Background
Predicting long-term clinical outcomes following hip arthroscopy remains challenging due to multiple influencing factors.
Methods
Retrospective analysis of 1,038 patients undergoing hip arthroscopy from 2008 to 2012, with 5-year follow-up using PROs including Nonarthritic Hip Score (NAHS) and mHHS.
Key Findings
Seven significant predictors of 5-year outcomes were identified:
- Preoperative NAHS
- Body mass index (BMI)
- Age
- Joint space width
- Alpha angle
- Revision surgery status
- Acetabular microfracture procedure
Factors associated with eventual total hip replacement included:
- Increased age
- Higher BMI
- History of revision surgery
- Femoral cartilage damage
Conclusions
These predictors can assist providers in risk stratification and prognostication for patients undergoing hip arthroscopy.
What Does This Mean for Providers?
Preoperative assessment should incorporate these predictors to optimize patient selection, manage expectations, and inform postoperative planning. Awareness of these factors enables targeted counseling regarding prognosis and risk of progression to hip arthroplasty.
