Introduction: Total knee arthroplasty (TKA) is a valid therapeutic option for patients with severe arthritis and physical disability. However, many TKA patients develop pain and functional impairment. In our study, we used a continuous passive motion (CPM) device for exercise starting 10 days after surgery. Materials and Methods: The study population consisted of 60 patients, who were randomized into 2 groups. Group I (GI: 30 patients, 23 females) underwent the standard treatment and group II (GII, 30 patients, 17 females) underwent the standard treatment plus CPM starting 10 days after surgery. We evaluated pain, range of motion (ROM), extension muscle strength, and function (WOMAC and TUG tests). Results: All compared parameters yielded no statistically significant differences. A greater trend toward improvement was observed in GII regarding some parameters: greater extension muscle strength and a baseline correlation between flexion strength and the TUG test. Conclusions: The use of CPM starting 10 days after of surgery improved the extension muscle strength and produced better TUG test results, although without any statistically significant difference with the standard procedure. No adverse effects were observed.
