Complication Rate and Patient Satisfaction Following Bilateral Simultaneous Total Knee Arthroplasty

Abstract

Abstract Background Advanced knee osteoarthritis (OA) is a common clinical problem requiring knee arthroplasty. Knee Osteoarthritis can be diagnosed by X-ray. Total knee arthroplasty can be done simultaneous or staged in 2 different sessions. Aim of the Work To assess the results of simultaneously bilateral total knee arthroplasty as regard complications and patient satisfaction and compare to results in the literature to provide a clear guideline for proper choice of patients. Patients and Methods In the period between August 2018 and October 2020, a prospective cohort study was conducted in Ain Shams University Hospital in Cairo and Taiba hospital in Kuwait on 45 cases who suffered from advanced bilateral knee osteoarthritis and underwent bilateral simultaneous total knee arthroplasty. Results The study was conducted on a wide age group ranging from 47 to 75 years, (mean age 64.29±6.23 years). There was female predominance with 41 females with percentage 91.1% and 4 males with percentage 8.9%. Regarding patient satisfaction, the comparison of Pre- and Post-operative was 15.24±2.45, compared to 32.18±4.08 respectively, the mean difference 16.93. In comparing objective knee score by the Knee Society Scoring system, in each of Pre- and Post- operative was 58.90±6.28, compared to 82.62±5.70 respectively. Also, in Functional knee score in each of Pre- and Post-operative was 51.39±8.67, compared to 73.80±7.75 respectively. 4 patients (8.9%) had complications out of them 3 patients (6.7%) had superficial infection and 1 patient (2.2%) had acute coronary syndrome. Conclusion With careful preoperative patient selection bilateral Simultaneous total knee arthroplasty can be safe with low mortality and complication rates.
