The results of partial patellectomy as a treatment for displaced patellar fractures were assessed retrospectively with use of clinical, radiographic, and isokinetic strength-testing criteria. Forty patients who had been followed for an average of 8.4 years were studied. In the extremity that had been operated on, the mean active range of motion was 94 per cent, the circumference of the thigh was 100 per cent, and the strength of the quadriceps was 85 per cent of these measurements in the contralateral extremity. The over-all result was rated as excellent in twenty patients, good in eleven, fair in six, and poor in three. There was a significant statistical correlation between the type of fracture and the outcome. The results of this study indicate that partial patellectomy can be an effective treatment for selected patellar fractures.
我们采用临床、影像学和等速肌力测试标准，对部分髌骨切除术治疗移位性髌骨骨折的结果进行了回顾性评估。研究了平均随访8.4年的40例患者。在接受手术的肢体中，平均主动活动范围为94%，大腿周长为100%，股四头肌力量为对侧肢体这些测量值的85%。总体结果评定为优秀的有20例，良好的有11例，尚可的有6例，差的有3例。骨折类型与结果之间存在显著的统计学相关性。本研究结果表明，部分髌骨切除术可以作为某些髌骨骨折的有效治疗方法。
