The objective of this study was to evaluate the functional outcome during follow-up (FU) after endoscopic tenotomy for iliopsoas (IP)-cup impingement and to quantitatively analyze the hip flexion strength.
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.
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.
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.

本研究旨在评估内镜下髂腰肌（IP）-杯撞击症切开术后的随访（FU）期间的功能结果，并对髋关节屈曲力量进行定量分析。
这是一项由单中心、回顾性队列研究的单一外科医生系列研究。功能评估基于改良 Harris 评分、牛津评分和视觉模拟评分。在坐姿和仰卧位使用手持测力计测量力量。
2013 年 5 月至 2021 年 11 月期间，对 36 例 IP 切开术治疗杯撞击症进行了治疗。7 例（19%）患者失访。切开术时，平均（标准差）年龄为 62.6（12.2）岁，BMI 为 26.5（4.1）。切开术后至最后一次 FU 的平均 FU 时间为 3.6（0.8）年。所有三个结局评分均从术前改善到术后 6 个月（p < 0.001）。从 6 个月到最后一次 FU 没有显著变化。改良 Harris 评分的最小临床重要差异（MCID）设定为 25。20（69%）例患者在一个月和六个月时的数值超过了阈值，19 例（65.5%）在最后一次 FU 时的数值超过了阈值，呈现中性。髋关节屈曲力量的跛行对称指数在最后一次 FU 时为 90°时为 63%，30°时为 40%。
大多数患者在接受内镜下髂腰肌切开术后，其结局评分显著改善，且结果随着时间的推移保持稳定。尽管髋关节屈曲力量显著下降，但大多数患者并未报告生活质量受损。
