Abstract

Background

Quadriceps tendon rupture (QTR) is an uncommon injury. In chronic QTR there may be a large defect and direct repair is not possible with sutures or transosseous anchors. There is no gold standard surgical procedure for the treatment of chronic QTR. We propose a novel technique in which the quadriceps tendon (QT) is reconstructed using a transfer of ipsilateral sartorius tendon.

Methods

Between January 2002 and April 2020, 19 patients undergoing sartorius muscle transfer for chronic QTR were prospectively recruited. The Knee Society Score (KSS), range of motion (ROM), and Medical Research Council (MRC) Scale for QT muscle strength were collected preoperatively and at a minimum of 2 years follow up.

Results

The mean age of our cohort was 53.4 ± 9.8 years with a female patient count of 12 (54%). The mean body mass index recorded was 28.5 ± 3.2 kg/m² (range 23–30). At the mean follow up of 53.4 ± 28.1 months the mean KSS was 90.9 ± 6.3 (range 80–100) (P < 0.05), the mean ROM was 119.5 ± 9.9° for flexion (range 100–130) (P < 0.05) and the mean extension lag was 3.8 ± 5.1° (range 0–15) (P < 0.05). The mean MRC scale was 4.5 ± 0.7 (range 3–5) (P < 0.05). The most frequent complication was QT hypotrophy; it was noted in 14 patients.

Conclusion

Satisfactory clinical outcomes of ipsilateral sartorius muscle transfer for chronic QTR can be expected a mean of 4.4 years after surgery.

缝匠肌转移治疗慢性股四头肌肌腱断裂：一项前瞻性研究。

背景：股四头肌腱断裂（QTR）是一种不常见的损伤。慢性股四头肌腱断裂可能存在较大的缺损，无法通过缝合或经骨锚直接修复。目前还没有治疗慢性 QTR 的金标准手术方法。我们提出了一种新技术，利用同侧萨尔图里肌腱的转移重建股四头肌腱（QT）：方法：2002 年 1 月至 2020 年 4 月间，我们前瞻性地招募了 19 名因慢性 QTR 而接受萨尔特里肌转移的患者。在术前和至少两年的随访中收集膝关节社会评分（KSS）、活动范围（ROM）和医学研究委员会（MRC）QT肌力量表：患者的平均年龄为 53.4 ± 9.8 岁，其中女性患者 12 人（占 54%）。平均体重指数为 28.5 ± 3.2 kg/m2（23-30）。平均随访时间为（53.4 ± 28.1）个月，平均 KSS 为（90.9 ± 6.3）（范围为 80-100）：同侧腓肠肌转移治疗慢性 QTR 的临床疗效令人满意，平均可在术后 4.4 年实现。
