Background:

Active-duty servicemembers are a population at risk for the development of posterior shoulder instability. While short-term outcomes after arthroscopic posterior labral repair for posterior shoulder instability are promising, there is a paucity of longer term follow-up data for this procedure.

Purposes:

The primary purpose was to report midterm outcomes after arthroscopic posterior labral repair in active-duty military patients for posterior shoulder instability without bone loss. The secondary purpose was to determine if outcomes varied between anchor types used.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Preoperative and postoperative outcomes, with a minimum 3-year follow-up, for a visual analog scale for pain, the Single Assessment Numeric Evaluation (SANE), the American Shoulder and Elbow Surgeons (ASES) score, and the Rowe score were collected and analyzed. A separate subgroup analysis was performed comparing the outcomes of patients who underwent repair with biocomposite anchors versus those who underwent repair with all-suture anchors.

Results:

A total of 73 patients with a mean follow-up of 82.55 ± 24.20 months met the inclusion criteria and were available for analysis. As a whole, the cohort demonstrated statistically and clinically significant improvements in outcome scores at final follow-up. Preoperative and postoperative range of motion did not vary significantly. While the difference in final outcome scores between the 2 anchor types did not reach statistical significance, a statistically significantly larger proportion of patients who underwent repair with all-suture anchors versus those who underwent repair with biocomposite anchors met the Patient Acceptable Symptom State for the SANE (97.14% vs 78.95%, respectively; P = .0180) and the ASES score (88.57% vs 68.42%, respectively; P = .0171). The proportion of patients who achieved the substantial clinical benefit or surpassed the minimal clinically important difference, however, did not vary by anchor type. Overall, 70 patients (95.89%) remained on active duty and were able to return to preinjury work and recreational activity levels. There were 3 patients (4.11%) who had recurrent posterior instability.

Conclusion:

This population of active-duty servicemembers undergoing posterior labral repair for posterior labral instability without bone loss demonstrated a statistically and clinically significant improvement in midterm outcomes, a low recurrence rate, and a rate of return to active duty of 95.89%, regardless of the anchor type used.

现役军人患者的关节镜后盂唇修复：无论锚钉类型如何，为高危人群提供可靠的解决方案

背景：

现役军人是有发生肩后部不稳定风险的人群。虽然关节镜后盂唇修复后肩部不稳定的短期结果是有希望的，但该手术的长期随访数据很少。

目的：

主要目的是报告现役军人肩关节后部不稳定关节镜下盂唇修复后无骨质流失的中期结果。次要目的是确定使用的锚类型之间的结果是否不同。

学习规划：

队列研究；证据水平，3。

方法：

术前和术后结果，至少 3 年的随访，针对疼痛的视觉模拟量表、单一评估数值评估 (SANE)、美国肩肘外科医生 (ASES) 评分和 Rowe 评分进行收集和分析了。进行了单独的亚组分析，比较了接受生物复合锚钉修复的患者与接受全缝合锚钉修复的患者的结果。

结果：

共有 73 名患者，平均随访时间为 82.55 ± 24.20 个月，符合纳入标准并可进行分析。总体而言，该队列在最终随访时的结果评分在统计学和临床​​上都有显着改善。术前和术后的活动范围没有显着变化。虽然两种锚钉类型之间最终结果评分的差异没有达到统计学意义，但在统计学上，接受全缝合锚钉修复的患者与接受生物复合锚钉修复的患者相比，符合 SANE 的患者可接受症状状态的比例显着增加（分别为 97.14% 和 78.95%；P = .0180）和 ASES 评分（分别为 88.57% 和 68.42%；P= .0171)。然而，获得显着临床益处或超过最小临床重要差异的患者比例并没有因锚定类型而异。总体而言，70 名患者 (95.89%) 仍处于现役状态，并且能够恢复到受伤前的工作和娱乐活动水平。有3名患者（4.11%）有复发性后路不稳。

结论：

这群现役军人因后盂唇不稳而接受后盂唇修复而没有骨质流失，在中期结果方面表现出统计学和临床​​上的显着改善、低复发率和 95.89% 的现役恢复率，无论锚定如何使用的类型。
