Arthroscopy, a minimally invasive orthopedic surgery technique, is the set of procedures that allow access to the joint, through two or three mini incisions, to visualize problems inside joints, cartilages, ligaments and tendon insertions, using a fiber optic light source attached to a camera located in front of the orthopedic surgeon. Besides diagnosis, this technique enables surgeons to perform biopsies, suctions and/ or surgical procedures using mini instruments, instead of a single large incision along the joint. Arthroscopic surgery is becoming increasingly widespread in Tunisia, for it is getting increasingly mastered in terms of interventional accuracy and it ensures minor post-operative effects and a lower complication rate.
