Displacement of the medial collateral ligament (MCL) into the medial knee joint is an extremely rare finding associated with MCL tears and is easily diagnosed on magnetic resonance imaging. A case of intra-articular interposition of the MCL during a severe knee injury is presented. A radiolucent "fat stripe" sign and adjacent skin dimpling on radiographs may be relatively specific indicators of this injury.

Objective: To quantify changes in magnetic resonance imaging signals from the deep and superficial capsulo-ligamentous planes and the medial collateral ligament in flares of knee osteoarthritis.
Patients and Methods: Preliminary prospective study of ten patients with medial compartment knee osteoarthritis meeting American College of Rheumatology criteria and associated with a Lequesne index of 5 or more. A grid was used to evaluate signal changes as compared to the opposite (asymptomatic) knee. Magnetic resonance images were read independently by two radiologists blinded to clinical data.
Results and Discussion: In all ten patients the capsulo-ligamentous planes and medial collateral ligament generated low signal on T1 images and high signal on T2 images. No significant changes were seen in the asymptomatic knee. The evaluation grid produced satisfactory interobserver agreement.
Conclusion: Flares of medial compartment knee osteoarthritis are associated with changes in magnetic signal as compared to the contralateral asymptomatic osteoarthritic knee. The grid developed for this study could be used to evaluate the effects of treatment in a larger number of patients.

To estimate the risk and evaluate the long-term outcome of knee and ankle injuries in former national team elite football, 69 players were randomly selected, followed by clinical and stress radiographic examinations. Thirty-nine players (49 knees) had had knee injuries and 29 ankle injuries (35 ankles). The median time from injury until study examination was 25 years. The knee injuries were tears of the medial collateral ligament (MCL) in 24 cases combined with rupture of the anterior cruciate ligament (ACL) and meniscus lesions in three. Meniscus lesions had occurred in 17 cases including three combined with ACL and MCL and another two with ACL ruptures. Isolated rupture of the ACL had occurred in four cases. The ankle lesions were in 26 of 35 cases ruptures of the lateral ligaments. In all, 12 players had completely stopped football and three had changed occupation. Signs of arthritis were present in 63% of the injured knees and in 33% of the injured ankles. The incidence of arthritis in the group of 17 uninjured players was 26% in the knee and 18% the ankle. In elite football players knee and ankle injuries seem to have a serious long-term outcome, but also uninjured players have a higher risk of developing arthritis than the normal population.
