Two cases of osteochondral fracture of the lateral femoral condyle were surgically treated. One patient is a 16-year-old girl who fell during hurdlerace. In this case, this fracture resulted from patellar dislocation. The fragment was surgically removed. Another patient is a 26-year-old man who was forced to overstretch his right knee during baseball. The operative findings suggested that the mechanism of this fracture was a tibiofemoral contact by overstretching the knee. The fragment was removed and the original site was shaved down.
