Results of 211 total knee arthroplasty operations were retrospectively evaluated to identify patients with knees at greatest risk for the development of patellofemoral complications and to determine the incidence and type of patellofemoral complications associated with different patellar implants. Patellofemoral complications occurred in 27 knees (12.8%). Osteoarthritis and obesity were associated with an increased incidence of patellofemoral problems. Significantly higher rates of patellofemoral complications were noted with metal-backed patellar implants and with patellar components implanted without cement. The loosening rate with cementless fixation was 13.5%. The lowest rate of patellofemoral complications following total knee arthroplasty was obtained with all-polyethylene domed patellar components implanted with cement.
对211例全膝关节置换手术的结果进行回顾性评估，以确定发生髌股并发症风险最高的膝关节患者，并确定与不同髌骨植入物相关的髌股并发症的发生率和类型。27例膝关节（12.8%）发生了髌股并发症。骨关节炎和肥胖与髌股问题发生率增加相关。金属背衬髌骨植入物和非骨水泥植入的髌骨组件的髌股并发症发生率显著更高。非骨水泥固定的松动率为13.5%。全聚乙烯圆顶髌骨组件骨水泥植入后，全膝关节置换术后髌股并发症发生率最低。
