To determine the role of unicompartmental knee replacement in knee arthroplasty and, in particular, the design and function of the ICLH (Finsbury Prosthetics Ltd., London, UK) knee prosthesis, the authors report their experience with 18 patients (15 women and 3 men, mean age 73 years), who underwent unicompartmental knee replacement with this prosthesis. The prosthesis failed in five (27.8%) cases, but in the remainder the results were good to excellent over a follow-up extending to 6 years (mean 4.5 years). The main problem with the ICLH prosthesis is the linear wear of the plastic of the tibial component, caused by a sharp radius at the edge of the femoral component. This leads to fracture and breakdown of the tibial portion. Because the short-term results are good but the long-term results are poor, the authors suggest that the ICLH unicompartmental knee prosthesis should be reserved for use in patients whose life expectancy is short.
为确定单髁膝关节置换在膝关节置换术中的作用，尤其是英国伦敦芬斯伯里假肢有限公司生产的ICLH膝关节假体的设计和功能，作者报告了18例接受该假体单髁膝关节置换患者（15名女性和3名男性，平均年龄73岁）的经验。该假体在5例（27.8%）中失败，但其余患者在长达6年（平均4.5年）的随访中结果良好至优秀。ICLH假体的主要问题是胫骨部件塑料的线性磨损，这是由股骨部件边缘的尖锐半径导致的。这会导致胫骨部分骨折和损坏。由于短期结果良好但长期结果不佳，作者建议ICLH单髁膝关节假体应保留用于预期寿命较短的患者。
