Change in Quality of life assessment (EQ5D-5L) |
assessment of 5 dimensions of life: mobility, self-care, activities of daily living, pain and psychological well-being in each 5 categories ranging from "no problems" to "extreme problems" |
assessed on day 0 preoperative, day 8 and week 12 after start of intervention |
|
Other |
Change in patient satisfaction with the received treatment (VAS) |
visual analogous scale (VAS) on which the patient can rate satisfaction with the received treatment; Scale from 0 = not at all satisfied to10 = very satisfied |
assessed on day 8 and week 12 after start of intervention |
|
Other |
Change in Knee disability and Osteoarthritis Outcome Score (KOOS) |
Patient reported score. The KOOS results in summary scores for five subscales. It holds 42 items in 5 separately scored subscales; Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec) and knee-related Quality of Life (QOL). A Likert scale is used and all items have five possible answer options scored from 0 (No Problems) to 4 (Extreme Problems) and each of the five scores is calculated as the sum of the items included. Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee Problems. |
assessed on day 8 and week 12 after start of intervention |
|
Primary |
Change in leg circumference between day 1 and day 8 (in cm) |
Leg circumference will be measured at three levels (joint space, 5cm proximal, 5cm distal) with each three measurements performed by one assessor in all patients and time points. The primary endpoint will be the mean of the three measurements |
day 1 postoperatively before start of intervention and every day thereafter for 7 days |
|
Secondary |
Change in leg circumference between day 0 and day 8 (in cm) |
Leg circumference will be measured at three levels (joint space, 5cm proximal, 5cm distal) with each three measurements performed by one assessor in all patients and time points. The primary endpoint will be the mean of the three measurements |
day 0 preoperative and day 1 postoperatively before start of intervention and every day thereafter for 7 days |
|
Secondary |
Change in leg circumference between day 0 and after 6 weeks and 12 weeks (in cm) |
Leg circumference will be measured at three levels (joint space, 5cm proximal, 5cm distal) with each three measurements performed by one assessor in all patients and time points. The primary endpoint will be the mean of the three measurements |
day 0 preoperative and after 6 weeks and 12 weeks after start of intervention |
|
Secondary |
Change in range of motion of knee (in degree) |
range of motion measured using the neutral zero method |
day 1 postoperatively before start of intervention and at day 8 after start of intervention and after 6 and 12 weeks after start of intervention |
