BACKGROUND & OBJECTIVE

People with osteoarthritis typically undergo joint replacement surgery because of persistent pain that has failed to improve with non-surgical management (e.g. exercise therapy, weight management, injections, etc.) (1). The main reasons patients elect to have a hip or knee replacement are potential improvements in pain and physical function, which are also the most important contributing factors to patient satisfaction following surgery (2,3).

Therefore, the objective of this study was to provide updated estimates of the incidence of long-term pain after total knee and hip replacement and explore factors that may influence the rates observed, in order to help inform patient and clinical decision making.

People with osteoarthritis typically undergo joint replacement surgery because of persistent pain that has failed to improve with non-surgical management.

Patients with osteoarthritis considering joint replacement surgery, should be provided with all the necessary information to weigh the potential benefits and risks of surgery.

METHODS

• The authors conducted a systematic review and meta-analysis synthesizing the latest data on the prevalence of long-term pain in patients who underwent total hip replacement (THR) or total knee replacement (TKR) surgery.
