Abstract：
OBJECTIVE: This study aimed to investigate the efficacy of arthroscopic subacromial balloon placement for massive rotator cuff tear (MRCT), assessing patient satisfaction, outcomes, shoulder functionality, pain scores, and revision-free survivorship up to eight years post the initial surgery.
METHODS: In this retrospective study with prospective data collection, patients with MRCTs undergoing balloon placement from 2014 to 2017 were prospectively enrolled. Their outcomes were analyzed retrospectively over a minimum 5-year follow-up. Demographics, patient satisfaction, reoperations, and complications were documented. Minimal clinically important differences (MCIDs) were calculated for SF-12 scores and Constant-Murley score (CMS) sub-scores. Pre- and post-surgery measures statistically compared for anatomical and functional evaluations.
RESULTS: In a study with 61 participants initially, 10 were lost to follow-up over 3 years. Of the remaining 51, 9 were lost at the latest follow-up. The cohort (42 participants, mean age 63.17 ± 7.66 years) was monitored for 83.98 ± 9.50 months. Seven participants required revisions within two years, resulting in an 83.33% revision-free survival rate. Significant improvements were observed from preoperative to latest follow-up: acromiohumeral interval decreased (7.83 to 6.56, p = 0.004), critical shoulder angle increased (36.10 to 38.24, p = 0.001), osteoarthritis grade increased (1.45 to 2.81, p = 0.001), SF-12 physical score improved (27.40 to 37.69, p = 0.001), and Constant-Murley total scores increased (26.50 to 68.69, p = 0.001). MCID for total Constant-Murley scores was 11.78 points. Among those without revisions, satisfaction rates were 11.43% excellent, 57.14% satisfied, and 31.43% dissatisfied.
CONCLUSIONS: Employing a balloon spacer for MRCTs yielded moderate satisfaction at the 5-year follow-up, with stable revision rates within the first 2 years. Notably, low revision surgery rates, high revision-free survival, and significant shoulder functionality improvements were observed at a minimum 5-year follow-up with arthroscopic subacromial balloon placement in conjunction with biceps tenotomy and subacromial bursectomy for MRCT.

摘要：
目的：本研究旨在探讨关节镜下肩峰下球囊置入治疗肩袖大面积撕裂（MRCT）的疗效，评估患者满意度，结果，肩部功能，疼痛评分,首次手术后8年的免修正生存率。
方法：在这项前瞻性数据收集的回顾性研究中，前瞻性纳入2014~2017年接受球囊置入的MRCT患者.在至少5年的随访中对其结果进行回顾性分析。人口统计,患者满意度,重新操作,并记录了并发症。计算SF-12评分和Constant-Murley评分(CMS)子评分的最小临床重要差异(MCID)。手术前和手术后的测量进行统计学比较，以进行解剖和功能评估。
结果：在一项最初有61名参与者的研究中，10人在3年内失去随访。在剩下的51人中，有9人在最新的后续行动中丢失了。队列(42名参与者，平均年龄63.17±7.66岁)监测83.98±9.50个月。七名与会者要求在两年内进行修订，导致83.33%的无修订生存率。从术前到最近的随访观察到显著的改善：肩眼肱骨间隔减少（7.83至6.56，p=0.004），临界肩角增加（36.10至38.24，p=0.001），骨关节炎等级增加（1.45至2.81，p=0.001），SF-12体质评分提高（27.40至37.69，p=0.001），Constant-Murley总分增加（26.50至68.69，p=0.001）。Constant-Murley总得分的MCID为11.78分。在那些没有修订的人中，满意率为11.43%，57.14%满意，31.43%的人不满意。
结论：在5年的随访中，使用球囊垫片进行MRCT可获得中等满意度，在头两年内具有稳定的修订率。值得注意的是,低翻修手术率，高无修订生存，在至少5年的随访中，通过关节镜下肩峰下球囊置入术，并结合二头肌肌腱切开术和肩峰下滑囊切除术进行MRCT，观察到肩部功能显着改善。
