Abstract:

BACKGROUND: Magnetic resonance imaging (MRI) makes up for a deficiency of X-ray plain films and CT images in cartilage imaging, and can be involved in early diagnosis of bone bruise and cartilage injury.
OBJECTIVE: To explore the value of MRI in diagnosis of articular cartilage injuries complicated with bone bruise of the distal femur.
METHODS: Thirty-five cases of articular cartilage injuries complicated with bone bruise of the distal femur diagnosed by MRI were examined under arthroscopy.
RESULTS AND CONCLUSION: The site of articular cartilage injuries complicated with bone bruise of the distal femur examined under arthroscopy corresponded to MRI findings. The injuries showed by arthroscopy were in direct proportion to MRI. MRI plays an important role in evaluating articular cartilage injuries complicated with bone bruises, and bone bruises are considered as an indication of articular cartilage injuries. While sometimes MRI cannot deliver the severity of cartilage injuries because of instrumental factors.
