Peri-prosthetic patella fracture is the second most common peri-prosthetic fracture after total knee arthroplasty. This report presented the treatment results in 6 patients with peri-prosthetic patella fractures. From January 2015 to February 2019, six patients with peri-prosthetic patella fractures were treated. The mean age at surgery was 64 years (range, 48-72 years). Four patients with displaced fractures were treated surgically, and two patients with non-displaced fractures were treated non-surgically. Outcomes were assessed in terms of motion, functional knee score, and Knee Society score. The mean follow-up period lasted 16 months (range: 12-20 months). The average arc of motion was 110° (range: 80°-130°). The mean functional knee score was 77 (range: 70-87). The mean Knee Society score was 84 (range: 75-89). The non-surgical treatment may be a good choice for non-displaced peri-prosthetic patella fractures. For displaced fractures, surgical treatments yielded good functional outcomes. LEVEL OF EVIDENCE: IVa.
人工膝关节周围髌骨骨折是全膝关节置换术后第二常见的人工关节周围骨折。本报告介绍了6例人工膝关节周围髌骨骨折患者的治疗结果。2015年1月至2019年2月，对6例人工膝关节周围髌骨骨折患者进行了治疗。手术时的平均年龄为64岁（范围48 - 72岁）。4例移位骨折患者接受了手术治疗，2例无移位骨折患者接受了非手术治疗。根据活动度、膝关节功能评分和膝关节协会评分对结果进行评估。平均随访期为16个月（范围12 - 20个月）。平均活动弧度为110°（范围80° - 130°）。膝关节功能评分平均为77分（范围70 - 87分）。膝关节协会评分平均为84分（范围75 - 89分）。非手术治疗可能是无移位人工膝关节周围髌骨骨折的一个不错选择。对于移位骨折，手术治疗产生了良好的功能结果。证据级别：IVa。
