We analyzed 40 patients (42 knees) who underwent patellectomy an average of 12 years ago. Although there was good relief of pain with very good function in several patients, we felt that only 48% of the patients could be rated as good or very good, overall. Prognosis was best in patients under the age of 30. Bad prognostic signs were preexisting gonarthrosis and previous total meniscectomy. There was no difference in results for patients who underwent patellectomy acutely, as compared to those who had patellectomy as a secondary procedure. Therefore, we recommend that patella-sparing procedures be utilized first before consideration of patellectomy.
我们分析了40例患者（42个膝关节），这些患者平均在12年前接受了髌骨切除术。虽然有几位患者疼痛得到了很好的缓解，功能也非常良好，但总体而言，我们认为只有48%的患者可被评为良好或非常好。30岁以下的患者预后最佳。预后不良的迹象是存在膝关节病和既往全半月板切除术。与接受二期髌骨切除术的患者相比，急性接受髌骨切除术的患者结果没有差异。因此，我们建议在考虑髌骨切除术之前首先采用保留髌骨的手术。
