Both male and female elite athletes have an increased total hip arthroplasty risk compared with the general population, a new study finds.
The study, “Risk of total hip arthroplasty after elite sport: linking 3304 former world-class athletes with the Norwegian Arthroplasty Register,” was published online on December 7, 2022, in The British Journal of Sports Medicine.
“At present, there is no cure for osteoarthritis, but severe hip joint degeneration can require total hip arthroplasty. The literature on osteoarthritis after elite sport is limited,” the researchers wrote.
For the study, the Norway-based research group linked a cohort of former Norwegian world-class athletes which included 1,402 females and 1,902 males, active 1936-2006, to the Norwegian Arthroplasty Register. Total hip arthroplasties were performed between 1987-2020.
The team assessed the total hip arthroplasty risk for different sport disciplines, joint impact categories of sport disciplines, and sex. For reference, the research group used the known corresponding general Norwegian population risk of needing a total hip arthroplasty.
After reviewing their data, the research team found that the study group of former elite athletes at age 75 years had a risk for total hip arthroplasty that was about twice that of the reference group (SIR 2.11, 95% CI 1.82 to 2.40). Total hip arthroplasty risk at age 75 years, the team found, was 11.6% for female athletes and 8.3% for male athletes. SIR was 1.90 (95% CI 1.49 to 2.31) for female and 2.28 (95% CI 1.97 to 2.70) for male athletes.
Among males, the team found that high joint impact sport disciplines were associated with increased risk compared with low-impact sport disciplines (RHR 1.81, 95% CI 1.06 to 3.08, p = 0.029).
