Aim: We aimed to conduct a study comparing early outcomes of bilateral total knee replacement (BTKR) done in single sitting versus double sitting. Materials and Methods: The study included 58 patients who were already operated case of BTKR done in single sitting (sequential BTKR) – Group I (n = 30) and double sitting (staged BTKR) – Group II (n = 27), during time period April 2016 to May 2019. At follow-up, functional outcome in both the groups was assessed by Knee Injury and Osteoarthritis (OA) Outcome Score, Western Ontario and McMaster Universities OA Index score, and Visual Analog Scale scores. Results: The mean age in Group I was 64.5 ± 10.52 years and in Group II was 63.92 ± 5.76 years. The mean body mass index (BMI) in Group I was 28.42 ± 1.365 kg/m2, whereas the mean BMI in Group II was 29.19 ± 1.898 kg/m2. The mean length of hospital stay in Group I was 15.23 ± 2.921 days as compared to 23.69 ± 5.259 days in Group II. There was no mortality in both the groups within 90 days after operation in both the groups. There was significantly less requirement of hospital stay in Group I as compared to Group II (P = 0.001, Mann–Whitney U-test). Conclusion: We found that the single sitting BTKR is cost-effective and a relatively safe surgery. There was significantly lower length of hospital stay in single sitting BTKR along with no major complication in our study. Thus we advocate BTKR as a single sitting surgery with proper patient selection and preanesthetic workup.
