Impact of Total Knee Arthroplasty as Assessed Using Patient‐Reported Pain and Health‐Related Quality of Life Indices: Rheumatoid Arthritis Versus Osteoarthritis

Abstract

TKA is highly effective in reducing clinically relevant knee pain (to a greater extent than its effect on other subjective HRQOL indices in patients with RA), although this improvement is less marked as compared to that among patients with OA. TKA serves as a "time machine" via which patients can return to a lifestyle with less disability, before the arthritis process catches up in RA.
