Therefore, meniscus tears that occur near the peripheral rim are able to heal after a meniscal repair. [1] One study found that repair is better than removal (meniscectomy). The amount of rehabilitation time required for a repair is longer, but removing the meniscus can induce osteoarthritis. Meniscectomy rehab requires four to six weeks.
The meniscus is a C-shaped piece of fibrocartilage located at the peripheral aspect of the knee joint that offers lubrication and nutrition to the joint. Each knee has two menisci, medial and lateral, whose purpose is to provide space between the tibia and the femur, preventing friction and allowing for the diffusion of articular cartilage.
Arthroscopy (also called arthroscopic or keyhole surgery) is a minimally invasive surgical procedure on a joint in which an examination and sometimes treatment of damage is performed using an arthroscope, an endoscope that is inserted into the joint through a small incision. Arthroscopic procedures can be performed during ACL reconstruction.
Arthroscopic meniscus surgery is one of the most common (and profitable) surgeries out there. If a meniscus tear appears on your MRI - a common recommendation will be surgery.
Arthroscopic lavage is a "cleaning up" procedure of the knee joint. This short-term solution is not considered as an articular cartilage repair procedure but rather a palliative treatment to reduce pain, mechanical restriction and inflammation. Lavage focuses on removing degenerative articular cartilage flaps and fibrous tissue.
The International Cartilage Repair Society has set up an arthroscopic grading system by which cartilage defects can be ranked: grade 0: (normal) healthy cartilage; grade 1: the cartilage has a soft spot, blisters, or superficial wear; grade 2: minor tears of less than one-half the thickness of the cartilage layer
