In nonarthritic patients with femoroacetabular impingement syndrome, borderline dysplasia, and symptomatic iliopsoas snapping, arthroscopic iliopsoas fractional lengthening carries a significant risk of postarthroscopic instability. The iliopsoas is a dynamic stabilizer of the anterior hip. Thus, although statistically significant and clinically important improvements in hip function have the potential to be achieved with iliopsoas fractional lengthening, surgeons must be supremely confident in their ability to perform a secure capsular plication, labral preservation (not debridement), comprehensive cam correction, avoidance of intra-abdominal fluid extravasation, release of all iliopsoas tendon bands (if bifid or trifid), and ensure that femoral version is normal or low, neck-shaft angle is not excessively valgus, the dysplasia magnitude is no more than mild, and that there is no excessive soft tissue hypermobility. If these goals can be met, then excellent outcomes can be achieved. If not, then an iliopsoas fractional lengthening should not be performed.
在非关节炎性股骨髋臼撞击综合征患者中，边缘性髋臼发育不良和症状性髂腰肌弹响，如果进行关节镜下髂腰肌部分松解术，存在显著的术后关节镜下不稳定风险。髂腰肌是髋关节前方的动态稳定结构。因此，尽管关节镜下髂腰肌部分松解术在改善髋关节功能方面具有统计学意义和临床重要性，但外科医生必须对自己进行安全的囊袋紧缩、盂唇保留（而非清创）、全面的凸轮畸形矫正、避免腹腔内液体渗出、松解所有髂腰肌肌腱束（如果存在分叉或三叉），以及确保股骨颈干角正常或轻度外翻、髋臼发育不良程度不超过轻度、且不存在过度软组织松弛的能力有绝对信心。如果能够达到这些目标，那么可以获得优异的疗效。如果不能，那么不应进行髂腰肌部分松解术。
