Brief Summary
The goal of this clinical trial is to evaluate the effect, cost-effectiveness, safety and satisfaction with replacing standardized, pre-scheduled face-to-face visits with remote monitoring and video consultations or face-to-face consultations only when needed after total knee replacement surgery due to knee osteoarthritis. The primary outcome is the probability of being a OMERACT-OARSI responder at 6 months post-surgery. This is a composite index where participants are classified as a responder or non-responder based on improvement in pain, function and/or disease activity. Health-related quality of life and healthcare costs will be used to determine cost-effectiveness. Patient-reported adverse events and statisfaction will be used to determine safety and satisfaction. Patients will be recruited from Diakonhjemmet Hospital. Patients undergoing total knee replacement surgery will be randomly allocated to a control group who are summoned for a face-to-face consultation at Diakonhjemmet Hospital at 2 and 12 months, or a remote monitoring group who will not be scheduled for hospital visits but will answer patient-reported outcomes throught a web-application at 1, 2, 3, 6 and 12 months post-surgery and only be scheduled for hospital visits when needed. An additional study with follow-up after 5 and 10 years will be conducted.

Outcome Measures
Primary Outcomes (1)
OMERACT-OARSI responder criteria
The OMERACT-OARSI responder criteria is a composite index where participants are classifies as responders or non-responders (binary outcome) based on the following criteria: High improvement on pain or function * ≥50% improvement + absolute change of ≥2 points in pain, OR * ≥50% improvement + absolute change of ≥2 point on KOOS) OR Improvement in at least two of the three following * ≥20% improvement + absolute change of ≥1 point in pain * ≥20% improvement + absolute change of ≥1 point in function * ≥20% improvement + absolute change of ≥1 point in disease activity

Control group
ACTIVE COMPARATORPatients randomly allocated to standard follow-up will be summoned for a hospital visit with a physiotherapist at 8 weeks and 12 months post-surgery. The physiotherapist will conduct an assessment in line with regular clinical practice. If the patient is experiencing lack of improvement or adverse events, an orthopedic surgeon may be consulted. The patients will also answer patient-reported outcomes at 8 weeks and 6- and 12 months post-surgery, however, these answers will not be monitored.
Remote monitoring
EXPERIMENTALPatients randomly allocated to the remote monitoring group will answer patient-reported outcome at 1, 2, 3, 6 and 12 months. They will be provided with a brief introduction from the study personnel on how to answer questions remotely through the Youwell platform. Patients will get an SMS notification on their mobile phone with a link to the questionnaire. They will have to log in with BankID to access the questionnaire. A physiotherapist will monitor the answers and will contact the patient if an unexpected deterioration or adverse events are detected.
Interventions
The remote monitoring group will be more closely followed than the control group in order to detect any deterioration over time. This group will not be scheduled for a face-to-face consultation unless it is deemed necessary by a physiotherapist or if the patient contacts the hospital themselves.
The control group will follow usual care with face-to-face consultation with a physiotherapist at 2 and 12 months. They will also anwer questionnaires at 2, 6 and 12 months, but these will not be monitored.
Eligibility Criteria
