Presentation: Joint Balance Throughout Flexion Has Greater Impact on One Year Pain Outcome Than Component Alignment in TKA

Recently, some recent findings related to the field of total knee arthroplasty were presented at the 2020 ISTA NEWS Meeting on behalf of the Corin clinical team. Titled Joint Balance Throughout Flexion Has Greater Impact on One Year Pain Outcome Than Component Alignment in TKA, this presentation received the award for best presentation in the subject of Cost and Clinical Effectiveness of Innovations in Arthroplasty.

OMNIBotics uses robotic instrumentation and advanced software to plan and execute TKA procedures with proper ligament balance throughout range of motion. By capturing intra-operative joint balance and resection data, OMNIBotics allows surgeons to predictively plan post-operative joint balance by virtually adjusting the femoral component placement. The availability of such data raised the question: What is the optimal soft-tissue balance in TKA, and does component alignment matter?

By combining procedural data with patient outcomes, our work shows that soft tissue balance and laxity targets exist throughout flexion, and that when all targets are satisfied, a clinically important difference in post-operative pain is achieved. Small deviations in component alignment, however, were not associated with outcome, indicating that balance has a greater impact on outcome than alignment.
