Chapter 102 describes indications, technique, and imaging findings of knee arthrography. Knee arthrography is selectively performed in clinical practice for MRA, typically in younger patients. Indications include evaluation for meniscal re-tear after prior repair, osteochondral injuries, and therapeutic injections (most commonly steroid). Extension of intraarticular contrast into the meniscal substance indicates a tear or re-tear. Abnormal course of the cruciate ligament fibers indicates a tear. Contrast undermines unstable osteochondral lesions and extends into the hyaline cartilage defects. Complications are rare but include infection and bleeding.
