case_images: Surgical access with extensive exposition of the patella, which appears enlarged and deformed (A). The access was used to isolate the degenerated patella from the surrounding soft tissues (B).

case_images: A direct longitudinal approach to the anterior knee centered on the patella was performed: the skin incision was extended for about 25 cm to allow complete exposure of the patella and its surrounding tissues (Figure 2A). The patella was then isolated from the surrounding soft tissues while preserving the quadriceps tendon and patellar ligament (Figure 2B).
case_images: Pictures showing the anterior knee after the resection (A), After one the allograft had been sutured in its distal end and tunneled within the native quadriceps tendon (B) and once it had been completely sutured to restore the continuity of the extensor apparatus (C).

case_images: The removed patella (Figure 3A) was then delivered to our Pathological Anatomy division, which confirmed the presumptive diagnosis of skeletal localization of adenoid cystic carcinoma. Distally, the patellar ligament of the graft was set between the native ligament's medial and lateral segments and sutured with fiber wires (Figure 3B). Proximally we made a hole in the native quadriceps tendon, through which we passed the rolled proximal segment of the allograft quadriceps tendon (Figure 3C).
