A Hoffa fracture is an unstable intra-articular break that is generally treated with surgery.
To evaluate the feasibility and clinical outcomes of using a suture anchor combined with auxiliary fixation for the treatment of a lateral femoral condyle Hoffa fracture.
The study retrospectively reviewed 8 patients (5 males and 3 females) with a lateral femoral condyle Hoffa fracture who had been treated by combining a suture anchor with auxiliary fixation between January 2016 and April 2020. The mean age of patients was 37.5 years (ranging from 23 to 45). According to Letenneur's classification, there were 4 cases of type I, 2 cases of type II, and 2 cases of type III fractures. The clinical outcomes were assessed using Letenneur's functional assessment.
The follow-up duration ranged between 14-24 months. All patients achieved primary healing of the incision and fracture union, as well as normal flexion and extension of the knee joint, with 7 cases showing excellent outcomes and 1 case showing a good outcome. No postoperative complications, such as fracture displacement, anchor loosening, or fracture malunion, occurred in this series.
Our results indicated that a suture anchor, combined with external fixation, was an effective treatment for a lateral femoral condyle Hoffa fracture. Accordingly, this procedure is worthy of wider clinical application.
Hoffa 骨折是一种不稳定的关节内骨折，通常需要手术治疗。
评估使用缝线锚钉联合辅助固定治疗外侧股骨髁 Hoffa 骨折的可行性和临床效果。
本研究回顾性分析了 2016 年 1 月至 2020 年 4 月期间采用缝线锚钉联合辅助固定治疗的 8 例外侧股骨髁 Hoffa 骨折患者（5 例男性，3 例女性）。患者的平均年龄为 37.5 岁（范围 23-45 岁）。根据 Letenneur 分类，Ⅰ型骨折 4 例，Ⅱ型骨折 2 例，Ⅲ型骨折 2 例。采用 Letenneur 功能评估评估临床结果。
随访时间为 14-24 个月。所有患者切口均一期愈合，骨折愈合，膝关节屈伸正常，7 例疗效优，1 例疗效良。本研究未发生骨折移位、锚钉松动或骨折畸形愈合等术后并发症。
缝线锚钉联合外固定治疗外侧股骨髁 Hoffa 骨折是一种有效的方法，值得更广泛的临床应用。
