One hundred fifty-nine Mod II unicompartmental knee arthroplasties were reviewed. The follow-up period ranged from 2 to 10 years (average, 4 years and 6 months). Osteoarthritis was the most common reason for arthroplasty (108 cases). The patients' age at the time of operation averaged 72 years (range, 28-92 years). The diagnosis directly influenced the quality of the final results, which were assessed according to pain, range of motion, stability, and function. Patients with osteoarthritis and medial condyle osteonecrosis had the best results. The average flexion angle obtained was 115 degrees, and the average residual axial deviation was 6 degrees for varus deformities and 8 degrees for valgus deformities. Nine failures, including two deep infections, four femorotibial subluxations, two cases of deterioration of the opposite compartment, and one loosening, required eight revision procedures. Knee instability due to bony loss, much more frequent in osteoarthritis than pure ligamentous laxity, was regularly corrected with this procedure.
回顾了159例第二代单髁膝关节置换术。随访时间为2至10年（平均4年6个月）。骨关节炎是进行关节置换术最常见的原因（108例）。患者手术时的平均年龄为72岁（范围28 - 92岁）。诊断直接影响最终结果的质量，最终结果根据疼痛、活动范围、稳定性和功能进行评估。骨关节炎和内侧髁骨坏死患者的结果最佳。获得的平均屈曲角度为115度，内翻畸形的平均残余轴向偏差为6度，外翻畸形为8度。9例失败病例，包括2例深部感染、4例股骨胫骨半脱位、2例对侧关节腔退变和1例松动，需要进行8次翻修手术。由于骨质丢失导致的膝关节不稳定，在骨关节炎中比单纯韧带松弛更常见，通过该手术可定期得到纠正。
