Study finds, Total Hip Arthroplasty After Hip Arthroscopy Ha
There has been an increase in hip arthroscopy (HA) over the last decade. Following HA, some patients may ultimately require a total hip arthroplasty (THA).

The Pearl Diver Research Program was queried to capture all the patients undergoing THA. Propensity matching was performed to match THA patients with and without a history of ipsilateral THA. Rates of 30-day medical complications, 1 year surgical complications, and THA revision were compared using multivariate logistic regression.

--Following propensity matching, cohorts of 1940 patients undergoing THA without prior HA and 1940 patients undergoing a THA with prior HA were isolated for analysis.

--The mean time from HA to THA was 1127 days. Patients with a history of ipsilateral HA had an increased risk for dislocation (OR 1.56) and overall decreased implant survival within 4 years of undergoing THA (OR 1.53).

--Furthermore, this data demonstrates the timing of previous HA to be associated with the risk of complications, as illustrated by the increased risk for dislocation (OR 1.75), aseptic loosening (OR 2.18) and revision surgery at 2 (OR 1.92) and 4 years (OR 2.05) in patients undergoing THA within 1 year of HA compared to patients undergoing THA more than 1 year following HA or with no previous history of HA.

In conclusion, patients who receive THA after HA are at a higher risk of surgical complications and the need for revision surgery.
