Functional outcome of simultaneous bilateral total knee replacement (SBTKR): Prospective clinical study

Abstract

The functional outcomes and patient satisfaction scores are comparable, or higher, in persons undergoing bilateral TKA, and this occurs without a subsequent increase in out-of-pocket or insurance-covered medical expenses. Opponents of simultaneous bilateral TKA contend the procedure carries a higher mortality rate than staged bilateral TKA. Other opponents of simultaneous bilateral TKA cite an increase in postoperative complications and higher rehabilitation costs. Detailed history of all patients was taken. All patients were assessed clinically and functionally using the Knee Society Score and oxford knee score. The preoperative medical evaluation of all patients were done to prevent potential complications that can be life-threatening or limb-threatening. One way ANOVA was performed to assess the improvement in KSS score in left knee it was observed that the increase in score was statistically significant with F value of 65.6 and p<0.05. Further post Hoc analysis was done to assess the level of significance by multiple comparison it was observed that KSS score of left knee was significantly more at 3 months, 6 months, 12 months compared to preop levels p<0.05. The KSS score of left knee was significantly more at 6 months, 12 months compared to 3 months p<0.05 and The KSS score of left knee was significantly more at 12 months compared to 6 months p<0.05.
