CPT® Code 27380

The procedure described by CPT® Code 27380 involves the surgical suture of the infrapatellar tendon, which is more accurately classified as a ligament connecting the tibia (shinbone) and the patella (kneecap). This tendon plays a crucial role in the stability and function of the knee joint. The surgical approach begins with a midline incision that extends from the top of the patella down to the medial aspect of the tibial tubercle, allowing for adequate exposure of the area. During the procedure, medial and lateral flaps are created to facilitate exploration of the surrounding structures, specifically the medial and lateral retinacula, which are connective tissues that support the knee. Once the surgical site is adequately exposed, the torn infrapatellar tendon is identified and mobilized for repair. Debridement, which involves the removal of damaged tissue, is performed on the torn tendon, and depending on the location of the tear, additional debridement may be necessary on the tibial tubercle and/or the inferior pole of the patella. The next step involves placing sutures in the torn tendon, followed by preparing the bony surfaces of the tibial tubercle and/or inferior pole of the patella. This preparation may include drilling tunnels or placing suture anchors to facilitate the secure attachment of the tendon to the bone. The sutures from the tendon are then passed through these tunnels or anchors, effectively securing the infrapatellar tendon to the bone. In some cases, a second drill hole may be created in the tibial tubercle, allowing for a suture to be passed from the tibial tubercle through the quadriceps tendon at the upper pole of the patella. This step is critical for evaluating and ensuring the correct patellar height, which is essential for optimal knee function. Once the appropriate height is confirmed, the sutures of the infrapatellar tendon are tied off to secure the repair. The procedure concludes with irrigation of the wound and closure of the incision, ensuring a clean and secure surgical site. For cases requiring a secondary suture repair of the infrapatellar tendon, including the use of fascial or tendon grafts, CPT® Code 27381 should be utilized, which involves a different surgical approach to address the defect.
