Design outcomes

Primary

Measure	Time frame	Description
Knee Injury and Osteoarthritis Outcome Score (KOOS)	PRE surgery (assessed 1-14 days prior to surgery) and at 12 weeks and 52 weeks follow-up	Knee specific questionnaire. All domains on the KOOS. Primary end point is change from PRE surgery (assessed 1-14 days prior to surgery) to 52 weeks follow-up.

Secondary

Measure	Time frame	Description
Medical Outcomes Study 36-Item Short Form Health Survey (SF-36)	PRE surgery (assessed 1-14 days prior to surgery) and at 12 weeks and 52 weeks follow-up.	Generic health survey questionnaire.
Patient Acceptable Symptom State (PASS)	At 12 weeks and 52 weeks follow-up.	Dichotomous outcome (y/n) to the question: Considering your knee function, do you feel that your current state is satisfactory? With knee function you should take into account all activities you have during your daily life, sport and recreational activities, your level of pain and other symptoms, and also your knee related quality of life.
Treatment failure (TF)	At 12 weeks and 52 weeks follow-up.	Patients replying no to the PASS question will also be asked to answer (y/n) the following question: Would you consider your current state as being so unsatisfactory that you think the treatment has failed?. Patients replying, yes to the second question will be defined as experiencing treatment failure (TF).

Other

Measure	Time frame	Description
Global perceived effect (GPE)	At 12 weeks and 52 weeks follow-up.	Questions regarding global perceived effect (GPE) to explore minimal clinical important change in patient-reported outcomes.
