Article abstract


The Knee Self-Efficacy Scale (K-SES) has good reliability, validity, and responsiveness for patients' perceived knee-function self-efficacy during rehabilitation after an anterior cruciate ligament (ACL) injury. Preoperative knee-function self-efficacy has also been shown to have a predictive ability in terms of outcome 1 y after ACL reconstruction.


To evaluate a new clinical rehabilitation model containing strategies to enhance knee-function self-efficacy.


A randomized, controlled study.


Rehabilitation clinic and laboratory.


40 patients with ACL injuries.


All patients followed a standardized rehabilitation protocol. Patients in the experimental group were treated by 1 of 3 physiotherapists who had received specific training in a clinical rehabilitation model. These physiotherapists were also given their patients' self-efficacy scores after the initial and 4-, 6-, and 12-mo follow-ups, whereas the 5 physiotherapists treating the patients in the control group were not given their patients' self-efficacy scores.


The K-SES, the Tegner Activity Scale, the Physical Activity Scale, the Knee Injury and Osteoarthritis Outcome Score, and the Multidimensional Health Locus of Control.


Twenty-four patients (12 in each group) completed all follow-ups. Current knee-function self-efficacy, knee symptoms in sports, and knee quality of life improved significantly (P = .05) in both groups during rehabilitation. Both groups had a significantly (P = .05) lower physical activity level at 12 mo than preinjury. No significant differences were found between groups.


In this study there was no evidence that the clinical rehabilitation model with strategies to enhance self-efficacy resulted in a better outcome than the rehabilitation protocol used for the control group.
