BACKGROUND: In 1967, Wilson described a clinical sign that he thought was diagnostic of medial femoral @entity1843 . He postulated that impingement of the tibial eminence on the @entity75 caused @entity158 and a resultant compensatory lateral rotation during gait. He described reproducing the @entity158 by internally rotating the @entity1 's tibia during knee extension between 90 degrees and 30 degrees of flexion and then relieving that @entity158 by externally rotating the tibia. He correlated healing of the lesion with conversion of the sign from positive to negative. PURPOSE: To assess the validity of Wilson's assertions. STUDY DESIGN: Retrospective clinical and radiographic case analysis. METHODS: Case records from 17 juvenile @entity1 (ages 9 to 12) and 15 adolescent @entity1 (ages 13 to 17) with medial femoral @entity1843 were reviewed for the presence or absence of Wilson's sign at initial and subsequent visits. RESULTS: Of the 32 @entity1 , 24 (75%) with radiographically evident @entity1843 at the initial visit had negative signs. The remaining eight @entity1 with positive signs had conversion of the sign to negative with lesion resolution. CONCLUSIONS: In this series, Wilson's sign was of minimal clinical diagnostic value. When positive, the sign is useful as a clinical monitor during treatment.
