The aim of the study was to prospectively evaluate hip muscle strength in a series of patients with symptomatic FAI after hip arthroscopy.
Hip muscle strength of eight patients (age: 29 ± 10 years) was evaluated preoperatively and 2.5 years after hip arthroscopy, and was compared to eight matched controls. Maximal voluntary contraction (MVC) strength was measured for all hip muscle groups. At follow-up, we used the symptom-specific well-being outcome to assess the acceptability of the health state related to the hip.
Patients showed MVC strength increases for all hip muscles (9-59%, P<.05). At follow-up, only hip flexor MVC strength was lower for patients than controls (-18%, P<.05). At follow-up, four patients (out of eight) were "neither satisfied nor dissatisfied" with the health state of their operated hip.
Patients with symptomatic FAI recovered their hip muscle strength to normal levels 2.5 years after hip arthroscopy, except for hip flexors. Although all patients showed good hip muscle strength at follow-up, half of them were not completely satisfied with their health state related to the hip.
本研究旨在对一系列有症状的髋关节撞击综合征（FAI）患者在髋关节镜检查后进行前瞻性的髋部肌肉力量评估。
对8例患者（年龄：29±10岁）在术前及髋关节镜检查后2.5年进行髋部肌肉力量评估，并与8例匹配的对照组进行比较。测量所有髋部肌肉群的最大自主收缩（MVC）力量。在随访时，我们使用症状特异性的健康状况结果来评估与髋关节相关的健康状态的可接受性。
患者所有髋部肌肉的MVC力量均增加（9%-59%，P<0.05）。在随访时，仅患者的髋部屈肌MVC力量低于对照组（-18%，P<0.05）。在随访时，8例患者中有4例对其手术髋关节的健康状态“既不满意也不不满意”。
有症状的FAI患者在髋关节镜检查后2.5年，除髋部屈肌外，其髋部肌肉力量恢复到正常水平。虽然所有患者在随访时显示出良好的髋部肌肉力量，但其中一半对与髋关节相关的健康状态并不完全满意。
