case_images: Clinical examination of the right knee revealed a limited range of motion (20-100o), joint line tenderness and crepitus, without any joint effusion or ligament instability (Figure 1).
case_images: Radiographic images of the right knee. Coronal view (A), sagittal view (B). The arrows point to the cystic formations in the proximal tibia and lateral distal femoral condyle

case_images: Radiographic images of the right knee displayed cystic formations in the proximal tibia and lateral distal femoral condyle, along with reduced medial joint space, subchondral sclerosis, and osteophyte formation (Figure 2).
case_images: MRI of the right knee. T2-weighted sagittal view (A), coronal view (B). T1-weighted sagittal view (C), coronal view (D). The arrows point to the location of the intra-articular tophi. MRI: magnetic resonance imaging
