Keywords: Total Knee Arthroplasty; UHMWPE; Tibial Spacer
ABSTRACT: A conventional UHMWPE tibial spacer and a spring-integrated spacer manufactured were evaluated under compressive loading using FEA in ANSYS Workbench at 3.085 MPa. The conventional design showed a maximum von Mises stress of 9.91 MPa and deformation of 0.312 mm, while the spring-integrated design exhibited 862.66 MPa stress and 0.899 mm deformation. Although the spring design provides greater compliance and shock absorption, its high stress concentration indicates the need for further optimization. Overall, the conventional spacer demonstrated better structural stability.
