Knee Replacement, Total

Previous research has shown that use of rehabilitation (including physical therapy) and the recovery of function after knee replacement surgery may differ depending on patients' race, sex, income or insurance, and geographic location. In this study, the investigators will develop and test a new care pathway for knee replacement rehabilitation that is designed to maximize functional recovery for all patients and reduce differences between different groups of patients. Findings from this project will lead to improved rehabilitation quality after knee replacement surgery.

Some patients complain of articular noise (such as clicking, snapping, cracking or popping) after a total knee replacement. Controversy remains about whether there is a correlation between articular noise and worse outcomes following a knee replacement. A study by Nam et al. on 1540 patients revealed an association between noise and residual symptoms 30 days after they received a total knee replacement. Conversely, a study by Kuriyama et al. on 60 patients revealed no correlation between noise and patient satisfaction after 1 year of receiving a total knee replacement. The incidence of noise following a knee replacement has rarely been studied as a primary outcome. Like pain, it could be considered an important patient-reported outcome to assess patient satisfaction. The study aims to compare the prevalence of patient-perceived noise of an ultra-congruent total knee prosthesis (Score 2, Amplitude) versus a posterior-stabilized total knee prosthesis (Anatomic, Amplitude).
