| Abstract [eng] |
A primary total knee arthroplasty (TKA) is an effective treatment for an end stage knee osteoarthritis. TKA is aimed to provide long lasting joint which relieves pain and improves patient’s physical function. However, a significant patient population (10-20%) is still experiencing unsatisfactory results. Patient-reported outcome measures (PROM’s) have become a corner-stone of outcome assessment after joint surgery. The prospective observational study was performed at the Republican Vilnius University Hospital, Vilnius, Lithuania, from October 2012 to April 2014. 314 patients enrolled in a study. The aim of this study was to prospectively evaluate the influence of preoperative patient factors on patient reported outcome one year after total knee arthroplasty. We had three objectives: 1.To compare WOMAC and SF-12 scores change among patient groups differing by age, sex, education level, social support level, BMI, place of residence, co-morbidities according to Charnley and stage of knee osteoarthritis according to Ahlback. 2.To find out preoperative patient factors which predict knee pain and function in one year following total knee arthroplasty. 3.To find out the proportion and which patients do not respond to total knee arthroplasty according to OMERACT-OARSI set of responder criteria. |
