Comparison of Arthroscopic and Magnetic Resonance Imaging Findings in Osteochondral Lesions of the Talus

Abstract

The MRI grading of osteochondral lesions in the talus was useful and showed a fairly good correlation with arthroscopic classification.

Diagnostic Value of CT Arthrography for Evaluation of Osteochondral Lesions at the Ankle

“…MRI is routinely used to detect chondral and osteochondral defects [25]. Despite some limitations, fairly good correlations of MRI grading of osteochondral lesions at the talus with arthroscopic findings were reported [26, 27]. However, both studies only assessed high-grade osteochondral lesions and only relate to the differentiation between loose and nonloose fragments.…”

Diagnostic imaging modalities for osteochondral defects of the talus

“…Another study by Lee et al showed similar results, namely 81% (42 of the 52 ankles) accuracy in staging OCD of the talus. In contrast, Bae et al used the grading system by Anderson [1] and reported a relatively low correlation rate of 65.9% [2]. A stronger magnetic field (e.g., 3.0 Tesla instead of 1.0 Tesla) may improve the visualization of the subchondral defect and cartilage [24].…”

Diagnosis and treatment of osteochondral lesions of the ankle: current concepts

“…Despite the known possibility of overestimation of injuries, there is a clear and well-defined trend in the literature to value images of osteochondral lesions of the talus obtained by MRI, 10 especially those of high-resolution, 11 due to their excellent correlation with arthroscopic findings, a fact which greatly helps in therapy planning and prognosis.…”
