Effect of Changes in Posterior Tibial Slope Angle Under Continuous Dynamic Loading During the Gait Cycle on the Wear of Knee Implant Polyethylene Insert

Abstract

Knees are the joints that allow us to do our daily tasks such as walking, running, sitting, standing and carrying the weight of our body. Knee pain occurs due to wear and tear in the cartilage tissues of the knee joints. Various medical and physical treatments are applied to patients to relieve this pain. Total knee arthroplasty (TKA) treatment is applied to patients whose pain does not decrease despite these treatments. Arthroplasty is performed by cutting the damaged joint tissues and adding polyethylene and metal parts instead. Arthroplasty is an application made by adding metal components and polyethylene intermediate component material to the surface of the tibia, femur and patella bones in the damaged knee joint. Tibial inclination is an important factor in knee kinematics and arthroplasty surgeries. Tibial inclination is defined as the anatomical inclination of the tibial plateau towards the posterior in the sagittal plane. This inclination is the angle between the direction perpendicular to the axis of the tibia and the parallel direction of the tibial plateau. It has values that vary between 6° and 13°. This study aims to numerically calculate and obtain information on the Posterior Tibial inclination angle change, pressure distributions on the interface due to the loads acting on the PE insert due to flexion effects and wear information. It is observed that the Posterior Tibial inclination angle, which occupies an important place in the amount of load on the contact interface and the amount of wear on the insert after knee implant assembly, slightly decreases as the amount of wear increases with the number of cycles. This decrease is due to the vertical loading force applied to the PE insert-Femoral component interface at 0 degrees assembly and taken as 50 N in this study, being separated into two components as perpendicular and parallel to the contact interface as the assembly angle changes; the parallel force increases as the angle increases and the perpendicular force decreases.
