Abstract
BACKGROUND:Total knee replacement is regarded an effective treatment of knee osteoarthritis, based on the transformation of biology-psychology-social medicine pattern, the concept of“quality of life”has attracted increasing concerns. <br> OBJECTIVE:To observe the effects of total knee replacement surgery on the pain, function and quality of life among elder patients with severe knee osteoarthritis. <br> METHODA total of 102 elder patients with severe knee osteoarthritis were recruited from the Second Affiliated Hospital of Inner Mongolia Medical University between January 2010 and January 2013. The clinical manifestations and 12-month fol ow-up outcomes were observed and recorded. The involved patients were randomly divided into two grouptreatment group (59 cases, receiving total knee replacement) and control group (43 cases, receiving expectant treatment such as drugs, but no surgery). Patients were evaluated using HSS scale and WHOQOL-100 scale before surgery and 12 months after surgery. Furthermore, the correlation between influencing factors and HSS and WHOQOL-100 scores was analyzed. <br> RESULTS AND CONCLUSION:At 12 months postoperatively, the HSS scores of patients in treatment group was (82.03±10.17) points, which was obviously higher than that in control group (P<0.01). The WHOQOL-100 scores in treatment group were also significantly higher than that in control group (P<0.01). The psychology sub-item scores of patients after total knee replacement were close to that of normal controls (P>0.50). The regression analysis shows that marital status (β=1.988), complication (β=2.035) and HSS scores (β=2.108) are the main influencing factors for the quality of life among patients undergoing replacement. Experimental findings indicate that, HSS score is an effective indicator to assess the effect of total knee replacement on the pain and function of elder patients with severe knee osteoarthritis. WHOQOL-100 is introduced to further improve the assessment of quality of life after total knee replacement surgery in severe knee osteoarthritis. The marital status, complication and HSS scores are the key influencing factors for the quality of life among severe knee osteoarthritis patients. Deep vein thrombosis affects the out-of-bed time, and the mate-accompanying during the fol ow-ups plays a positive role on the quality of life and mental state of patients.关键词
