CPT® Code 27333

The procedure described by CPT® Code 27333 involves an arthrotomy, which is a surgical incision into the knee joint, combined with the excision of semilunar cartilage, commonly known as a meniscectomy. This specific procedure is indicated for patients with a torn meniscus that is deemed irreparable. The meniscus is a C-shaped cartilage that acts as a cushion between the femur and tibia in the knee joint, and tears in this cartilage can lead to pain, swelling, and impaired joint function. In cases where the tear extends into a non-vascular region, where healing is unlikely even with repair, excision becomes necessary. The surgical approach begins with a skin incision over the knee joint, followed by careful dissection of surrounding tissues to expose the joint capsule. Once the capsule is opened, the knee joint is thoroughly flushed with saline solution to clear any debris, allowing for a clear view of the meniscal tear. The surgeon then examines the joint, locates the tear, and assesses its extent using a small hook. The damaged portion of the meniscus is resected using various surgical instruments, ensuring that only the affected tissue is removed. After addressing any tears in both the medial and lateral compartments of the meniscus, the remaining meniscal edges are smoothed, and the joint is flushed again before closure. This procedure is critical for restoring knee function and alleviating pain associated with meniscal injuries.
