Comparative study of simultaneous and staged bilateral total knee arthroplasty: is age a key factor in surgical outcomes?

Compared with stgBTKA, simBTKA demonstrated superior efficacy in terms of reduced hospitalization duration and ORT, irrespective of age. Both surgical approaches yielded comparable clinical outcomes and complication rates across all age groups. Overall, the findings suggest that simBTKA is a viable option for appropriately selected patients, offering outcomes comparable to those of stgBTKA, with the added benefit of reduced hospitalization time and operating room utilization.
