Evaluation of the patella following cartilage repair on conventional magnetic resonance imaging and T2 mapping

Abstract

This pictorial review aims to illustrate the role of conventional magnetic resonance imaging (MRI) and T2 mapping in the evaluation of the patella following cartilage repair. Through a series of representative images, this review demonstrates typical imaging findings from both modalities, emphasising their respective strengths in assessing graft morphology, early signs of viable and nonviable grafts, as well as diagnostic pitfalls. Conventional MRI is useful for visualising macroscopic changes. However, T2 mapping provides additional insight into the viability and integration of the cartilage, which may not be visible on conventional MRI. Together, these imaging techniques offer a comprehensive, noninvasive method for monitoring the success of cartilage repair, detecting complications, and guiding long-term patient management.
