Radiographs and computed tomography (CT) showed small flecks of bone at the proximal tibial tuberosity (Figure 1).
(a) Left is affected side. (b) Right is healthy side. Magnetic resonance imaging (MRI) revealed swelling and loosening of the patellar tendon.

We also recognized patella alta in comparison with the right knee with a Sugimoto index of 1.36 (Figure 3).
Operative findings. The patellar tendon was avulsed with sleeve fragment from tibial tuberosity.

During the operation, we found that the patellar tendon was avulsed with a sleeve fragment from the tibial tuberosity (Figure 4).
The avulsed tendon was repaired using two suture anchors, and fragment including cartilage was attached by tension band wiring method.
