CPT® Code 29888

The procedure described by CPT® Code 29888 involves an arthroscopically aided repair, augmentation, or reconstruction of the anterior cruciate ligament (ACL) in the knee. The ACL is a critical ligament located in the center of the knee joint, connecting the femur (thigh bone) to the tibia (shin bone). It plays a vital role in providing stability and controlling rotational movements of the knee. Injury to the ACL can lead to significant instability, causing the knee to buckle during activities. This procedure is performed using an arthroscope, a specialized instrument that allows the physician to visualize the inside of the knee joint through small incisions, known as portals. Typically, three or more portal incisions are made to facilitate the introduction of the arthroscope and surgical tools. The knee joint is flushed with saline to clear any debris, and the physician examines the meniscal cartilage and the condition of the ACL. If a tear is identified, the damaged ACL is either repaired or reconstructed. The procedure may involve harvesting a graft from the patellar tendon, which is then used to replace the torn ACL. The surgical steps include creating drill holes in the tibia and femur to secure the graft, ensuring proper alignment and stability of the knee joint post-surgery. This minimally invasive approach aims to restore function and stability to the knee while promoting a quicker recovery compared to traditional open surgery.
