Purpose

Evaluate the clinical outcomes after arthroscopic treatment of synovial chondromatosis (SC) of the hip.

Materials and Methods

We evaluated patients who underwent arthroscopic management for SC of the hip from November 2008 to March 2017. Radiographic evaluation was made before and after surgery. The modified Harris Hip Score (mHHS), Hip Disability and Osteoarthritis Outcome Score (HOOS), visual analogue scale (VAS) score, and patient self-reported satisfaction were collected and analyzed before and after surgery. Complications and recurrence that occurred after surgery were recorded.

Results

Forty-one patients (27 men and 14 women) were the study cohort. The mHHS improved from 67.0 to 83.7, HOOS-Symptoms improved from 78.8 to 93.3, HOOS-Pain improved from 80.9 to 93.6, HOOS-Activity Limitations–Daily Living improved from 84.5 to 95.1, HOOS-Sport improved from 50.3 to 80.6, and HOOS-Quality of Life improved from 62.2 to 86.7. VAS scores decreased from 3.9 to 1.1. All results demonstrated significant improvement (P < 0.05). Thirty-three (80.5%) patients thought the outcome of surgery was “excellent,” 7 (17.0%) thought it was “good,” 1 (2.4%) thought it was “fair,” and no one thought it was “poor”. Two patients underwent revision surgery.

Conclusion

Hip arthroscopy for SC treatment of the hip showed good clinical results, good satisfaction from patients, and low recurrent prevalence.

关节镜治疗髋关节滑膜软骨瘤病的临床结果

目的

评估关节镜治疗髋关节滑膜软骨瘤病 (SC) 后的临床结果。

材料和方法

我们评估了 2008 年 11 月至 2017 年 3 月期间接受关节镜治疗髋关节 SC 的患者。在手术前后进行了影像学评估。在手术前后收集和分析改良的哈里斯髋关节评分（mHHS）、髋关节残疾和骨关节炎结果评分（HOOS）、视觉模拟评分（VAS）评分和患者自我报告的满意度。记录手术后发生的并发症和复发。

结果

41 名患者（27 名男性和 14 名女性）是研究队列。mHHS 从 67.0 提高到 83.7，HOOS-Symptoms 从 78.8 提高到 93.3，HOOS-Pain 从 80.9 提高到 93.6，HOOS-Activity Limitations-Daily Living 从 84.5 提高到 95.1，HOOS-Sport 从 50.3 提高到 80.6，HOOS - 生活质量从 62.2 提高到 86.7。VAS 分数从 3.9 下降到 1.1。所有结果均显示有显着改善（P < 0.05）。33名（80.5%）患者认为手术结果“极好”，7名（17.0%）认为“好”，1名（2.4%）认为“一般”，没有人认为“差” ”。两名患者接受了翻修手术。

结论

髋关节镜下SC治疗髋关节显示出良好的临床效果，患者满意度高，复发率低。
