Background
Hip arthroscopy in patients with borderline dysplasia is controversial due to concerns over joint stability and long-term success.
Methods: This study followed 24 patients (25 hips) with borderline dysplasia (lateral center-edge angle 18–25°) treated with labral preservation and capsular plication during hip arthroscopy. Patients had a minimum 5-year follow-up and no prior hip surgery or severe dysplasia.
Key Findings
At an average of 68.8 months, all PROs (mHHS, NAHS, HOS-SSS, VAS) showed statistically significant improvements. Four hips (19%) required revision arthroscopy, but none were converted to total hip arthroplasty.
Conclusions
In well-selected patients, hip arthroscopy with labral preservation and capsular plication offers safe and lasting outcomes in the setting of borderline dysplasia.
What Does This Mean for Patients
For those with mild structural hip instability, arthroscopic treatment may provide long-term relief and improved function—if performed by experienced surgeons with careful attention to stabilizing the labrum and capsule.
