An arthroscopy is a surgical procedure that can visualize, diagnose and treat problems inside joints, like the knee, elbow and ankle. It is a minimally invasive surgery that with the help of an arthroscope allows to see inside the joints. That is why a Knee arthroscopy can be done in several cases and not only for one specific condition. As mentioned before it is possible to do an arthroscopy, but is commonly done on the shoulder, elbow, knee, wrist, ankle and hip.
A surgeon will make two little incisions on the knee; one to let the arthroscope in, and allow the surgeon to see inside and make his diagnose, the other one is to introduce the surgical instruments to be used in the cavity.
By making only two little incisions, the recovery process is shorter, and allows the patient to be back on regular activities in a couple weeks, although is normal to see the results on up to 6 weeks, that is the time the joint will be completely functional again.
