Randomized Study Comparing Noise and Patient Perception After Two Types of Total Knee Replacement

What this Trial Is About

Researchers are evaluating the presence and perception of articular noise, such as clicking or popping sounds, in patients who have undergone total knee replacement surgery. The study aims to compare the prevalence of these noises between two types of knee prostheses an ultra-congruent total knee prosthesis Score 2, Amplitude and a posterior-stabilized total knee prosthesis Anatomic, Amplitude. This is important because previous studies have shown mixed results regarding the association between noise and patient discomfort or satisfaction after knee replacement. The study involves two groups receiving different types of total knee arthroplasty TKA. One group will receive the Score II ultra-congruent mobile-bearing cemented prosthesis designed to prevent femoral condyle subluxation during knee movement. The other group will receive the Anatomic posterior-stabilized fixed-bearing cemented prosthesis, which has a cam and post mechanism to provide knee stability. Only the cemented versions of both prostheses will be used in this randomized trial. Participants will be followed for up to two years, with assessments at one and two years after surgery. Researchers will measure the prevalence of articular noise, characterize the noise by discomfort, type, and location, and evaluate its impact on quality of life. Patient-reported outcome scores will also be collected. The study will monitor participant compliance and outcomes to better understand how these prosthesis designs affect noise perception and patient satisfaction over time.
