Activity Following Total Hip Arthroplasty: Which Patients Are Active, and Is Being Active Safe?

Abstract

Background: Younger and physically active patients demand a return to sport after total hip arthroplasty (THA). However, because of the risk of implant wear and loosening, high-impact activities are often not recommended. The current study evaluates predictive factors and revision rates in patients with higher activity levels. Methods: This retrospective study included 4152 hips in 3828 patients aged 45–75 that underwent primary THA for primary osteoarthritis between 2009 and 2019 with a minimum follow-up of 2 years. Pain and Lower Extremity Activity Scale (LEAS) were assessed before and 2 years after surgery. Activity was classified as low (LEAS 1–6), moderate (LEAS 7–13), or high (LEAS 14–18). Results: Pain and LEAS improved from preoperative to 2-years postoperative (p p p < 0.001). Conclusions: High physical activity 2 years following THA, with participating in sports like jogging several times a week, did not increase the risk of revision surgery. THA patients should not be prevented from a highly active lifestyle.
