More young adults are developing osteoarthritis—here's how we can spot those at risk before the damage is done

One, a keen marathon runner, developed stage 2 osteoarthritis in her mid-30s. Several well-known public figures, including Robbie Williams, Tiger Woods and Andy Murray, have also spoken openly about experiencing the condition relatively young.
