Magnetic resonance imaging (MRI) of the right knee with and without contrast acquired on day +49 before surgery (A. and B.), and day +195 after initial debridement in the joint space and the medial tibial plateau (B. and C.). Fat suppressed proton density (FS-PD) MRI sequences demonstrating osteomyelitis within the lateral femoral condyle (Labeled with “*”; A. and C.). T-2 weighted MRI sequences demonstrating medial tibial plateau osteomyelitis with abscess 2.3 × 1.3 × 0.3cm, and post-debridement changes (Labeled with arrows; B. and D., respectively).
