Abstract：
UNLABELLED:Treatment of patellofemoral osteoarthritis in young patients is a challenge for orthopaedic surgeons. Concern about loosening and wear in active young people render arthroplasty more suitable for older patients. Osteochondral allografts may be a good alternative, but reports of experience with such grafts in patellofemoral joints are limited. We retrospectively reviewed our results with fresh osteochondral allografts. Our hypothesis was that these grafts provide relief from osteoarthritis, improve knee function, and delay prosthetic knee replacement. From 1986 to 1999, 14 fresh patellofemoral or patellar allografts were implanted in knees of 11 patients younger than 55 years and diagnosed with advanced secondary osteoarthritis. At last followup (average, 10 years; range, 2.5-17.5 years), eight grafts were in place, four for more than 10 years and two for more than 5 years. Of the nonsurviving allografts, three survived more than 10 years. Radiographs of the knees with intact allografts showed mild or no degenerative changes. Average Knee Society scores improved (preoperative to last followup), with knee scores improving from 46 points (range, 38-60 points) to 82 points (range, 35-100 points) and functional scores from 30 points (range, 10-60 points) to 75 points (range, 20-100 points). Fresh osteochondral allografts can provide relief from the arthritic condition, improve knee function, and delay prosthetic knee replacement. LEVEL OF EVIDENCE:Therapeutic study, Level IV (case series). See the Guidelines for Authors for a complete description of levels of evidence.
