Purpose
To report clinical outcomes in patients with borderline dysplasia undergoing arthroscopic labral seal restoration with minimal acetabular rim resection and capsular plication.
Methods
Patients <40 years with lateral center-edge angle 18°–25°, minimum 2-year follow-up after arthroscopic treatment including ≤2 mm rim resection and capsular plication. Excluded Tönnis grade ≥1, center-edge angle ≤17°, and Legg-Calvé-Perthes disease. PROs collected: mHHS, Non-Arthritic Hip Score, HOS-ADL, HOS-SSS, VAS, satisfaction, complications, and revisions.
Key Findings
55 procedures followed up; labrum repaired/debrided/reconstructed in 37/17/1 cases. Significant improvements in all PROs and VAS; mean patient satisfaction 8.09. 11% needed revision surgery.
Conclusions
Arthroscopic minimal rim resection with labral restoration and capsular plication improves outcomes in borderline dysplasia patients not requiring osteotomy.
What Does This Mean For Patients
Patients with borderline hip dysplasia can expect significant symptom improvement and good satisfaction with this minimally invasive arthroscopic procedure, though some may need further surgery.
