To evaluate the effects of a knee flexion Dynasplint orthosis on knee flexion angle after a total knee arthroplasty. Sixty participants, who underwent a total knee arthroplasty, were randomly assigned in two groups: control group and Dynasplint group.
Post-surgical rehabilitation interventions following total knee arthroplasty consist mainly of stretching exercises to improve flexibility and prevent soft tissue fibroses around the joint, thus, avoiding contractures and providing increases in the range of motion at the knee joint. Although knee manipulation and open arthrolysis may improve range of motion after total knee arthroplasty , the results have been variable and additional procedures are frequently necessary. Studies demonstrated the effectiveness of dynamic orthoses in reducing joint contractures after orthopedic surgeries in various joints that require a long rehabilitation period. Therefore, the purpose of the present study was to evaluate the effects of the knee flexion Dynasplint orthosis (KFD) on the length of rehabilitation and range of knee flexion angle after total knee arthroplasty.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Dynasplint group | Experimental | The experimental group received standardized physical therapy intervention and used the knee flexion Dynasplint orthosis six hours daily during one month, starting at day seven after total knee arthroplasty surgery. |
|
| Control group | No Intervention | Control group received standardized physical therapy intervention. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Knee flexion Dynasplint orthosis | Device | Standardized rehabilitation procedures started at the first day after total knee arthroplasty. Both groups received the same standardized physical therapy intervention. The experimental group used the knee flexion Dynasplint orthosis (Dynasplint Systems, Inc. Canada, Woodbridge, ON) at night, while sleeping, over six continuous hours for one month, starting seven days after the total knee arthroplasty. The control group received only the standardized physical therapy intervention. |
| Measure | Description | Time Frame |
|---|---|---|
| The knee flexion angle was assessed in supine position with a universal goniometer | The outcomes were obtained by one experienced and well-trained physical therapist. | Change from baseline knee flexion angle at 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Measures of knee function. | Assessed by the Knee Society Score (KSS) | Change from baseline knee flexion angle at 6 months |
| Measures for quality of life | Assessed by Short-form 36 Health Survey (SF-36) |
