RESUMO
Objective To compare the early efficacy of two different ways of rehabilitation exercises in total knee arthroplasty (TKA) patients. Method From January 2011 to January 2014,136 patients having undergone TKA were randomly divided into two groups. In group A , patients exercised under the guidance with doctor. In group B, patients exercised by using continuous passive movement (CPM) machine. Compared the data from the two groups including range of motion (ROM) of the knee joint, knee function score (KFS) and circumference of the knee joint, t test of independent sample was utilized in the research. Results All patientswere followed up in 4 weeks. The ROM and KFS of Group A was significantly better than Group B (P 0.05).Conclusion Group A and B are effective methods in TKA patients in early rehabilitation training. But training under the guidance of doctor has greater advantages than CPM.
