Abstract
A Two cases of osteochondral fracture of the patella were described in young women. One case was acute, and her knees were affected bilaterally at an interval of 42 months. The other was chronic. In both cases, “sky-line” axial projection of the patella revealed a defect in the medial aspect of the patellar facet. At arthroscopy, a defect in the articular surface of the patella and the loose body were detected. Hypermobility, lateralisation and high riding of the patella were also found. The loose bodies were removed, and advancement of the vastus medialis with section of the lateral alar ligament were performed.
