- Observational Cohort (Type: ACTIVE_COMPARATOR): If the patient can be included, but doesn't want to participate in the randomization, the patient is offered to enter into a prospective observational cohort with the same endpoints and the same follow-up as in the randomized study. The participant can then, in consultation with his/her physician, choose whether they would like MEDIC-treatment or TKR in combination with MEDIC-treatment.

Based on this trial design, predict the completion outcome and termination type (if applicable).
