Arthroscopic meniscus surgery is one of the most common procedures in Orthopedics and Sports Medicine. The European Meniscus Consensus provides recommendations for the treatment of both acute meniscus tears and degenerative meniscus lesions, with full recommendations available for download from the ESSKA website. When planning surgery, it is crucial to look for associated pathologies, such as anterior cruciate ligament tears or cartilage damage. Proper portal placement is essential for a successful procedure and should be carefully planned. Arthroscopy typically begins with the anterolateral portal for the insertion of the arthroscope, followed by the placement of the anteromedial portal under direct vision, with additional portals added as needed during the procedure. The success of the repair depends on the size and location of the meniscus tear. The all-inside technique is the safest for repairing the posterior meniscus horn, while the outside-in technique is well suited for the intermediate and anterior portions of the meniscus.
