Patients undergoing hip arthroscopy who have a diagnosis of rheumatoid arthritis (RA) had less improvement in patient-reported outcomes (PRO) and visual analog scale (VAS) scores and were less satisfied than a matched control group of patients without RA at a minimum 2-year follow-up, according to a recent study. Data were prospectively collected on all hip arthroscopies performed from 2009-2013. Patients with at least 2 years of follow-up and preoperative RA diagnoses were matched (1:2 ratio) to controls without RA. Researchers found:
- 26 hips in 20 RA patients were matched to a control group of 52 hips in 52 patients.
- At a minimum of 2 years of follow-up, RA patients reported no significant improvements except in the Non-Arthritic Hip Score, whereas the control group significantly improved in all PRO and VAS scores.
- Preoperative PRO and VAS scores between the RA and control groups were not significantly different, but postoperatively, all scores were lower in RA patients at a minimum of 2 years, whether they were taking disease-modifying antirheumatic drugs (DMARDs) or not.
- Patients taking DMARDs showed slightly more improvement in PRO and VAS scores.
