Evaluating Patient Satisfaction Outcome After Total Knee Arthroplasty Done at Our Hospital's Joint Replacement Registry, Egypt.

Abstract

Total knee arthroplasty (TKA) is a highly effective intervention for enhancing function and quality of life in cases with advanced knee osteoarthritis. Although multiple factors have been identified as influencing TKA outcomes, it remains challenging to accurately predict which patients will experience dissatisfaction postoperatively, thereby complicating efforts to optimize their management. This study aimed to evaluate the patient satisfaction outcome after TKA done at our hospital's joint replacement registry using the updated Knee Society Scoring System. This retrospective observational study was conducted on 900 cases who underwent a TKA. The same surgeon consultant, head of the department, performed all the surgeries. SF-12 scores and total new knee society scoring (satisfaction subscale, expectation subscale, function activity subscale, and total score) were markedly higher at the end of follow-up than at the baseline (P < 0.05). A negative correlation was found between new knee society scoring, and age and body mass index(P < 0.05). A positive correlation was found between new knee society scoring, and duration of follow and SF-12 as P < 0.05. New knee society scoring was markedly higher in men than women (P = 0.011). New knee society scoring was markedly different among causes of arthroplasty (P = 0.005). An overall satisfaction rate was there among the studied cases regarding SF-12 score, which measures the activity and mentality of the cases postoperatively; in addition, most of the studied group show a notable improvement in new knee society score.
