Cartilage defects of the hip cause significant
pain and may lead to arthritic changes that necessitate hip replacement.
We propose the use of fresh osteochondral allografts as an option
for the treatment of such defects in young patients. Here we present
the results of fresh osteochondral allografts for cartilage defects
in 17 patients in a prospective study. The underlying diagnoses
for the cartilage defects were osteochondritis dissecans in eight
and avascular necrosis in six. Two had Legg-Calve-Perthes and one
a femoral head fracture. Pre-operatively, an MRI was used to determine
the size of the cartilage defect and the femoral head diameter.
All patients underwent surgical hip dislocation with a trochanteric
slide osteotomy for placement of the allograft. The mean age at
surgery was 25.9 years (17 to 44) and mean follow-up was 41.6 months
(3 to 74). The mean Harris hip score was significantly better after
surgery (p <
0.01) and 13 patients had fair to good outcomes.
One patient required a repeat allograft, one patient underwent hip
replacement and two patients are awaiting hip replacement. Fresh
osteochondral allograft is a
