Objective
To compare patient-reported outcomes (PROMs) after hip arthroscopy versus periacetabular osteotomy (PAO) in the treatment of borderline hip dysplasia (BHD).
Methodology
This systematic review analyzed 26 studies (8 PAO, 18 arthroscopy) published after 2014, focusing on radiographic data, operative findings, and PROMs.
Key Findings
- Both treatment groups showed significant improvement in outcomes.
- Arthroscopy studies reported higher alpha angles, suggesting more cam-type morphology.
- Modified Harris Hip Score improvements ranged from 20–29 (PAO) and 17.9–34.4 (arthroscopy).
- Considerable heterogeneity between studies limited direct comparisons.
Conclusion
Both PAO and arthroscopy are effective for treating BHD. Patient selection and deformity type, such as cam morphology, may help guide surgical choice.
What Does This Mean For Patients
If you have borderline hip dysplasia, both hip arthroscopy and PAO can improve your symptoms. Your surgeon will help decide which surgery is best for you based on your specific hip condition.
