Isolated Hip Arthroscopy Provides Comparable Mid‐ to Long‐Term Outcomes in Borderline Hip Dysplasia and Normal Hips: A Systematic Review and Meta‐analysis

This systematic review and meta-analysis pooled four retrospective cohort studies (478 hips total: 157 with borderline hip dysplasia [BDH], 321 with normal acetabular coverage) undergoing isolated hip arthroscopy for FAIS, with follow-up of 5 to over 10 years. Pooled patient-reported outcomes (modified Harris Hip Score, HOS subscales, pain VAS) showed no statistically significant differences between BDH and control groups, and revision rates (14.0% vs 20.9%, OR 0.61, P=.07) and conversion to hip replacement (1.9% vs 4.7%, OR 0.45, P=.22) were also not significantly different, though the point estimates favored BDH patients numerically.

Why it mattersThis informs surgeons and patients whether borderline dysplastic hips can be safely treated arthroscopically without incurring worse durability compared to normally covered hips, which is a common intraoperative decision point in young active patients with FAIS.

The conclusions are not supported by the reported results.

- ?Given that revision and conversion-to-THA rates were numerically lower (though not statistically significant) in the BDH group, how should surgeons weigh capsular plication and labral preservation techniques when counseling BDH patients about arthroscopy versus periacetabular osteotomy?
- ?Should adjunct radiographic parameters like the FEAR index or femoral version be incorporated into preoperative decision-making for BDH patients even though none of the included studies reported them?
