Abstract
Four patients who had old osteochondral fracture of the patella have undergone autogenous osteochondral graft from the non-weight bearing area of the lateral femoral condyle.
The osteochondral fracture had been caused by traumatic (1), recurrent (2) or habitual (1) dislocation of the patella. The average age of the patients at the time of grafting was 21.5 years (range, 13 to 31) .
The mean follow-up interval after operation was 1.1 years (range, 8 months to 1-year, 4 months) . The grafted fragments were found at arthroscopy to be in place without cartilage breakage or sapphire pin protrusion. Two patients required arthroscopic manipulation, but finally all cases regained a full range of motion, and were relieved of their patello-femoral pain, swelling and dislocation. Only one patient had retropatellar crepitation.
