Arthroscopy is the treatment of intra-articular lesions of the knee without opening the joint by passing through two small incisions, using miniaturized and thin instruments (approximately 3 to 4 mm). One of these passages is used for optics, which retransmits the images live inside the joint, and another for the passage of instruments specially designed to make their way through very small spaces. Knee arthroscopy now has a special place in the treatment of meniscal lesions, whether radical (simple resection of the meniscal lesion) or conservative (direct suture of the meniscal lesion).
Arthroscopic Knee Debridement
The constant evolution of this particular field of orthopedic surgery, now allows surgeons all around the world to perform ligament reconstructions, both at the level of the anterior cruciate ligament and posterior. For this, a large number of techniques exist and are selected according to the patient’s functional demand, factors such as weight, type of sports practice, etc., and the surgical habits of the surgeon.
Arthroscopic Knee Debridement is the most frequent intervention and is used either for a traumatic rupture such as while being injured during sports, or in case of a degenerative disease such as osteoarthritis. After the clinical examination, which usually confirms the lesion, possibly associated with an MRI, arthroscopy makes it possible to directly visualize the lesion and to treat it.
It can be either general or more often local. The anesthetic consultation and the preoperative assessment are compulsory before the operation. The average duration of the operation varies between 30 minutes (meniscus, kneecap, osteoarthritis), to 60 minutes (Anterior cruciate ligament).
In the first operative stage, the surgeon will observe the lesions of the tissues, cartilage, and bones. Then, they will perform a debridement, that is to say, cleaning of the joint to remove any micro-fragments. This intervention is normally performed on an outpatient basis or requires 1 day of hospitalization. However, for arthroscopic debridement of knee osteoarthritis up to three days of hospitalization may be needed.
