AI simplified

Abstract

At 6 years, 58% of patients with hip and knee did not undergo joint replacement surgery.

  • Patients with hip osteoarthritis had an 86% increased risk of requiring surgery compared to knee osteoarthritis patients.
  • 67% of knee osteoarthritis patients did not need knee replacement surgery by the 6-year mark.
  • 40% of hip osteoarthritis patients did not undergo surgery at the same time point.
  • A significant number of both hip and knee osteoarthritis patients may benefit from conservative therapy.
