Objective: To identify the pain perception and its effect on daily activities among patients with Total Knee Arthroplasty (TKA).
Methods: At the Emergency Department of Queen Alia Hospital, Amman, Jordan, eligible patients were interviewed from March 2010 to June 2011 using the Oxford Knee Score (OKS). In this cross sectional study, out of 550 patients undergoing TKA, 74 completed OKS health-status questionnaire preoperatively, at three and six months postoperatively, to determine the standardized response.
Results: Out of 74 patients, 18(24.3%) were male and 56(75.7%) were female. Smokers 10(13.5%) were smokers and 64(86.5%) non-smokers. 53 (71.6%) were married, 3 (4.1%) were single, 16 (21.6%) were widowed, and 2(2.7%) were divorced. In 10% the pain was severe. Almost one fifth had no pain after walking for more than 30 minutes. Only 8.1% experienced limping postoperatively. 26% of patients answering the questionnaire had satisfactory joint function, indicating that they may not require any formal treatment. Another 39% had mild to moderate outcome and needed only minimal treatment.
Conclusion: The study showed that daily life activities of patient's with TKA were not severely affected and postoperative pain was minimal. Many experienced satisfactory joint function.
