Abstract: Background: Bilateral total knee arthroplasty (TKA) is one of the most common surgeries performed in patients with Osteoarthritis knee. The functional assessment in between two knees have not been in literature which is an important evaluation to help provide patients with evidence based outcome. We evaluated the functional outcomes on operated Bilateral TKA patients and compared them between the two knees.
Methodology: Patients who underwent primary Bilateral sequential and staggered TKA between 1st January 2019 and 31st Dec 2019, were included and their functional outcomes were assessed at 6 weeks, 3 month, 6 months and 1 year intervals were evaluated in our study.
Results: With a mean age of 66.95 years (50-82), 142 primary bilateral total knee replacements were included. In the 142 patients observed a total of 17 patients had a difference in the left and right knees where 13 patients had right knee better than left and the other 4 had left better than right based on the KSS score. In conclusion, the differences between knees were not significant over 1 year period follow-up based on the KSS scores.
Conclusion: In our study, we found that functional outcomes of knees based on KSS scores were different in the early follow ups at 6 weeks and 3months interval but at a long term follow up of 1 year the differences were not significant.
