Introduction: The decision to perform Bilateral Total Knee Arthroplasty (BTKA) simultaneously or staggeredly is a significant topic of discussion in orthopaedics. Patients usually have a bilateral knee involvement in end stage arthritis and many factors contribute to the decision of staggered or simultaneous TKA. In this study we try and compare the functional outcome and complications related to both the methods.

Methodology: This was a retrospective study where we used the hospital records to find out the patients who have undergone bilateral simultaneous or staggard TKA in the past 2 years. We invited the patients to the hospital and patients were divided in to 2 groups of 100 each based on the surgery they had undergone. In follow up patients were evaluated on the basis of Knee Society Score (KSS) and complications that occurred post-surgery.

Results: The study included a total of 200 patients of which 160 were females and 40 were males. The average age of the patients was 64.5. on assessment of KSS score patients who underwent staggered TKA had a slightly better score as compared to the simultaneous group, the same was true even in the category of complications.
