Subchondral Bone Lesion Scores and Grades Measured by Magnetic Resonance Imaging (MRI).

<p>Data (n = 20 knees) are expressed as means±SDs. Scores are expressed as the summation of grades, and the grades as an average of the grades obtained for each region. Incidences of the lesions in subregions are indicated in parentheses (number of rabbits with lesions on medial/lateral femoral condyles/trochlea, medial/lateral tibial plateaus, or femoral condyles/tibial plateaus in the compartments).</p><p>Femoral condyles and trochlea score: week eight compared to weeks four and two,</p>§<p><i>p</i> = 0.000; week four compared to week two,</p><p>^*<i>p</i> = 0.001.
