PURPOSE To assess the most common presenting symptoms, clinical outcomes, and patient satisfaction following treatment of either snapping medial pes anserinus hamstrings or snapping lateral biceps femoris tendons. METHODS Consecutive patients with a minimum 2-year follow-up after isolated medial hamstring release for a diagnosis of medial snapping pes anserinus tendons or patients treated with primary biceps repair for lateral snapping biceps femoris tendons were evaluated. Clinical outcome scores of the following domains were collected: SF12, WOMAC score, Lysholm Knee Survey, and a simple numeric patient satisfaction score (0-10). Statistical analysis was performed with paired t-tests between preoperative and postoperative scores. RESULTS At an average follow-up of 4.6 years (range 2.0-8.6 years) with two patients lost to follow-up, six consecutive patients (three male, three female) with seven knees were diagnosed with medial snapping pes anserinus tendons and treated with semitendinosus and gracilis tenotomies. Seven knees in seven patients (three male, four female) were diagnosed with lateral snapping biceps femoris tendons and were treated with an isolated biceps femoris repair. Nine of 13 patients were able to return to full desired activities/pre-operative level of sporting activities (4/6 medial, 5/7 lateral. Lysholm and SF-12 scores improved from preoperative to post-operative status for patients with snapping biceps femoris. Only patients undergoing primary biceps repair showed improvement across all WOMAC domains. Patients with medial hamstring tenotomy demonstrated improvement in Lysholm scores. Median postoperative satisfaction for both pathologies was 7 out of 10. CONCLUSION Medial hamstring release for snapping pes anserinus and isolated biceps repair for lateral snapping biceps femoris yields improvement in patient satisfaction and clinical outcomes at mid-term follow-up. LEVEL OF EVIDENCE IV.

膝盖后部肌腱折断的识别和治疗可改善患者的临床疗效。

目的评估在治疗后臀肌media肌肌腱肌腱断裂或股二头肌外侧肌腱断裂后最常见的症状，临床结果和患者满意度。方法对连续患者进行至少2年的随访，以孤立的内侧ham绳肌释放后进行诊断，以诊断内侧an曲肌腱或接受二头肌原发性股二头肌修复的患者。收集以下领域的临床结局评分：SF12，WOMAC评分，Lysholm膝盖调查和简单的患者满意度数字（0-10）。术前和术后评分之间采用配对t检验进行统计学分析。结果平均随访4.6年（2.0-8.6年），其中两名患者失访，连续六个患者（七个男性，三个男性，三个女性）被诊断患有内侧snap肌腱断裂，并接受了半腱肌和gra肌肌腱切开术治疗。七名患者（三名男性，四名女性）中的七个膝盖被诊断出股外侧肱二头肌肌腱断裂，并接受了单独的股二头肌修复术治疗。13名患者中有9名能够恢复到完全所需的活动/术前运动水平（内侧4/6，外侧5/7。对于二头肌突然发作的患者，Lysholm和SF-12得分从术前状态改善到术后状态仅接受二头肌一次修复的患者在所有WOMAC区域均表现出改善，内侧绳肌腱切开术患者的Lysholm评分得到改善。两种病理的术后中位满意度为10分之7。结论中期肌内侧release绳肌松解和ser肌外侧肱二头肌的孤立二头肌修复可提高患者满意度和临床结局。证据级别IV。
