Radiology 2018; … Osteochondritis dissecans (OCD) includes a spectrum of joint disease involving articular cartilage, 1,6,12,26 with the subchondral bone lesion having the potential to progress to varying degrees of osseous resorption, collapse, detachment, and violation of the overlying articular cartilage, which may result in intra-articular loose body formation. A cell-free biomimetic osteochondral scaffold showed positive results in adult patients. Purpose: To retrospectively compare the sensitivity and specificity of previously described magnetic resonance (MR) imaging criteria for the detection of instability in patients with juvenile or adult osteochondritis dissecans (OCD) of the knee, with arthroscopic findings as the reference standard. Healing predictors are needed to identify potential failures and thus determine treatment options.
