CPT® Code 27415

The procedure described by CPT® Code 27415 refers to an osteochondral allograft for the knee, which is an advanced surgical technique aimed at repairing damaged articular cartilage. Articular cartilage is the smooth tissue that covers the ends of bones in joints, allowing for smooth movement and reducing friction. In cases where this cartilage is damaged due to injury or degenerative conditions, an osteochondral allograft can be utilized to restore the joint's function and alleviate pain. This procedure involves the use of cylindrical grafts taken from a donor, which are precisely shaped to fit the defect in the patient's cartilage. The surgical process begins with a skin incision over the affected knee compartment, followed by an incision of the joint capsule to allow for direct visualization of the knee joint. The surgeon inspects the joint to assess the extent of cartilage damage, measures the affected area, and determines the number of grafts needed for effective repair. The damaged cartilage is then carefully debrided and prepared to receive the allografts, which are sourced from a bone bank. After the grafts are implanted and stabilized within the defect, the surgeon checks the range of motion to ensure proper placement and stability of the grafts before closing the incisions. This procedure is critical for patients suffering from significant cartilage loss, as it aims to restore joint function and improve quality of life.
