Magnetic resonance imaging in the evaluation of sequelae after tibial plateau fractures.

Abstract

Nine knees with persistent radiographic depression of the articular surface after tibial plateau fractures treated by traction and early knee motion were examined using magnetic resonance imaging (MRI). The MRI examinations demonstrated that the radiographic bone defects were filled up with different tissues, which we interpreted as cartilage, fibrous tissue and synovial plica. The type of tissue in the bone defect did not seem to affect the functional capabilities of the knee. However, a demonstrable thin cover of tissue, with the signal-intensity of cartilage, over the defect, seemed to be associated with an excellent functional result.
