• Finite element analysis optimizes unicompartmental knee prosthesis design by analyzing stress distributions in different prosthetic structures.
• It enables precise surgical planning by quantifying the biomechanical effects of osteotomy parameters such as tibial slope and joint line position.
• FEA predicts postoperative knee biomechanics, including ligament tension and cartilage contact pressure, non-invasively.
• It addresses limitations of 2D imaging by providing detailed 3D mechanical insights for unicompartmental knee arthroplasty.
