One hundred and eleven total knee replacements without patellar resurfacing were followed-up for a minimum of 48.8 months (range 48.8-108.2 months; average 78.2 months). Evaluation was performed using the Knee Society Clinical Rating System (KS-CRS). Preoperatively, the mean knee score was 34.3 points and the mean function score was 42.2 points. Postoperatively, this knee score improved to a mean of 91.1 points and the function score improved to mean of 89.6 points at the most recent follow-up. There were no significant differences among the knees with mild, moderate, or severe degenerative change to the patella with regard to the preoperative (p=0.83) and postoperative (p=0.39) knee pain score. It seems likely that the postoperative knee pain is not related to the severity of degenerative change to the patella in total knee arthroplasties performed without patellar resurfacing, and none of those patients required patellar resurfacing to achieve knee pain relief.
111例未进行髌骨表面置换的全膝关节置换术患者接受了至少48.8个月的随访（范围48.8 - 108.2个月；平均78.2个月）。使用膝关节协会临床评分系统（KS - CRS）进行评估。术前，平均膝关节评分为34.3分，平均功能评分为42.2分。术后，在最近一次随访时，膝关节评分提高到平均91.1分，功能评分提高到平均89.6分。对于髌骨轻度、中度或重度退变的膝关节，术前（p = 0.83）和术后（p = 0.39）膝关节疼痛评分无显著差异。在未进行髌骨表面置换的全膝关节置换术中，术后膝关节疼痛似乎与髌骨退变的严重程度无关，并且这些患者中没有一人需要进行髌骨表面置换来缓解膝关节疼痛。
