How is a partial meniscectomy performed?
Dr. Williams typically does these procedures arthroscopically. Arthroscopic surgery is a minimally invasive procedure that implements the use of a small surgical camera and small surgical tools, which are inserted through small incisions in the knee. The camera (arthroscope) projects images of the inside of the knee onto a monitor while Dr. Williams performs the surgery inside the knee. These procedures are typically very quick taking between 20-30 minutes to execute. Regional and local anesthesia is the norm for these procedures. Most patients can expect to go home the same day.
During a partial meniscectomy, Dr. Williams will remove any fragmented pieces of the menisci that are lodged in the knee joint. He will remove the damaged menisci and smooth any frayed areas of cartilage. The area of the meniscus that does not have blood supply is usually the driving factor behind a partial meniscectomy. Blood promotes healing, but the inner section of the meniscus (white zone) does not receive a blood supply. The outer section of the meniscus (red zone) has a blood supply and a better chance of self-repair. If the meniscus damage occurs in the outer third section, Dr. Williams may be able to repair the meniscus rather than removing the torn area.. The decision regarding removal or repair is made by Dr. Williams during the course of the procedure.
