From 1977 through 1987, 21 meniscal-bearing unicompartmental knee arthroplasties (UKAs) were performed on 20 patients in preference to a distal femoral or proximal tibial osteotomy for unicompartmental knee arthritis. Preoperative diagnoses were osteoarthritis (14 cases), posttraumatic arthritis (5 cases), and rheumatoid arthritis (1 case). Eighteen UKAs (7 lateral, 11 medial) were followed for 24 to 132 months (mean, 34). Using the New Jersey Orthopedic Hospital Knee Scoring Scale, good to excellent clinical results were found in 16 (89%) of the UKAs followed for at least two years. These scores represent significant improvement over preoperative evaluation, (paired t test, P less than or equal to .05). No statistical difference was noted in postoperative results between the lateral or medial arthroplasties (Student's t test, P less than or equal to .05).
从1977年至1987年，对20例患者实施了21例半月板承重单髁膝关节置换术（UKA），优先于单髁膝关节关节炎的股骨远端或胫骨近端截骨术。术前诊断为骨关节炎（14例）、创伤后关节炎（5例）和类风湿关节炎（1例）。18例UKA（7例外侧，11例内侧）随访24至132个月（平均34个月）。使用新泽西骨科医院膝关节评分量表，在至少随访两年的UKA中，16例（89%）获得了良好至优秀的临床结果。这些评分相较于术前评估有显著改善（配对t检验，P≤0.05）。外侧或内侧置换术后结果无统计学差异（Student t检验，P≤0.05）。
