Numerous methods for creating symmetric flexion and extension gaps during knee arthroplasty in valgus knees have been proposed, and no consensus exists about the optimal technique. The "pie crust" technique for lateral soft tissue releases has been used extensively, yet few clinical results have been published. In this study, the clinical outcomes of 24 consecutive knees in 24 patients in whom this method was used in conjunction with a cemented posterior-stabilized prosthesis were evaluated. At a mean of 54 months' (range 24-69 months) follow-up, the knees were performing well with a mean Knee Society score of 97 (range 87-100) and mean range of motion of 121 degrees (range 100 degrees -145 degrees). Importantly, there were no clinical failures or cases of postoperative instability and no cases of radiographic loosening or wear.
已经提出了许多在膝外翻膝关节置换术中创建对称屈伸间隙的方法，但对于最佳技术尚无共识。“派皮”技术用于外侧软组织松解已被广泛应用，但很少有临床结果发表。在本研究中，评估了24例患者连续24个膝关节采用该方法联合骨水泥固定后稳定型假体的临床结果。平均随访54个月（范围24 - 69个月）时，膝关节功能良好，膝关节协会平均评分为97分（范围87 - 100分），平均活动范围为121度（范围100度 - 145度）。重要的是，没有临床失败或术后不稳定的病例，也没有影像学松动或磨损的病例。
