Types and symptoms of damage to the menisci
Distinguish full and incomplete, longitudinal and lateral meniscus ruptures, and fragmented and locutores.
Injuries to the meniscus has both acute and chronic. In the acute period to make an accurate diagnosis quite difficult, because this injury is always combined with damage to other parts of the knee – ligaments, body fat, cartilage, capsules.
