Twenty-five patients who received bilateral total knee prostheses were studied to evaluate the advantages and disadvantages of patellar resurfacing. Only patients with advanced patellofemoral disease were included in the study. In all patients, patellar resurfacing had been done in the right knee but not in the left knee. The DePuy porous-coated implant was used in all cases. Subjective criteria were compared with objective criteria, which included range of motion, knee flexion and extension, and roentgenographic evaluation. The findings in this study suggest that patellar resurfacing can offer the patient a superior knee with regard to pain relief and strength.
对25例接受双侧全膝关节置换术的患者进行了研究，以评估髌骨表面置换的优缺点。该研究仅纳入了患有晚期髌股关节疾病的患者。所有患者的右膝均进行了髌骨表面置换，而左膝未进行。所有病例均使用了Depuy多孔涂层植入物。将主观标准与客观标准进行了比较，客观标准包括活动范围、膝关节屈伸以及X线评估。本研究结果表明，髌骨表面置换在缓解疼痛和增强力量方面可为患者提供更好的膝关节。
