Magnetic resonance imaging aspects after surgical repair of knee cartilage: pictorial essay

Abstract

<jats:p>Abstract Radiologists should be familiar with the main techniques of knee cartilage repair and the imaging methods available for its evaluation, in order to optimize the postoperative follow-up of patients. The objective of this study was to present a series of clinical cases seen at our facility, illustrating the main techniques necessary for the repair of knee cartilage, as well as the magnetic resonance imaging techniques used in the postoperative evaluation and the relevant radiological findings.</jats:p>

Patellar chondropathy: a brief overview of its history and prevalence

“…As a noninvasive method for diagnosing chondral lesions, MRI has produced varied and controversial results, those results being heavily dependent on the type of sequence used, field strength, degree of chondral injury and level of experience of the examiner. Another important point is that MRI can be used not only in the diagnosis and classification of chondral lesions but also in the evaluation of the repair process and postoperative evolution of such lesions ( 4 ) . It has been known for more than a decade that 3.0 T scanners perform better than do 1.5 T scanners, which in turn perform better than do those with even lower magnetic fields strength ( 5 ) .…”

Imaging assessment of surgical repair of knee cartilage

“…In the previous issue of Radiologia Brasileira, Souza et al (6) provided a complete didactic pictorial essay of surgical repair of knee cartilage evaluated with MRI.…”
