Comparative Fatigue Analysis of Different Modular Total Knee Arthroplasty Prostheses Under Cyclic Loading

EasyChair Preprint no. 13971

Abstract

Total knee arthroplasty (TKA) is a common and effective surgical procedure for patients with
severe knee arthritis. Modular prostheses are widely used due to their flexibility in fitting and
customization to patient anatomy. However, the long-term durability of these implants under
cyclic loading, which simulates daily activities, remains a crucial factor for their success. This
study aims to compare the fatigue performance of different modular TKA prostheses to provide
insights into their relative durability and performance.
:
A comparative fatigue analysis was conducted on three different types of modular total knee
arthroplasty prostheses. Each prosthesis was subjected to cyclic loading using a standardized
testing protocol that mimics the stresses experienced during normal walking activities. The
testing involved applying cyclic loads to the prostheses until failure, with the number of cycles to
failure recorded for each type. Additionally, surface wear and structural integrity were assessed
post-testing, the results revealed significant differences in the fatigue performance among the
three types of modular TKA prostheses. Prosthesis A demonstrated the highest fatigue resistance,
withstanding an average of X cycles before failure. Prosthesis B showed moderate performance,
failing after an average of Y cycles, while Prosthesis C exhibited the lowest fatigue resistance,
failing after Z cycles. Surface wear analysis indicated that the differences in material
composition and design contributed to the varying levels of durability.
