Abstract：
BACKGROUND: Posterior shoulder instability makes up approximately 10% of all shoulder instability cases and its diagnosis and treatment is less well understood. Recently, however, there has been increased recognition of posterior instability and posterior stabilization. The purpose of this study was to systematically review the literature to ascertain the outcomes on arthroscopic stabilization of posterior shoulder instability.
METHODS: Two independent reviewers conducted a systematic literature search based on PRISMA guidelines, utilizing the MEDLINE database. Studies were eligible for inclusion if they reported postoperative outcomes for posterior shoulder instability following arthroscopic stabilization.
RESULTS: A total of 48 studies met inclusion criteria for review including 2307 shoulders. Majority of patients were male (83.3%), with an average age of 26.1 years and a mean follow-up of 46.8 months. The functional outcome score primarily utilized for postoperative assessment was ASES with an average of 84.77. Overall, 90.9% of patients reported being satisfied with their arthroscopic stabilization. Recurrent instability occurred in 7.4% of patients. The total revision rate was 5.2%. 16.6% of patients reported residual pain postoperatively. The rate of return to play was 86.4% with 68.0% of patients returning to play at the same or higher level of play.
CONCLUSIONS: Arthroscopic stabilization of posterior shoulder instability resulted in good outcomes with high patient satisfaction and low rates of recurrent instability, revisions, and residual pain.

摘要：
背景：肩后不稳定约占所有肩关节不稳定病例的10％，对其诊断和治疗的了解较少。最近,然而,对后部不稳定和后部稳定的认识有所增加。这项研究的目的是系统地回顾文献，以确定关节镜稳定后肩关节不稳定的结果。
方法：两名独立审稿人根据PRISMA指南进行了系统的文献检索，利用MEDLINE数据库。如果研究报告了关节镜稳定后肩后不稳定的术后结果，则有资格纳入研究。
结果：共有48项研究符合纳入标准，包括2307项。大多数患者为男性（83.3%），平均年龄26.1岁，平均随访46.8个月。主要用于术后评估的功能结局评分为ASES，平均为84.77。总的来说,90.9%的患者报告对他们的关节镜稳定感到满意。7.4%的患者出现复发性不稳定。总修订率为5.2%。16.6%的患者报告术后残留疼痛。比赛的恢复率为86.4％，其中68.0％的患者以相同或更高的比赛水平恢复比赛。
结论：关节镜下稳定治疗后肩关节不稳的结果良好，患者满意度高，不稳复发率低。修订,和残余的疼痛。
