How satisfied are our patients after total knee arthroplasty?

Abstract

Introduction: Subjective patient satisfaction and patient reported outcomes after arthroplasty is becoming an increasingly important parameter of success. In Hong Kong, information regarding patient satisfaction after arthroplasty is lacking and we have no local data. This study aimed to determine the degree of satisfaction after TKR in our local population. Methodology: 106 patients undergoing primary TKR in a public hospital were enrolled. Operating surgeons completed a standardised questionnaire regarding their prediction of the operated patient’s ultimate satisfaction. At 6 weeks, 3 months and 6 months post-operation, patients completed a standardised satisfaction questionnaire. Results and Analysis: 91% of patients were satisfied with their operation overall. The average satisfaction score of 8.6+/-1.7. 85% and 91% of patients were satisfied with the degree of pain relief and functional improvement after surgery respectively. Male gender and being on waiting list for <36 months was associated with higher satisfaction. Surgeon’s prediction of patient’s satisfaction with function was significantly positively correlated with patient reported satisfaction and post-operative New Knee Society Knee Satisfaction score. Discussion and Conclusion: Overall patient satisfaction levels were high amongst the study cohort. Pre-operative factors affecting satisfaction have been identified that can form the basis for future study directed at the generation of a predictive model for satisfaction after total knee replacement which is of relevance for our local population.
