"Osteochondral autograft transplantation has been evaluated with MR imaging and includes the assessment of defect filling, the peripheral integration and morphologic characteristics of the bony and cartilaginous portions of the cylindrical, osteochondral plug as well as the evaluation of the donor site. MRI sequences most commonly used for the evaluation of cartilage are proton density-weighted, intermediate-weighted images and T2-weighted images with and without fat saturation and 3D fat-saturated T1 weighted images 3,4."

"Osteochondral autograft transplantation surgery was initially conducted in small chondral defects of the knee but has been used in multiple other joints like the hip, ankle, shoulder and elbow in the meantime. Also, smaller osteochondral defects can be treated with technique 1. The typical indication is active younger patients with smaller ("
