HIGH-IMPACT ACTIVITY MAY INCREASE WEAR ON ARTIFICIAL HIPS.

HIGH-IMPACT ACTIVITY MAY INCREASE WEAR ON ARTIFICIAL HIPS.

High-impact sports are associated with increased wear and reduced implant durability after total hip arthroplasty (THA), according to a study published online in the journal Clinical Orthopaedics and Related Research. The authors retrospectively identified 70 patients who engaged in high-impact sports and 140 with low activity levels from among 843 THA patients from a prospectively collected database. At 10-year follow-up, they found that mean Hip Osteoarthritis Outcome Score (HOOS) was higher in the high-impact group for three of five subscales. In addition, mean linear wear was higher in the high-impact group than in the low-activities group, and the likelihood of revision was greater among patients in the high-activity group.
