Orthopaedic Surgeon
The meniscus acts like a shock absorber in the knee. They are C-shaped, and each knee has a meniscus on the inside (medial) and outside (lateral). An acute traumatic knee injury can cause the meniscus to tear. A torn meniscus may cause secondary cartilage damage, knee swelling, locking, or clicking.
Sometimes with age, the quality of tissue within the meniscus declines. This can cause the meniscus to tear even in the absence of any trauma. This is referred to as a degenerative tear.
