Health related quality of life in patients having total knee replacement and associations with symptoms, recovery, and patient education : A six month follow up study

Abstract

Aim To describe the symptoms, recovery, patient education, and health related quality of life (HRQOL) of patients having total knee replacements at three time points and to detect experiences and situations that predict HRQOL six weeks and six months post-surgery. Method A prospective exploratory two-site study assessing 123 patients, while in hospital (T1), at six weeks (T2), and at six months (T3) post-discharge. HRQOL was measured using the SF-36v2 and symptoms were measured with the Hospital and Anxiety Scale. Two questions considered pain and two considered movement and tiredness while two questions addressed recovery and patient education. Linear regression models were used to calculate predictors of mental and physical HRQOL at T2 and T3. Results HRQOL improved from T1 to T3. The main predictors of higher physical scores at T2 were; being older, fewer symptoms of depression and little distress related to movement. At T3 the main predictors were; having resumed work, finding patient education very useful, experiencing no pain in the last 24 h and fewer symptoms of depression. The main predictors of higher mental scores at T2 were fewer symptoms of anxiety and depression and little distress related to movement while at T3 these were fewer symptoms of anxiety and depression and experiencing no pain last 24 h. Conclusion Apart from pain, function and resumption of activities, the symptoms of anxiety and depression influence HRQOL. These symptoms should be assessed during the hospital stay.
