Total knee arthroplasty occasionally does not meet expectations. This randomized clinical trial assessed the effect of restoration of the native patellofemoral height on clinical outcomes. Group I underwent standard patellar bone resection; group II underwent modified patellar bone resection that adjusted the amount of anterior condylar bone removed and the anterior flange thickness. There were no differences in anterior knee pain, Western Ontario and McMaster Universities Arthritis Index scores, or Knee Injury and Osteoarthritis Outcome Score scores. Patellofemoral compartment height restoration versus patellar height alone does not appear to significantly reduce pain or improve function.
全膝关节置换术有时无法达到预期效果。这项随机临床试验评估了恢复正常髌股高度对临床结果的影响。第一组接受标准髌骨骨切除术；第二组接受改良髌骨骨切除术，该手术调整了髁前骨切除量和前凸缘厚度。两组在膝前疼痛、西安大略和麦克马斯特大学骨关节炎指数评分或膝关节损伤和骨关节炎疗效评分方面没有差异。恢复髌股关节间隙高度与单纯恢复髌骨高度相比，似乎并不能显著减轻疼痛或改善功能。
