Total Knee Arthroplasty

rehabilitation, total knee arthroplasty
Brief summary
The purpose of this study is to compare the effectiveness of inpatient and outpatient rehabilitation following total knee arthroplasty. No studies exist that have evaluated these two rehabilitation programmes in a specific orthopaedic patient population with a focus on motor performance. We hypothesized that patients participating in outpatient care tend to be physically more active than patients in the rehabilitation clinic, leading to the assumption that outpatient rehabilitation has superior functional outcomes compared to the inpatient standard-of-care therapy.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| physical activity (number of steps) | during the first seven days of rehabilitation and 3 months post surgery (posttest) | over a period of 7 days using activPAL activity recording system |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| maximal active and passive knee joint range of motion | change from baseline (9 days after surgery) to posttest (3 months after surgery) | digital long-arm goniometer |
| stair climbing performance | change from baseline (9 days after surgery) to posttest (3 months after surgery) | stair climbing test |
| timed up and go performance | change from baseline (9 days after surgery) to posttest (3 months after surgery) | timed up and go test |
| gait performance | posttest (3 months after surgery) | spatio-temporal and temprophasic gait parameters |
| knee pain | change from baseline (9 days after surgery) to posttest (3 months after surgery) | visual analogue scale |
| knee joint swelling | change from baseline (9 days after surgery) to posttest (3 months after surgery) | measurement of circumference |
| long-term Memory representation of the gait | change from baseline (9 days after surgery) to posttest (3 months after surgery) | structural dimensional analysis of mental representation (SDA-M) |
| joint position sense | change from baseline (9 days after surgery) to posttest (3 months after surgery) | The subjects' ability to actively reproduce a previously presented knee flexion angle (30° and 50° of knee Flexion) |
