To summarize the current research progress about influence of patellofemoral osteoarthritis on clinical outcome of unicompartmental knee arthroplasty (UKA).
The recent related literature was extensively reviewed and summarized, including pros and cons to regard the patellofemoral osteoarthritis as the contraindication.
Previous studies regarded patellofemoral osteoarthritis as the contraindication of UKA. Most of current researches show that the damage to the articular cartilage of the patellofemoral joint to the extent of full-thickness cartilage loss has no influence on outcome of UKA. There is no correlation between preoperative anterior knee pain or medial patellofemoral joint degeneration and the clinical outcome. However, lateral subluxation of the patella has an adverse impact on postoperative curative effect. Degeneration of the lateral patellofemoral joint may be a risk factor of the outcome.
Patellofemoral osteoarthritis should not be the absolute contraindication of UKA. The effect of degeneration of the lateral patellofemoral joint is not clear at present, and still needs further studies in the future.
总结髌股关节炎对单髁膝关节置换术（UKA）临床疗效影响的当前研究进展。
广泛回顾和总结近期相关文献，包括将髌股关节炎视为禁忌证的利弊。
既往研究将髌股关节炎视为UKA的禁忌证。目前大多数研究表明，髌股关节软骨损伤至全层软骨缺失程度对UKA疗效无影响。术前膝关节前侧疼痛或髌股内侧关节退变与临床疗效之间无相关性。然而，髌骨外侧半脱位对术后疗效有不利影响。髌股外侧关节退变可能是影响疗效的危险因素。
髌股关节炎不应成为UKA的绝对禁忌证。目前髌股外侧关节退变的影响尚不清楚，未来仍需进一步研究。
