The partial articular supraspinatus tendon avulsion (PASTA) lesion repair remains a topic of debate. We have performed in situ repair of PASTA lesions using a potentially viable threading lasso fixation technique. This retrospective case series aimed to evaluate the clinical outcomes of PASTA lesion repair using threading lasso fixation. To the best of our knowledge, this is the first study to review this technique and its outcomes in terms of pain and upper extremity function.
Twenty-five patients with PASTA lesions who were treated with threading lasso fixation were reviewed. All patients were followed up for at least 1 year. Preoperative and follow-up data were retrospectively collected and reviewed. Clinical outcomes were assessed to evaluate the efficacy of the surgery.
There were no postoperative complications. The average follow-up period was 25.7 (22-27) months. At the last follow-up, all patients underwent follow-up magnetic resonance imaging; only two cases showed a partially healed tendon and no case converted to full-thickness tear. Furthermore, shoulder pain decreased and mobility was recovered, with statistically significant differences in all scoring measures. Specifically, the mean visual analog scale score decreased from 5.4 ± 1.2 before surgery to 1.1 ± 0.8 at the last follow-up (t = 14.908, P < 0.01), and the mean American Shoulder and Elbow Surgeons Shoulder Assessment Form score improved significantly from 51.6 ± 6.4 to 89.3 ± 5.2 (t = 22.859, P < 0.01). Additionally, the mean University of California Los Angeles score improved from 17.8 ± 3.5 preoperatively to 32.3 ± 1.4 (t = 19.233, P < 0.01).
Arthroscopic repair using threading lasso fixation is a novel transtendinous technique for patients with partial articular supraspinatus tendon avulsion. Tendon integrity is preserved with this method, which may result in improved function. Overall, threading lasso fixation technique is an effective treatment.
部分关节突上冈肌腱撕脱（PASTA）病变的修复仍然存在争议。我们使用一种潜在可行的穿线套圈固定技术对 PASTA 病变进行了原位修复。这项回顾性病例系列旨在评估使用穿线套圈固定修复 PASTA 病变的临床结果。据我们所知，这是第一项评估该技术及其在疼痛和上肢功能方面的结果的研究。
回顾性分析 25 例接受穿线套圈固定修复的 PASTA 病变患者。所有患者均随访至少 1 年。回顾性收集和分析术前和随访数据。评估临床结果以评估手术的疗效。
无术后并发症。平均随访时间为 25.7（22-27）个月。末次随访时，所有患者均接受了随访磁共振成像检查；仅 2 例显示部分愈合肌腱，无全层撕裂病例。此外，肩部疼痛减轻，活动度恢复，所有评分指标均有统计学差异。具体而言，视觉模拟评分从术前的 5.4±1.2 降至末次随访时的 1.1±0.8（t=14.908，P<0.01），美国肩肘外科医师肩关节评估表评分从 51.6±6.4 显著提高至 89.3±5.2（t=22.859，P<0.01）。此外，加州大学洛杉矶分校评分从术前的 17.8±3.5 提高至 32.3±1.4（t=19.233，P<0.01）。
关节镜下采用穿线套圈固定修复是一种治疗部分关节突上冈肌腱撕脱的新的腱内技术。该方法保留了肌腱的完整性，可能导致功能改善。总之，穿线套圈固定技术是一种有效的治疗方法。
