Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Knee injury and osteoarthritis outcome score (KOOS)
Tidsramme: Pre-operative, 1, 2 and 5 years
|
KOOS is a knee-specific questionnaire developed to evaluate short- and long-term symptoms and functioning in subjects with knee injury and osteoarthritis.
KOOS is validated for use in total knee arthroplasty and has been shown to be a valid, reliable and responsive measure.
KOOS is a patient-administered questionnaire.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Oxford knee score (OKS)
Tidsramme: Pre-operative, 1, 2 and 5 years
|
OKS is a brief patient-completed questionnaire for patients undergoing total knee arthroplasty.
It reflects the patient's assessment of their knee-related health status and benefits of treatment.
|
Pre-operative, 1, 2 and 5 years
|
|
EQ-5D-5L
Tidsramme: Pre-operative, 1, 2 and 5 years
|
EQ-5D-5L is a widely-used patient-administered instrument for describing health-related quality of life
|
Pre-operative, 1, 2 and 5 years
|
|
Range of motion (ROM)
Tidsramme: Pre-operative, 6 weeks, 3, 12, 24 and 60 months
|
ROM will be measured by extension and flexion with a goniometer preoperatively at baseline and at each follow-up visit (6 weeks, 3 months, 12 months, 24 months and 60 months
|
Pre-operative, 6 weeks, 3, 12, 24 and 60 months
|
|
Kinematic radiostereometric analysis (RSA)
Tidsramme: After 12 months
|
Knee motion while walking up and down stairs, and during squatting and kneeling activities will be recorded using video fluoroscopy (dynamic RSA) at 12 months.
|
After 12 months
|
|
Plain anterior posterior radiographs and hip, knee and ankle (HKA) radiographs
Tidsramme: Pre-operative, 3, 12, 24 and 60 months
|
Radiographs obtained for assessment of fixation of the prosthesis and the alignment.
|
Pre-operative, 3, 12, 24 and 60 months
|
|
Brief Pain Inventory
Tidsramme: Pre-operative, 6 weeks, 3, 12, 24 and 60 months
|
We will use three single items to measure worst pain intensity, average pain intensity, and pain interference with walking.
Patients rate their pain intensity and pain interference with walking on an 11-point numeric rating scale from 0-10, where 0=no pain/no interference and 10=worst imaginable pain/complete interference.

Pre-operative, 6 weeks, 3, 12, 24 and 60 months
