Implementation of Indication Criteria for Total Knee Replacement in Osteoarthritis (Value-based TKR)

Not Applicable

Completed

• Conditions: Knee Osteoarthritis; Arthroplasty, Replacement, Knee
• Interventions: Other: Routine care; Other: Digital decision aid for physicians and patients

• Registration Number: NCT04837053
• Lead Sponsor: Technische Universität Dresden

Brief Summary

The aim of this trial is to investigate the effect of a medical decision aid (EKIT-Tool) on decision quality for knee arthroplasty.

Detailed Description

The tool will guide the SDM process and support the consultation, providing a systematic presentation of individual patient and disease-specific information and the fulfilment of indication criteria. Furthermore, it will present health information about knee replacement to empower the patient. To investigate the effect of the tool on decision quality, we choose a prospective multi-center, stepped wedge, cluster randomized controlled trial (SW-RCT) design.
