BACKGROUND
The occurrence of chronic knee dislocation is rare. To the best of our knowledge, total knee arthroplasty for treatment of chronic anterior knee dislocation has not been reported.
METHOD
This report describes 3 cases of chronic anterior knee dislocation treated by total knee arthroplasty.
RESULTS
Three female patients with chronic anterior knee dislocation were treated by hinged prosthesis total knee arthroplasty using the Insall rectus snip approach. At a mean of 17 months (range, 12-24 months) of follow-up, all patients showed a painless stable prosthesis and expressed satisfaction with the results.
CONCLUSIONS
Total knee arthroplasty for chronic anterior knee dislocation is a challenging procedure. The Insall rectus snip approach with quadriceps release and constrained prosthesis is recommended.
背景
慢性膝关节脱位的发生较为罕见。据我们所知，尚未有全膝关节置换术治疗慢性膝关节前脱位的报道。
方法
本报告描述了3例采用全膝关节置换术治疗的慢性膝关节前脱位病例。
结果
3例慢性膝关节前脱位女性患者采用Insall直肌切断入路，使用铰链式假体进行全膝关节置换术。平均随访17个月（范围12 - 24个月），所有患者的假体均稳定且无痛，对结果表示满意。
结论
全膝关节置换术治疗慢性膝关节前脱位是一项具有挑战性的手术。推荐采用Insall直肌切断入路，同时松解股四头肌并使用限制性假体。
