“…MR arthrography has low spatial resolution, and it is unable to separate the closely apposed tibial and talar cartilages and could not detect partial thickness chondral defect. On the other hand, the inherent high resolution of CTA permits easy depiction of the articular cartilage along each articular surface across the joint, and the articular cartilage is clearly seen by virtue of five thin alternating layers of high and low attenuations formed by hyperdense subchondral bone plate, hypodense hyaline cartilage on each side of the joint, and intervening hyperdense contrast material [14][15][16][17].…”

Background: Post-sprained ankles may sustain ligamentous tear, chondral defect, or osteochondral lesions (OCL). Being widely available and does not depend on high-end machine, the aim of this study was to assess the value of high resolution multi-detector CT arthrography (CTA) in detection of various ligamentous tears, chondral defects, and osteochondral lesions in case of sprain-related persistent ankle pain. Results: There were 34 (68%) cases of ligamentous injury, most of which had single ligament affection whereas some cases demonstrated multi-ligamentous injury, and the total number of individual injured ligaments was 42 ligaments. There were 36 cases (72%) which had either chondral or osteochondral defects; the total number of OCL was 21 lesions and the total number of segmental cartilage defects was 20. Conclusion: This study emphasized the diagnostic importance of multi-detector CTA in sprain-related ankle pain. In persistent post-sprained ankle pain, multi-detector CTA is a helpful imaging modality which could be utilized for detection of OCL, chondral defects, and various ligamentous tears.
