Researchers examined 709 former elite male athletes with a median age of 70 years old who had been retired from professional sports for an average of 35 years. Their data was compared with data from a control group of 1,368 non-professional athletes.
The risk for osteoarthritis and prevalence of joint arthroplasty was higher among the former athletes. The former athletes had twice the risk of hip osteoarthritis and 2.5 times higher risk of hip arthroplasty. Knee osteoarthritis, which was also higher among the former athletes, was associated with knee injury.
