Retrospective analysis of Clinical Outcomes and Complications of One-stage versus Two-staged Bilateral Total Knee Arthroplasty.


Introduction: The safety of single staged bilateral TKA has been issue of debates due to concerns of morbidity and mortality. The advantages attributed to one-stage bilateral TKA include shorter recovery time, shorter hospital stay and perhapsreduced total cost of treatment. The aim of thisstudy was to analyze the clinical outcomes and complications following one-stage versus two-staged bilateral TKA for severe osteoarthritis of both knees.

Methods: This retrospective comparative analysis was carried out between January 2018 and December 2022 at a government orthopaedic referral hospital in Nigeria. Clinical outcomes using KSS scoring system and rate of complications were recorded. Patients’ satisfaction using Likert scale was also documented. The statistical analysis was performed using SPSS version 23.0.

Result: There was no significant difference between the postoperative KSS in the two groups (p = 0.717) The mean postoperative KSS in OS and TS groups were 97.78 ± 1.78 and 97.76 ± 1.74 respectively. Postoperative complications do not also significantly differ in the two groups (P=0.712)

Conclusion: In properly selected cases, one-stage bilateral TKA has the same good outcome and excellent patients’satisfaction as two-staged procedure without significant increase in complication rates.
