Posttraumatic Cartilage Calcification of the Knee: A Case Report

Abstract

A 24-year-old woman presented with a calcium deposit within the articular cartilage of her knee after an antecedent minor trauma. Arthroscopic examination revealed the articular surface of the lateral tibial plateau yielded easily to pressure by probing. Calcium-containing crystals within the articular cartilage was identified and debrided. Magnetic resonance images taken 4 years after operation showed the articular cartilage was completely repaired. This is the first report that demonstrated a painful well-defined calcium deposit detected by conventional radiography within the articular cartilage of the knee.
