Background
Revision hip arthroscopy for patients with borderline hip dysplasia (a condition where the hip socket is slightly shallower than normal) is controversial, with limited studies on its long-term outcomes.
Methods
This study examined patients with borderline dysplasia who underwent revision hip arthroscopy, comparing their results with those of a control group without dysplasia. The primary outcomes were patient-reported hip scores and pain levels at a minimum of 2 years after surgery.
Key Findings
Both groups showed significant improvement in hip scores and pain levels.
The borderline dysplasia group achieved minimal clinically important differences (MCID) for the modified Harris Hip Score (mHHS) at a rate of 70%.
The rate of conversion to total hip arthroplasty (THA) was higher in the borderline dysplasia group (23.8%) compared to the control group (7.9%).
Conclusions
Revision hip arthroscopy for borderline dysplasia patients results in significant improvement in hip function and pain. However, the risk of needing a hip replacement is higher in this group.
What Does This Mean for Patients
If you have borderline hip dysplasia and are considering revision arthroscopy, it can improve your hip function, but there is a higher risk of needing further surgery, including a hip replacement.
