Robotic TKA Improves Radiological Outcomes, Short-Term Inflammation & Limb Positioning for Knee OA
Thirty patients with knee osteoarthritis (OA) and undergoing a primary total knee arthroplasty (TKA) were randomized to receive a conventional jig-based TKA (n=15) or robotic-arm assisted TKA (n=15). Outcomes of interest included changes in systemic inflammatory markers (i.e. interleukin-1β [IL-1β], interleukin-6 [IL-6], tumour necrotic factor α [TNF-α], white cell count, neutrophils, lymphocytes, platelets, lactate dehydrogenase [LDH], alkaline phosphatase [ALP], cortisol levels, hemoglobin [Hb] levels, erythrocyte sedimentation rate [ESR], creatine kinase[CK], and C-reactive protein [CRP]), planned positioning of components, periarticular soft tissue injury and bone trauma using the the Macroscopic Soft Tissue Injury (MASTI) classification system, mean length of incision, mean surgical time, mean change in Hb levels, and mean knee temperature. All inflammatory markers were evaluated at 1 day, 2 days, 7 days, and 28 days post-surgery. Mean knee temperature was also measured at 6-days
