Predictors for moderate to severe acute postoperative pain after total hip and knee replacement.

Purpose: The ability to identify and focus care to patients at higher risk of moderate to severe postoperative pain should improve analgesia and patient satisfaction, and may affect reimbursement. We undertook this multi-centre cross-sectional study to identify preoperative risk factors for moderate to severe pain after total hip (THR) and knee (TKR) replacement.

Methods: A total of 897 patients were identified from electronic medical records.

A cross-sectional survey on prevalence and risk factors for persistent postsurgical pain 1 year after total hip and knee replacement.

Background And Objectives: There is a paucity of large multi-institutional surveys to determine the prevalence of and risk factors for persistent pain after total hip (THR) and knee (TKR) replacements. We surveyed a variety of practices and patients and also correlated persistent pain with health-related quality-of-life outcomes.

Methods: From October 10, 2007, to March 15, 2010, patients who had undergone primary THR or TKR with a minimum follow-up of 1 year were identified.
