Study Overview
Brief 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.

Outcomes
Primary Outcomes
Oxford Knee Score
Time Frame: 12-months post-operative
The Oxford Knee Score (OKS, best to worst 0-48) measures pain intensity and functional limitation of the knee during various activities. The questionnaire consists of 12 items. The maximum total score is 60 and corresponds with the highest pain intensity and functional limitation.
Oxford Knee Score
Time Frame: 3-months post-operative
The Oxford Knee Score (OKS, best to worst 0-48) measures pain intensity and functional limitation of the knee during various activities. The questionnaire consists of 12 items. The maximum total score is 60 and corresponds with the highest pain intensity and functional limitation.
