Purpose
To evaluate outcomes after hip arthroscopic surgery in patients with mild osteoarthritis (Tönnis grade 1) and compare them with patients without OA (Tönnis grade 0).
Methods
- Matched-pair cohort study with minimum 2-year follow-up.
- Patients matched by age, sex, BMI, labral and capsular treatment.
- Measured patient-reported outcomes (PROs), pain (VAS), satisfaction, revision rates, and conversion to total hip arthroplasty (THA).
Key Findings
- Both groups (Tönnis 0 and 1) showed significant improvement in PROs and pain scores.
- No significant difference in improvement magnitude between groups.
- Revision and THA rates were similar in both groups.
Conclusion
Patients with mild OA (Tönnis 1) benefit from hip arthroscopy with outcomes comparable to those without OA over 2 years.
What This Means for Patients
Patients with early-stage hip arthritis may still expect good results from arthroscopic surgery, with improved function and pain relief similar to patients without arthritis.
