“…Our finds are consistent with those in studies demonstrating large treatment effects in terms of QoL after THA or TKA [ 4 – 7 , 21 ]. Nonetheless there is controversy whether THA or TKA provides greater or similar improvement.…”

BackgroundTo investigate and compare the impact of primary hip (THA) and knee (TKA) arthroplasty on quality of life in patients with osteoarthritis, to determine patients’ satisfaction with total joint arthroplasty, and to detect the effect of patients’ demographic and clinical characteristics on outcome.MethodsThree hundred seventy eight (378) patients with hip (174) and knee (204) osteoarthritis undergoing total joint arthroplasty (174 THA-204 TKA) were assessed pre- and post-operatively (6 weeks, 3, 6, and 12 months) using the Western Ontario and McMaster Osteoarthritis Index (WOMAC) and Centre for Epidemiological Studies Depression Scale (CES-D10). The patients’ satisfaction with the results of total joint arthroplasty was also assessed. Differences were analyzed using general linear model for repeated measures.ResultsThe one-year response rate was 97 % for THA and 90 % for TKA. WOMAC and CES-D10 scores improved significantly after one year for both THA and TKA (P < 0.0001). The improvement in WOMAC total score was significantly greater for TKA patients (P < 0.0001 at 12 months). WOMAC pain and stiffness improved earlier for THA (6 weeks), while TKA had equivalent improvements at 3 and 6 months respectively. Both THA/TKA displayed significant improvement of WOMAC function at 3 months but TKA had greater improvement. Age, body mass index, residence, education and social support were not significant predictors of quality of life after total joint arthroplasty. One year postoperatively 88 % of patients were satisfied.ConclusionsWOMAC and CES-D10 improved significantly one year postoperatively. Although pain and stiffness improved earlier in THA, functional improvement was inferior in THA compared to TKA.

Introduction: Total knee arthroplasty (TKA) is an effective treatment for knee osteoarthritis. Patient-reported outcome after TKA is influenced by multiple patient-related factors. The aim of this study was to prospectively evaluate preoperative patientrelated factors and to compare the self-reported outcomes 1 year after TKA among groups differing by age, sex, body mass index (BMI), education, and social support level. Methods: 314 patients, who underwent TKA in Vilnius Republican University Hospital between the end of 2012 and the middle of 2014, were included in a study. The preoperative and 12-month follow-up measurements were obtained using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Short . Differences between patient groups according to gender, age, BMI, level of education, and level of social support were analyzed. Results: At 12-month follow-up men demonstrated better results than women in WOMAC (P ¼ .003) and SF-12 both domains (P < .05). Patients with a higher social support demonstrated higher scores in physical function according to SF-12 (P ¼ .008). Better preoperative WOMAC and SF-12 scores were a predictor of better outcome 1 year after surgery. There was no difference in postoperative scores in different age, BMI, and education groups according to WOMAC and SF-12. Conclusion: There is no difference in self-reported functional outcome between patient groups differing in age, BMI, and education. Men and socially supported patients demonstrate better postoperative functional results 12 months after TKA. Better preoperative knee function and overall physical and mental function are predictors of better outcome 1 year after TKA. Age and obesity should not be limiting factors when considering who should receive this surgery.

“…Total Knee Arthroplasty (TKA) has transformed the treatment of end-stage osteoarthritis of the knee. 1,2 It is a highly successful, effective procedure that provides pain relief and restores function. 3 The National Joint Registry (NJR) for England, Wales and Northern Ireland reports that approximately 90 000 TKAs are performed annually.…”
