Uitkomstmaten
Primaire uitkomstmaten
To demonstrate that x-ray based-PSI can be used as template modality to predict the actual size of both the tibial and femoral component sizes as used intraoperatively with MRI-based PSMI, with the aim to reduce costs.
Achtergrond van het onderzoek
Results in literature on the topic of size prediction vary with authors reporting good accuracy of the PSI to predict component size and others reporting frequent intraoperative directed changes. This industry driven intervention aims to reduce hospital costs. Although, results on this topic are inconclusive. Recently, 2D PSMI models are developed. These models can save money since a MRI is not necessary. With the use of x-rays of the knee joint, 2D PSMI guides can be manufactured.
