One hundred seven patients were examined who had undergone patellectomies between 1965 and 1983 (113 patellectomies). The mean follow-up time was 10.5 years (3-17.5 years) and the average age of the patients 42.6 years. There were three distinct groups of operative techniques: (1) the purse-string technique in 40 patellectomies; (2) the vastus medialis technique in 24 patellectomies; (3) other techniques in 49 patellectomies. The indications for patellectomy were: chondromalacia, 56 cases; comminuted patellar fractures, 32 cases; arthritis, 17 cases; recurrent patellar dislocations, 8 cases. The patients were examined for pain, rage of motion, giving way, swelling, quadriceps strength, activity and cosmetic results (interview, physical examination, Cybex and radiographic study). In the purse-string technique group, 81% of the cases ended up with good or excellent results; in the vastus medialis group there were 79% and in the third group only 73% good or excellent results. Among the patellectomies for comminuted fractures, 75% had excellent results. The clinical outcome of patelletomy for arthritis is fair, for recurrent dislocation favorable, and for chondromalacia variable and not predictable.
对1965年至1983年间接受髌骨切除术的107例患者（共113例髌骨切除术）进行了检查。平均随访时间为10.5年（3至17.5年），患者平均年龄为42.6岁。手术技术分为三组：（1）40例髌骨切除术采用荷包缝合法；（2）24例髌骨切除术采用股内侧肌技术；（3）49例髌骨切除术采用其他技术。髌骨切除术的适应症为：软骨软化症56例；髌骨粉碎性骨折32例；关节炎17例；复发性髌骨脱位8例。对患者进行了疼痛、活动范围、打软腿、肿胀、股四头肌力量、活动情况和美容效果（访谈、体格检查、Cybex测试和影像学检查）的检查。在荷包缝合法组中，81%的病例最终结果为良好或优秀；在股内侧肌组中为79%，而在第三组中只有73%的结果为良好或优秀。在髌骨粉碎性骨折的髌骨切除术中，75%的结果为优秀。关节炎患者髌骨切除术的临床结果一般，复发性脱位患者的结果较好，软骨软化症患者的结果不一且难以预测。
