Background Knee osteoarthritis is a long- term disease and its medical management is not always effective in reducing pain or improving mobility. The studies concerning the quality of life in patients with knee osteoarthritis proved the impact of functional impairment on their daily living activities and on their social and professional life.
Objectives The main purpose of this observational study was to evaluate the efficacy of complex rehabilitation treatment and its influence on the functional status and on the quality of life in patients with knee osteoarthritis and to identify possible correlations between various clinical and functional parameters.
Methods The study included 138 patients with knee osteoarthritis (diagnosed according to the American College of Rheumatology criteria), mean age 64.52±11.63 years. All patients performed a complex rehabilitation program for 12 days and were evaluated clinical and functional at baseline, at 2 weeks and at 8 weeks. We used VAS scale for pain measure, WOMAC index for functional status and the Short Form 36 Helth Survey (SF-36) for assessing quality of life. The physical performance measures included the Six- Minute Walk Test (SMW) and the Timed “Up & Go” Test (TUG).
Results The efficacy of physical-kinetic treatment is reflected by statistically significant improvements (p<0.05) of mean scores for functional status and for quality of life questionnaires, for pain evaluated on a visual analogue scale (VAS). WOMAC influence on SF-36 improvement is well above 50%; there is a correlation between indicators estimated as moderately high (0.8). Multivariate analysis showed that physical performance measures (SMW and TUG) correlated statistically with pain measure (VAS score) and WOMAC index.
Conclusions Improvement of the clinical and functional parameters has a significant impact on increasing the quality of life in patients with knee osteoarthritis.
