Sleeve fracture of the patella Sleeve fracture of the patella. A: A small segment of the distal pole of the patella is avulsed with a relatively large portion of the articular surface. B: Lateral radiograph of the knee with a displaced sleeve fracture of the patella. Note that the small osseous portion of the displaced fragment is visible, but the cartilaginous portion is not seen.
