knee arthroscopy


Arthroscopic surgery makes it possible to carry out therapeutic gestures in a joint without making large scars, by making only "small holes"


Through small incisions, a camera and instruments are introduced and manipulated into the joint cavity.

A circulation of physiological fluid is established and maintained throughout the intervention, so as to guarantee optimal vision on a video screen.

Here is the kind of image that is obtained during a knee arthroscopy:


^ articular facet of the patella, with in the background a cannula which serves to evacuate the rinsing liquid.


​^ above, the femoral part of the joint, covered with intact cartilage ; below, the cartilaginous surface of the tibia, also in good condition; in the middle, the meniscus, which has a tear.


^ Degenerative lateral meniscus, with at bottom the tendon of the popliteal muscle running through the joint.


^ meniscus undergoing partial resection, with a degenerative part (in yellow).


^ torn meniscus tab pulled apart by a hook.

What are the knee operations that can be performed by arthroscopy?

  • meniscus surgery

  • anterior cruciate ligament plasty

  • intervention on the cartilage (smoothing, grafting, etc.)

  • removal of "joint mice"

  • synovectomy for rheumatoid or inflammatory arthritis

The duration and nature of postoperative rehabilitation vary according to the type of operation; for the meniscus, the patient can get up immediately after the operation and walk fully weight-bearing, using crutches for a week; there is no need for a splint or cast. For operations on the cruciate ligaments and cartilage, rehabilitation is longer and more complicated.
