Summary

This is a randomized clinical study, in which 150 patients with end-stage osteoarthritis will be enrolled to ROSA®-assisted knee arthroplasty or conventional knee arthroplasty. Patients are recruited at Zuyderland Medical Center, enrolled pre-operatively and followed up for 12 months post-surgery. In- and exclusion criteria are stated below.

After recruitment, participants will be invited for a pre-operative visit. During this pre-operative visit Informed Consent is signed and completion of patient-reported outcome measures (PROMs) is checked. Additionally, measurements regarding body composition, strength and fitness and metabolic outcomes are performed. Participants will have a blood sample taken. Scans, adverse event and medication use will be confirmed. Participants will receive a ActiGraph for collecting data from physical activity. Of all patients, 72 will undergo additional measurements (gait, proprioception).

During surgery ROSA- and surgery-data will be collected. Post-operative participants will have a 6-weeks, 3-month and 12-month visit. During these visits pre-operative measurements are repeated.

PROCEDURE

Robotic-assisted total knee arthroplasty (raTKA)

Robotic-assisted total knee arthroplasty is an orthopaedic surgery that involves replacing the articular surfaces (femoral condyles and tibial plateau) of the knee joint with smooth metal and highly cross-linked polyethylene plastic. The robot (ROSA Knee System, Zimmer Biomet, US) assists in planning and placement of the implants and resection sites.

PROCEDURE

conventional total knee arthroplasty

total knee arthroplasty is an orthopaedic surgery that involves replacing the articular surfaces (femoral condyles and tibial plateau) of the knee joint with smooth metal and highly cross-linked polyethylene plastic. In conventional TKAs, no patient-specific instrumentation or robotic assistance is provided.
