High impact sports reduce durability of hip implants April 27, 2012

French researchers have confirmed that high-impact sport, such as jogging or soccer, increases the risk of total hip arthroplasty mechanical failure, according to a study published in Clinical Orthopaedics and Related Research.

“Since participation in sport is now a reality for a significant number of total hip arthroplasty (THA) patients, surgeons may need to adapt their choices of bearing surfaces in implants to accommodate this growing trend,” the authors wrote.

According to the study abstract, the researchers investigated 843 THAs performed between Sept. 1, 1995 and Dec. 31, 2000, focusing on two cohorts:
- one of 70 patients who engaged in high-impact sports following THA
- one of 140 patients with low-activity levels following THA.

All patients in the study underwent evaluation by two independent observers at a minimum follow-up of 10 years. The researchers then, according to a Springer news release, compared the function, wear rates and lifespan of hip implants between the two cohorts. Patients were also asked to complete sports and quality-of-life questionnaires. According to the study results, mean Hip Osteoarthritis Outcome Score for the high-impact sport group was higher in three of five subscales. Linear wear and the number of revisions were higher in the high-activity sport group.

At 15 years’ follow-up, according to the release, the implant survivorship rate was 80% in the high-impact sport group compared to 94% for the low-activity group. The researchers also found that males had increased wear rate over time, but reasons for this gender difference were unclear, according to the release.
