According to published results, patients who undergo total hip arthroplasty following hip arthroscopy are at increased risk for complications and revision surgery compared with patients who did not have prior hip arthroscopy.
Nicholas J. Lemme MD, and colleagues used the Pearl Diver Research Program to analyze a propensity-matched cohort of 1,940 patients who underwent THA without prior hip arthroscopy (HA) and 1,940 patients who underwent THA with prior HA between 2015 and 2020. Researchers performed multivariate logistic regression to compare 30-day medical complication rates, 1-year surgical complication rates and revision surgery. They also performed Kaplan-Meier analysis to estimate implant survivorship in both groups. Mean time from HA to THA was 1,127 days, according to the study.
Lemme and colleagues found patients who underwent THA with prior ipsilateral HA had an increased risk for dislocation and decreased 4-year implant survivorship. Investigators also found patients who underwent THA within 1 year of HA had an increased risk of dislocation, aseptic loosening and revision surgery at 2 years and 4 years compared with patients who underwent THA more than 1 year after HA and patients with no history of HA.
“Some patients that have undergone a HA may require a THA due to progression of arthritis or femoral head necrosis,” the researchers wrote in the study. “Thus, research related to the effect of prior HA has on the outcomes of patients that undergo future ipsilateral THA is important for patient counselling, selection and perioperative management,” they concluded.
