How is multi-ligament knee reconstruction performed?
Prior to operating on the knee, Dr. Provencher performs an examination under anesthesia to confirm the damaged ligaments and verify the integrity of the other knee ligaments. A tissue graft is then harvested from the patient, or donor tissue is used. When the tissue grafts are prepared, Dr. Provencher makes a few small incisions surrounding the knee and introduces a small camera (arthroscope) to methodically examine the muscles, ligaments, and tendons of the knee. The damaged fragments of the ligaments are identified and removed with specialized surgical instruments. The tissue grafts are then carefully situated in the same anatomical position as the native ligaments to ensure a successful recovery. Once the necessary revisions are complete, the repaired ligaments are assessed for good tension, and stability and range of motion of the knee is evaluated. The arthroscope and surgical instruments are withdrawn from the knee joint and the incisions are closed with steri-strips or sutures.
Because of the complexity of this surgical procedure, Dr. Provencher may combine the arthroscopic surgical approach with an open surgical technique. The larger incision of an open surgery enables Dr. Provencher to visualize the entire knee joint while completing the necessary revisions. Whether this surgery is completed using one surgical technique, or a combination of surgical methods, Dr. Provencher prefers to complete this surgery in one setting to provide the patient with the best possible recovery outcome.
