Objective

To compare 5-year patient-reported outcomes after hip arthroscopy (HA) and periacetabular osteotomy (PAO) for borderline hip dysplasia.

Key Findings

• Both HA and PAO showed similar significant improvements in hip function and pain.
• The PAO group had a longer follow-up but experienced a higher rate of subsequent surgery (mostly hardware removal).
• The revision rate for HA was higher, but not statistically significant compared to PAO.
• No significant difference in conversion to total hip arthroplasty between the two groups.

Conclusion

Both PAO and HA with capsular plication provide similar long-term improvements for patients with borderline hip dysplasia, with low rates of revision surgery.

What Does This Mean For Patients

If you have borderline hip dysplasia, both surgery options could lead to good outcomes. However, PAO may require additional procedures, such as hardware removal, while HA has a slightly higher chance of needing further surgeries.
