In a recently published study, researchers found patients with knee arthritis who underwent simultaneous bilateral total knee arthroplasty had better functional outcomes than those who underwent simultaneous unilateral total knee arthroplasty.
The researchers retrospectively reviewed 511 consecutive patients with bilateral knee arthritis who underwent either simultaneous bilateral or unilateral (186 and 325 knees, respectively) total knee arthroplasty (TKA) during a 5-year period. Functional outcomes — including range of motion, flexion and functional scores — and Knee Society Score values were the primary metrics evaluated.
Patients in the bilateral TKA cohort exhibited significantly better increases than the unilateral TKA group in flexion (6.71° and 3.8°, respectively) and function (88.88 and 84.39, respectively) values.
