Background:

Recently, a hypertrophic labrum has been reported in the absence of hip dysplasia, which can possibly contribute to an acetabular labral tear.

Purpose:

To compare the clinical outcomes and complications, including the incidence of iatrogenic acetabular labrum and cartilage injury, in patients with tears of hypertrophic versus morphologically normal acetabular labra over a minimum follow-up period of 2 years and to assess the morphologic changes at follow-up computed tomography arthrography in the 2 groups.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Between January 2010 and December 2016, 20 patients (22 hips) with a hypertrophic labrum underwent arthroscopic hip surgery. A total of 22 patients (22 hips) without a hypertrophic labrum were assigned to the control group based on matching criteria, including age, sex, body mass index, labral tear, and labral repair. Clinical outcomes were assessed with the visual analog scale score, UCLA activity scale score (University of California, Los Angeles), and modified Harris Hip Score. Radiologic outcomes were assessed through serial radiography. Patients were followed for at least 2 years.

Results:

The mean age at surgery was 42 years. The most common cause of arthroscopic surgery in the study group was an isolated acetabular labral tear without any bony structural abnormalities (68.2%, 15 of 22 hips). All improvements in both groups were statistically significant at the last postoperative follow-up (P < .001). Although the radiologic and clinical outcomes were not significantly different between the groups, the complication rates, including iatrogenic labral perforations and cartilage injury, were significantly higher in patients with hypertrophic acetabular labral tears (9 vs 3, P = .042). The patient-reported satisfaction scores at the last postoperative follow-up were 8.4 and 7.9 in the study and control groups, respectively (P = .351).

Conclusion:

The high rates of patient-reported satisfaction and the clinical outcomes after arthroscopic repair in both groups are encouraging. Arthroscopic treatment in patients with hypertrophic acetabular labral tears should be carefully performed to prevent iatrogenic injury during the surgery, and isolated hypertrophic labral tears can have good results after repair.

肥厚性眼泪与形态学正常的髋臼拉布拉患者的关节镜修复后的结果。

背景：

最近，在没有髋关节发育异常的情况下，出现了肥厚的唇rum，这可能导致髋臼唇裂。

目的：

在至少两年的随访期内，比较肥厚性与形态正常的髋臼la裂患者的临床结果和并发症（包括医源性髋臼唇和软骨损伤的发生率），并评估随访时的形态变化两组均采用计算机体层摄影术。

学习规划：

队列研究；证据水平3。

方法：

在2010年1月至2016年12月之间，对20例（22髋）肥厚性唇rum患者进行了关节镜下髋关节手术。根据匹配标准，包括年龄，性别，体重指数，阴唇撕裂和阴唇修复，将22例无肥厚唇的患者（22髋）分配到对照组。用视觉模拟量表评分，UCLA活动量表评分（加利福尼亚大学洛杉矶分校）和改良的Harris髋关节评分评估临床结局。放射学结果通过连续放射线照相术进行评估。随访患者至少2年。

结果：

手术的平均年龄为42岁。在研究组中，关节镜手术最常见的原因是孤立的髋臼唇撕裂，没有任何骨结构异常（68.2％，22髋中的15髋）。在最后一次术后随访中，两组的所有改善均具有统计学意义（P <.001）。尽管两组间的放射学和临床结局无显着差异，但肥厚性髋臼唇撕裂患者的并发症发生率（包括医源性唇穿孔和软骨损伤）明显更高（9 vs 3，P = .042）。研究组和对照组患者最后一次随访时患者报告的满意度得分分别为8.4和7.9（P = .351）。

结论：

两组中患者报告的满意率和关节镜修复后的临床结果均令人鼓舞。肥大的髋臼唇泪的关节镜治疗应谨慎进行，以防止手术期间的医源性损伤，孤立的肥大的唇泪修复后可取得良好的效果。
