case_images: (a, b) X-ray images of a fracture fragment within the knee joint. (c) Patellar morphology is not abnormal, but the groove is slightly shallow and dislocation can be observed with external rotation stress of the knee and push to patellar.

case_images: fig1
case_images: The patellar morphology was not abnormal, but the groove was slightly shallow, and dislocation was observed with external rotational stress of the knee and push to the patella (Figure 1).
case_images: CT images of an osteochondral defect in the posterior portion of the lateral femoral condyle (LFC), as indicated with the arrow. (a) Coronal section and (b) sagittal section.

case_images: fig2
case_images: Computed tomography (CT) revealed an osteochondral defect in the posterior portion of the LFC (Figure 2) and an avulsed bone fragment within the femoral patellar joint.
case_images: MRI images of the medial patellofemoral ligament (MPFL) injury (arrowheads) and slight bone bruises on the patella (arrow).

case_images: fig3
case_images: Magnetic resonance imaging (MRI) showed a medial patellofemoral ligament (MPFL) injury and slight bone bruises on the patella and LFC (Figure 3).
case_images: Arthroscopy images. (a) An osteochondral defect in the LFC. (b) Damage to the lateral meniscus on the femoral side. (c) Osteochondral fragment with anatomical reduction and fixing.

case_images: fig4
case_images: Arthroscopy revealed an osteochondral fragment in the femoral patellar joint and an osteochondral defect in the LFC (Figure 4(a)). The lateral meniscus was damaged on the femoral side (Figure 4(b)). Arthroscopy confirmed that the osteochondral fragments were anatomically reduced and fixed (Figure 4(c)).
case_images: CT images showing good bony fusion and no joint step. (a) Coronal section and (b) sagittal section.

case_images: CT confirmed good bony fusion and no joint step (Figure 5).
case_images: MRI image showing the reconstructed MPFL, as indicated with the arrow.
