Background
This study aims to evaluate the long-term outcomes of hip arthroscopy in patients over 50 years old, particularly focusing on the risk factors for conversion to total hip arthroplasty (THA).
Methods
The study followed 94 patients (91.3% follow-up rate) who underwent hip arthroscopy for labral tears and femoroacetabular impingement (FAI). Patient-reported outcomes (PROs) were collected, and risk factors for requiring THA were assessed.
Key Findings
At a mean follow-up of 70.1 months, patients showed significant improvement in all PROs, with 54.3% achieving the patient-acceptable symptomatic state for modified Harris Hip Score (mHHS). However, 4.3% required secondary arthroscopy, and 4.3% required conversion to THA. Risk factors for conversion to THA included higher body mass index, larger alpha angles, and higher grade osteoarthritis.
Conclusions
Hip arthroscopy can lead to significant improvements in PROs in patients over 50. However, there is a risk of needing THA, particularly for those with higher BMI, more severe osteoarthritis, and certain hip morphology.
What Does This Mean for Patients
Patients over 50 considering hip arthroscopy should be aware of the potential for conversion to THA, though many will experience significant improvement in symptoms.
