The knee has two menisci: the medial and lateral meniscus. These structures are fibrocartilaginous rings that sit between the femur and tibia bone. They function during weight bearing to cushion the joint and protect the articular cartilage surfaces. Otherwise, the meniscus can become damaged and torn.
Symptoms of a torn meniscus are typically knee pain, joint swelling, limping, knee clicking or locking, an inability to run or perform at a previous baseline level of activity. Treatment for a torn meniscus in some cases is pain management. This can include the use of oral anti-inflammatory medications, steroid injections, knee bracing and exercises. In other cases surgical treatment is recommended.
