Abstract：
BACKGROUND: Hip instability following arthroscopy is a rare complication with a clinical spectrum ranging from gross dislocation (macro-instability) to micro-instability, characterized by pain and limitation for daily activities. Therefore, it should be considered as a potential differential diagnosis in patients experiencing persistent pain after hip arthroscopy.
METHODS: A 41-year-old male presented with a history of anterior hip dislocation and macro-instability symptoms three years post-hip arthroscopy. Magnetic resonance imaging (MRI) revealed a disruption of the anterior hip capsule. The patient initiated physiotherapy and resumed activities, but ten months later, experienced another anterior dislocation. Pain and apprehension during external hip rotation were evident. Three-dimensional computed tomography (CT) indicated irregularities in the anterior and superior margin of the acetabulum, while MRI arthrogram showed a rupture of the anterior capsule and deficiency in the anterior hip ligaments. Open reconstruction of the anterior capsule was performed, resulting in favorable progression over the 5-year follow-up.
CONCLUSIONS: This case highlights post-arthroscopy hip instability with a delayed presentation, possibly linked to chronic anterior capsule deficiency and inadequate acetabular coverage. Primary capsule repair after hip arthroscopy has proven effective in reducing the occurrence of instability symptoms and reoperations.
CONCLUSIONS: Post-arthroscopic hip instability may manifest immediately after surgery or several years later. Open reconstruction of the anterior capsule emerges as a successful strategy for addressing this complication, demonstrating satisfactory outcomes in a 5-year follow-up.

摘要：
背景：关节镜检查后髋关节不稳定是一种罕见的并发症，临床范围从总体脱位（宏观不稳定）到微观不稳定，以疼痛和日常活动受限为特征。因此,对于髋关节镜检查后持续疼痛的患者，应将其视为潜在的鉴别诊断。
方法：一名41岁男性患者，在髋关节镜检查3年后有前髋关节脱位和宏观不稳定症状。磁共振成像（MRI）显示前髋关节囊破裂。患者开始物理治疗并恢复活动，但十个月后,经历了另一次前脱位。外髋关节旋转过程中的疼痛和忧虑是明显的。三维计算机断层扫描（CT）显示髋臼前缘和上缘不规则，而MRI关节造影显示前囊破裂和前髋关节韧带不足。进行了前囊的开放性重建，在5年的随访中取得了良好的进展。
结论：此病例突出显示关节镜术后髋关节不稳定，延迟表现，可能与慢性前囊不足和髋臼覆盖不足有关。髋关节镜检查后的初次胶囊修复已被证明可有效减少不稳定症状和再次手术的发生。
结论：关节镜术后髋关节不稳定可能在手术后立即出现或几年后出现。前囊的开放重建是解决这种并发症的成功策略。在5年的随访中显示令人满意的结果.
