Meniscus Tear
A meniscus tear is a common knee injury that involves the tearing of the fibrocartilage meniscus in the knee joint. The menisci are C-shaped pieces of tough, rubbery cartilage that act as shock absorbers between the thighbone (femur) and shinbone (tibia). They help distribute body weight across the knee joint and stabilize the knee during movements.
1. Acute Trauma: Sudden twisting or rotating of the knee joint while bearing weight, common in sports activities.
2. Degenerative Changes: Gradual wear and tear over time, often seen in older adults.
3. Age-Related Changes: The meniscus weakens and becomes more brittle with age, making it prone to tears.
1. Pain: Immediate pain at the time of injury, which may worsen with walking or bending the knee.
2. Swelling: Swelling around the knee joint, typically within 24 to 48 hours after injury.
3. Stiffness: Difficulty fully bending or straightening the knee.
4. Popping Sensation: Some individuals may hear or feel a pop at the time of injury.
5. Locking or Catching: Feeling of the knee joint locking or catching during movement.
