Arthroscopy is a surgical technique by which an optical instrument connected to a camera is inserted into a joint to visually explore it (knee, shoulder, hip, fist, etc.). The joint is inflated with a sterile fluid. This intervention is carried out in a liquid environment, which allows perfect preservation of ligaments and cartilage. Intervention is viewed on a monitor.
The most used arthroscope has 5 mm in diameter and is inserted into the knee via a small incision (1 cm). The intervention is conducted under anaesthesia. One or two other small incisions are necessary to insert the instrumentation and remove the intra-articular fluid.
With this minimally invasive technique, e.g. at the knee, one can remove a part of the meniscus or suture it, remove a part of the cartilage or graft the areas of necrosis, reconstruct the internal ligaments of the knee.
This technique is less traumatic to the tissue than “open” surgery techniques and recovery after intervention is quicker. There are also other advantages: aesthetic scar, no blood loss, tissue less traumatized, shortened length of hospital stay. The patient is able to leave the hospital the same day and can support on the operated leg (except for complex interventions).
