Comminuted tibial plateau fracture with detachment of the intercondylar eminence and medial depression - Schatzker type V fracture.
The patella is in pronounced lateral tilt and subluxation.
Large lipohaemarthrosis.
The patella is in pronounced lateral tilt and subluxation.
Large lipohaemarthrosis.
Medial meniscus: normal height and signal.
Lateral meniscus: detached (meniscocapsular separation), flipped, translated to the centre of the knee, probably impacted in the plateau fracture.
Anterior cruciate ligament (ACL): normal thickness, course and signal; of note, detachment of the eminence with the ACL insertion.
Posterior cruciate ligament (PCL): normal thickness, course and signal.
Lateral meniscus: detached (meniscocapsular separation), flipped, translated to the centre of the knee, probably impacted in the plateau fracture.
Anterior cruciate ligament (ACL): normal thickness, course and signal; of note, detachment of the eminence with the ACL insertion.
Posterior cruciate ligament (PCL): normal thickness, course and signal.
Medial collateral ligament (MCL): normal thickness, course and signal.
Lateral collateral ligament (LCL): normal thickness, course and signal.
Lateral collateral ligament (LCL): normal thickness, course and signal.
Quadriceps tendon: normal thickness, course and signal.
Layers of muscle, fat planes, skin, and subcutaneous tissue: prominent oedema.
In summary:
- Complex tibial plateau fracture (Schatzker V)
- Detachment of the intercondylar eminence with the ACL insertion
- Lateral menscus separation, translation to the centre of the knee and apparent impaction between the fracture fragments
- Lateral tilt and subluxation of the patella
- Substantial lipohaemarthrosis
