Abstract
Background: In the early stage, joint space is unclear narrow, it’s difficult to determine knee arthritis. Study of characteristics of magnetic resonance imaing in knee arthritis in oder to combine with Xray in dignosis knee arthritis.
Purpose: assessment of knee lesion on magnetic resonance imaing, to analyse the diagnosis value of cartilage degeneration as compare with arthroscopy.
Objects and methods: 30 patients with varus knee arthritis in Kellgren-Lawrence stage II, III, IV. MRI 1.5T and arthroscopy were performed after. Radiographs were classified according to Kellgren-Lawrence scale. MRI is classified according to Vallotton, and arthroscopic rading according to Outerbridge.
Result: on MRI: knee effusion is 96.66%, bone marrow edema in medial femoral condyle is 83.33%, medial tibia plateau is 60%, medial meniscus tear is 93.33%. Cartilage lesion in medial femoral condyle is 100%. Sensitivity of 83.52% and a specificity of 63.91% for the detection of femoral chondral lession.
Conclusion: In varus knee osteoarthritis, MRI 1.5 T identifies all lesions inside knee. We suggest that MRI is applied in identifying a group of patients who have degenerative joint disease, especially in early-stage knee osteoarthritis. Combination between clinical examination, weight-bearing plain Xray and MRI will detect the whole lesions in varus knee osteoarthritis.
