350 knees were evaluated in a prospective, randomized, double-blinded study of selective patellar resurfacing in primary total knee arthroplasty. Knees with exposed bone on the patellar articular surface were excluded. 327 knees were evaluated at a mean follow-up of 7.8years. 114 knees followed for greater than 10 years were analyzed separately. Satisfaction was higher in patients with a resurfaced patella. In patients followed for at least 10 years, no significant difference was found. No difference was found in KSS scores or survivorship. No complications of patellar resurfacing were identified. The vast majority of patients with remaining patellar articular cartilage do very well with total knee arthroplasty regardless of patellar resurfacing. Patient satisfaction may be slightly higher with patellar resurfacing.
在一项关于初次全膝关节置换术中选择性髌骨表面置换的前瞻性、随机、双盲研究中，对350个膝关节进行了评估。髌骨关节面有暴露骨质的膝关节被排除在外。在平均7.8年的随访期内对327个膝关节进行了评估。对随访超过10年的114个膝关节进行了单独分析。髌骨表面置换的患者满意度更高。在随访至少10年的患者中，未发现显著差异。在膝关节协会（KSS）评分或假体生存率方面未发现差异。未发现髌骨表面置换的并发症。无论是否进行髌骨表面置换，绝大多数保留髌骨关节软骨的患者在全膝关节置换术后情况良好。髌骨表面置换可能会使患者满意度略高。
