METHODS: This was a monocentric, retrospective cohort study of a single surgeon series. Functional assessment was based on the modified Harris score, the Oxford score and the visual analog scale score. Strength was measured with a handheld dynamometer in the sitting and lying position.
RESULTS: Thirty-six IP tenotomies for cup impingement were performed between May 2013 and November 2021. Seven (19%) patients were lost to FU. At the time of tenotomy, the mean (standard deviation) age was 62,6 (12,2) and BMI was 26,5 (4,1). The mean FU time after tenotomy to the last FU was 3,6 (0,8) years. All three outcome scores improved from preoperatively to six months postoperatively (p < 0.001). There were no significant change from six months to last FU. The minimal clinically important difference (MCID) of the modified Harris score was set at 25. 20 (69%) patients had values that exceeded the threshold at one month and six months and neutral 19 (65.5%) had values that exceeded the threshold at the last FU. The limp symmetry index concerning hip flexion strength was 63% at 90° and 40% at 30° at the last FU.
CONCLUSIONS: Most patients significantly improved their outcome scores after endoscopic iliopsoas tenotomy, with results remaining consistently stable over time. Despite a significant loss in hip flexion strength, the majority of patients did not report any impairment of their quality of life.
METHODS: Level III, Retrospective cohort study.
方法:这是一个单中心,单外科医生系列的回顾性队列研究。功能评估基于改良的Harris评分,牛津得分和视觉模拟量表得分。用手持测力计在坐姿和卧姿测量强度。
结果:在2013年5月至2021年11月期间,进行了36次IP肌腱切开术,用于杯撞击。7名(19%)患者失去了FU。在肌腱切开术的时候,平均(标准差)年龄为62,6(12,2),BMI为26,5(4,1).肌腱切开术后至最后一次FU的平均FU时间为3,6(0,8)年。所有三个结果评分从术前到术后6个月都有所改善(p<0.001)。从六个月到上次FU没有重大变化。将改良的Harris评分的最小临床重要差异(MCID)设定为25。20例(69%)患者在1个月和6个月时的值超过阈值,而中性19例(65.5%)的值在最后一次FU时超过阈值。在最后一个FU,有关髋关节屈曲强度的跛行对称指数在90°为63%,在30°为40%。
结论:大多数患者经内镜髂腰肌肌腱切开术后的结果评分显著改善,结果随着时间的推移保持稳定。尽管髋部屈曲力量显著下降,大多数患者未报告生活质量有任何损害.
方法:三级,回顾性队列研究。
