Hip and/or knee osteoarthritis Wear and tear of hip and/or knee joints
Conditions
Interventions
Study population: Patients scheduled for THA or TKA who experience pain and disability in the knee or hip joint due to osteoarthritis, and aged = 50 years at the time of the surgery.Intervention: 
Check-up on demand (COD) by the patient or healthcare provider (HCP), after a final clinical visit  
within 3 months to diagnose complications and provide instructions when to contact an HCP.Comparator: Routine follow up (RFU) consisting of an 
X-ray and clinical visit within 3 months and at 1 year after surgery. Patients are welcome to contact an HCP in case of pain, concerns or other symptoms associated with their prosthesis at any time.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study parameters are clinical and process outcomes. The clinical outcome is patient-reported physical function, measured with the PROMIS questionnaire, 2 years after surgery (1 year after RFU or COD). The process outcome is healthcare consumption, including X-rays, clinical visits, and diagnostic tests. | — |
Secondary
| Measure | Time frame |
|---|---|
| Number and type of complications (e.g. infection, peri-prosthetic fracture, loosening, malalignment or malposition of components, prosthetic wear, dislocation, etc.)Number and type of surgical interventions (e.g. DAIR, partial component exchange, revision surgery (full prosthesis replacement), irrigation and debridement (without component retention), etc.)Additional healthcare consumption related to THA or TKA FU (e.g. clinical visit, telephone consultations, X-ray, CT scan, MRI scan, laboratory tests, other)Health related quality of life (EQ-5D-5L)Numeric Pain Rating Scale (NPRS)Numeric Satisfaction Rating Scale (NSRS)Costs (based on electronic patient records and additional questionnaires, including all visits to healthcare providers outside the hospital) | — |
