Patellar resurfacing is performed in total knee arthroplasty (TKA) to improve pain in the anterior compartment of the knee joint and to restore proper coordination and movement of the patellofemoral joint. The purpose of this study was to analyze differences in clinical outcomes according to patellar resurfacing in patients who underwent bilateral TKA.
Forty-three patients who underwent bilateral primary TKA with patellar resurfacing on one side only were included. Patellar resurfacing was performed selectively according to the status of the patella cartilage surface. Knee Society score (knee and function), Feller score, Kujala score, and Samsung Medical Center (SMC) score (pain and function) were evaluated.
There were no significant differences in Knee Society pain and function scores, Feller score, Kujala score, and SMC pain and function scores according to patellar resurfacing. On the comparison of SMC scores, there was no difference except for two questions.
It is advisable not to perform resurfacing on normal patellae. However, in order to apply this result to damaged patellae, comparative studies between resurfaced patellae and damaged patellae are needed.
髌骨表面置换术在全膝关节置换术中应用，以改善膝关节前间室疼痛，并恢复髌股关节的适当协调性和运动。本研究旨在分析单侧全膝关节置换术中髌骨表面置换术患者的临床结果差异。
纳入 43 例仅一侧行单侧初次全膝关节置换且行髌骨表面置换的患者。根据髌骨软骨表面的状况，选择性地进行髌骨表面置换。评估膝关节学会评分（膝关节和功能）、费勒评分、库雅拉评分和三星医疗中心（SMC）评分（疼痛和功能）。
髌骨表面置换术与膝关节学会疼痛和功能评分、费勒评分、库雅拉评分和 SMC 疼痛和功能评分无显著差异。SMC 评分比较中，除两个问题外，无差异。
对于正常的髌骨，不建议进行表面置换。然而，为了将这一结果应用于受损的髌骨，需要对表面置换髌骨和受损髌骨进行对比研究。
