The authors report a prospective study of the first 51 cementless P.C.A. unicompartmental arthroplasties performed for osteoarthritis of the knee by one surgeon. Forty-two medial prostheses in 38 patients and 9 lateral prostheses in 9 patients were reviewed at a minimum of 2 years after surgery. Patients were assessed using the HSS score. In the medial joint replacement group, 37 (88%) had an excellent or good result, 3 (7%) were fair, and 2 (5%) poor. Subjectively 37 (88%) were good, 2 (5%) were fair, and 3 (7%) had a poor result. All of the lateral joint replacements had an excellent or good result. This improvement was due to pain relief and increased functional ability; preoperative range of movement was maintained or only slightly improved. There were five unsatisfactory results, three due to technical errors (one requiring revision), one a failure of patient selection, and the last an unexplained synovitis causing persistent discomfort. The early results for the cementless PCA unicompartmental knee arthroplasty are encouraging, with a satisfactory result in 90% of patients.
