Early results with a total patellofemoral joint replacement arthroplasty prosthesis

This report concerns a new prosthesis for total patellofemoral joint replacement. Patients severely disabled due to isolated patellofemoral arthritis in whom all other treatment options had been tried and failed, or were not indicated, became candidates for this surgery. Fifteen patients met these criteria and were followed an average of 3.75 years (range: 2.25-5.5 years). Using the Activities of Daily Living Scale, 14 of 15 patients (93%) had excellent (85%-100%) or good (75%-84%) results, and 1 was fair (65%-74%).
