Although most patients undergoing hip arthroscopy do not require an ipsilateral total hip arthroplasty, recently published results showed hip arthroscopy failures occur relatively soon following the procedure.
Researchers reviewed the Humana administrative claims data from 2007 to 2014 and identified 1,577 patients (63% were women) who underwent hip arthroscopy. Researchers tracked patients to determine the rates and timing of subsequent ipsilateral total hip arthroplasty (THA).
Results showed 5.3% of patients underwent ipsilateral THA after hip arthroscopy during the follow-up period. Researchers found 49.3% of patients underwent chondroplasty during index hip arthroscopy and 37.5% of patients who underwent hip arthroscopy had a preoperative diagnosis of osteoarthritis (OA) of the hip.
Overall, 8.2% of patients who underwent chondroplasty and 9.7% of patients with OA required a conversion to THA compared with 2.5% of patients who did not undergo chondroplasty and 2.7% of patients without OA. Patients aged 50 years or older experienced a significantly higher odds of conversion to THA vs. patients younger than 50 years, researchers noted.
All subsequent THAs occurred within 48 months of the initial hip arthroscopy, according to an analysis of time to a THA after hip arthroscopy. Of these cases, 35.7% occurred within 6 months; 60.7% occurred within 12 months; and 83.3% occurred within 18 months after index arthroscopic procedure. – by Casey Tingle
