CPT® Code 27420

The CPT® Code 27420 refers to the surgical procedure known as the reconstruction of a dislocating patella, commonly performed to address issues related to patellar instability. This procedure is particularly relevant for patients who experience recurrent dislocations of the patella, which can lead to pain, functional impairment, and decreased quality of life. The reconstruction aims to restore proper alignment and stability of the patella within the knee joint. The Hauser type procedure, a specific technique used in this surgery, involves a distal transfer of the tibial tuberosity, which is a bony prominence on the tibia where the patellar tendon attaches. By repositioning the tibial tuberosity, the surgeon can improve the tracking of the patella during knee movement, thereby reducing the likelihood of future dislocations. The procedure is performed through a lateral incision, allowing access to the necessary anatomical structures while minimizing damage to surrounding tissues. Overall, CPT® Code 27420 encapsulates a critical intervention for managing patellar dislocation and enhancing knee function.
