Abstract：
BACKGROUND: Os acetabuli (OSA) is defined as a radiopaque structure located around the acetabular rim highly related to Femoroacetabular Impingement (FAI). Its treatment depends on the perspective of post-surgical joint instability. Ossicle resection is recommended if the femoral head is covered enough by the labrum. Previous research has described the results of this technique in general population. The aim of this study is to describe the outcomes and the time and rate of return to play (RTP) after hip arthroscopy and OSA removal in soccer players.
METHODS: This study is a retrospective analysis of a prospective database containing all the consecutive soccer players who had undergone hip arthroscopy between 2018 and 2019. The subjects diagnosed with OSA and a center-edge angle (CEA) > 25 ° were included in the analysis. All the patients were treated with arthroscopic removal of the OSA and femoral osteoplasty. Hip function was assessed using the Modified Harris Hip Score (MHHS) before and at 3 and 12 months after surgery. Rate of RTP and competitive level at RTP were assessed at a 1-year follow-up.
RESULTS: Between 2018 and 2019, 90 soccer players were treated with hip arthroscopy in our facilities. Six of them (6.6%) were diagnosed with OSA. Mean (SD) MHHS values were 69.7 (12.1) before the surgery, 89.7 (6.7) at 3 months post-surgery and 95.7 (5.1) at 12 months post-surgery. All the subjects reported significant improvements in their MHHS scores at 3 and 12 months post-surgery compared with pre-surgery levels (p < 0.01). Non-significant differences were found between 3 and 12 months post-surgery (p > 0.05). All the subjects (100%) returned to previous competitive levels.
CONCLUSIONS: After surgery, all the soccer players returned to previous competitive level. Preoperative MHHS improved significantly at 3 months maintained for up to 12 months.

摘要：
背景：髋臼（OSA）被定义为位于髋臼边缘周围与股骨髋臼撞击（FAI）高度相关的不透射线结构。其治疗取决于手术后关节不稳定的观点。如果股骨头被唇覆盖足够多，建议切除小骨。先前的研究已经描述了这种技术在普通人群中的结果。这项研究的目的是描述足球运动员髋关节镜检查和OSA去除后的结果以及恢复比赛（RTP）的时间和速度。
方法：本研究是对前瞻性数据库的回顾性分析，该数据库包含2018年至2019年期间接受髋关节镜检查的所有连续足球运动员。分析中包括诊断为OSA和中心边缘角(CEA)>25°的受试者。所有患者均接受关节镜下OSA去除和股骨骨成形术治疗。在手术前以及手术后3个月和12个月时，使用改良的Harris髋关节评分（MHHS）评估髋关节功能。在1年的随访中评估RTP的比率和RTP的竞争水平。
结果：在2018年至2019年之间，90名足球运动员在我们的设施中接受了髋关节镜检查。其中6人（6.6%）被诊断为OSA。术前MHHS平均值（SD）为69.7（12.1），手术后3个月为89.7（6.7），手术后12个月为95.7（5.1）。所有受试者在手术后3个月和12个月的MHHS评分与手术前水平相比显著改善(p<0.01)。术后3至12个月间无显著性差异(p>0.05)。所有科目（100％）恢复到以前的竞争水平。
结论：手术后，所有足球运动员都恢复到以前的竞技水平。术前MHHS改善显著，3个月维持长达12个月。
