• Analyses of Degeneration of Lateral Meniscus in Medial Compartmental Osteoarthritis of the Knee (OA) with MRI.

抄録

We examined the degeneration of the lateral meniscus (LM) by MRI in 47 knees with OA. The average age of the patients was 65.5 years (range from 47 to 90). They were divided into two groups radiographically by Kellgren classification: One group was classified as early stage, consisting of grades I and II, and the other as advanced stage, consisting of grades III and IV. There were 22 knees in the early stage, and 25 in the advanced stage. The MRI findings were evaluated according to Mink's classification. Grades 3A and 3B were regarded as significant degeneration.<br>In the early stage, a significant degenerative area was observed in the anterior, middle, and posterior regions in LM at the rate of 18.2%, 9.1%, 13.6%, respectively in MRI. On the other hand, in the late stage, the degenerative area was observed in the anterior region at the highest rate of 48%; In the middle and posterior regions, the rate was 28% and 24%, respectively. The tendency for the anterior region in LM to degenerate more frequently in the late stage may be correlated with the loose attachment to the capsular ligament in the subpopliteal recess in the posterior region.
