Quality-of-life assessment among patients undergoing total knee arthroplasty in Manaus

Abstract

Objectivethis study had the aim of assessing the quality of life among patients undergoing total knee arthroplasty (TKA). For this, the SF-36 and WOMAC questionnaires respectively were used to make comparisons with preoperative values.Methodsa prospective observational cohort study was conducted, with blinded analysis on the results from 107 TKAs in 99 patients, between June 2010 and October 2011. The present study included 55 knees/patients, among whom 73% were female and 27% were male. The patients’ mean age was 68 years. The SF-36 and WOMAC questionnaires (which have been validated for the Portuguese language) were applied immediately before and six months after the surgical procedure.Resultsthe statistical and graphical analyses indicated that the variables presented normal distribution. From the data, it was seen that all the indices underwent positive changes after the surgery.Conclusionsdespite the initial morbidity, TKA is a very successful form of treatment for severe osteoarthritis of the knee (i.e. more than two joint compartments affected and/or Ahlback classification greater than 3), from a functional point of view, with improvement of the patients’ quality of life, as confirmed in the present study. This study presented evidence level IV (description of case series), with analysis on the results, without a comparative study.

Forgotten Joint Score – Portuguese translation and cultural adaptation of the instrument of evaluation for hip and knee arthroplasties

“…The questionnaires frequently used to measure quality of life after arthroplasty that have been translated into Brazilian Portuguese are generic osteoarthritis assessment instruments, such as the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). 9 The Knee Injury and Osteoarthritis Outcome Score (KOOS), 10 Hip Outcome Score (HOS), 11 and Knee Society Score (KSS) 12 are more specific for the knee and hip joints. However, they were not specifically designed for arthroplasties.…”
