全膝关节置换术中进行的髌骨表面置换术 无助于术后功能恢复

Patellar Surface Replacement Performed during Total Knee Arthroplasty Does Not Promote Postoperative Functional Recovery

摘要: 研究跟踪了55例未行髌骨表面置换术的膝关节置换手术患者，随访时间15个月。评估采用膝关节学会临床评级系统(KS-CRS)进行。术前膝关节平均评分为35.1分，平均功能评分为44.5分。术后，膝关节评分提升至90.8分，功能评分在最近一次随访中均值提升至88.7分。在术前(P = 0.85)和术后(P = 0.36)膝关节疼痛评分中，轻度、中度或重度退行性改变的膝关节之间无显著差异。术后产生的膝关节疼痛很可能与未进行髌骨表面置换的全膝关节置换手术中髌骨退行性变化的严重程度无关，且这些患者不具备需要髌骨表面置换来缓解膝盖疼痛的手术指征。

Abstract: This study included 55 patients who underwent total knee arthroplasty without patellar resurfacing and were followed for 15 months. Clinical assessments were performed using the Knee Society Clinical Rating System (KS-CRS). The mean preoperative knee score was 35.1, and the mean function score was 44.5. Postoperatively, the knee score rose to 90.8, while the mean function score at the final follow-up improved to 88.7. No significant differences in preoperative (P = 0.85) or postoperative (P = 0.36) knee pain scores were observed among knees with mild, moderate, or severe degenerative changes. In total knee arthroplasty without patellar resurfacing, postoperative knee pain was not significantly associated with the severity of patellar degenerative changes, suggesting that these patients did not meet surgical indications for patellar resurfacing to relieve knee pain.
