separates from von Willebrand factor and plays a key role in the intrinsic coagulation pathway.


  • Hopff in 1828 coined the term haemophilia.
  • Wright first described the prolonged clotting time.
  • Patek and Tailor isolated Factor 8.
  • It is called the royal disease as Queen Victoria (1819-1901) was a carrier who passed on the X-linked gene to 2 out of her 4 daughters as carriers and one of her 5 sons died of haemophilia. One of her grandsons, Alexei born to the Russian tsar Nicholas II also died of the disease.

Milestones in the treatment

1840s – Whole blood transfusion

1923- Plasma transfusion

1950s- Fresh frozen plasma

1960s- Cryoprecipitate

1970- Freeze dried clotting factors

Ward Rounds- A recently neglected part of inpatient care


More than two decades back when I did my house surgeoncy, I had tough time with the length of ward rounds. Ward rounds started at 7:45AM and it would continue beyond 12noon without a coffee break. My feet ached, mind was numb with hypoglycemia. In those moments I used to think why rounds can’t be faster and why it was taking so much of time. But later with a personal experience, that impression changed.

During my early PG days, my grandmother got admitted in the pay ward with a minor surgical problem in the busiest surgical unit. Each day I noticed that she was waiting for the time of rounds. One day, on the operation day of the unit; rounds was not taken till afternoon. My grandmother was unhappy and was wondering why no one has come so far for rounds. I tried to console her by informing her that it was the operation day. Initially she was comforted but soon she started grumbling. Soon it was a full blown tantrum and she refused lunch.

The time flew past the afternoon to evening, I did my best to comfort her without any response. I tried to contact the members of the concerned unit. They were held up in the OT. I gave up the hope of pacifying her and told her that probably there won’t be any rounds as it was already very late. She remained inconsolable. Then there was a knock on the door and the unit chief was standing outside the door. He peeped inside without even stepping in and asked “How are you grandmother? Are you better enough to go home? My grandmother was beaming and became an unrecognisably different person.

From that day I understood the psychological importance of ward rounds to the patient. But it is important for the treating team as well. It helps to establish a rapport with the patient, helps in early detection of complications and often saves one from embarrassment or even legal proceedings.

Over the years I have noticed that doctors as a community have become unaware of the importance of rounds. Rounds is often delegated to junior colleagues and many regard it as a nuisance. The patient is forgotten and more attention is given to the case sheets, investigation reports and the x-ray or MRI images. Some even think it is the best time to catch up with missed calls, emails, Facebook or Whatsapp messages.

Meniscus Lesions Tied to Neuropathic Pain in Knee OA


Meniscal extrusion on MRI significantly associated with increasing pain scores in knee osteoarthritis.

Meniscus lesions, specifically extrusions, were a risk factor for neuropathic pain in patients with knee osteoarthritis (OA), results of a pilot study suggested.

The presence of meniscal extrusion on MRI, in both medial (P=0.006) and lateral (P=0.023) compartments, was significantly associated with increasing neuropathic pain (NP) pain scores in knee OA patients, according to Camille Roubille, MD, of the University of Montreal Hospital Research Center in Quebec, and colleagues.

The presence of meniscal tears in the lateral compartment (P=0.011) was also significantly associated with pain scores, they wrote online in Arthritis Research and Therapy.

“Our finding of an association between NP and lateral meniscal tear is somewhat unexpected as literature indicates that meniscal tears are not usually associated with symptoms,” the authors wrote.

The multicenter, cross-sectional, observational study included 50…
