A meniscal injury refers to damage to the meniscus, a cartilage structure in the knee joint that cushions between the thigh bone (femur) and shin bone (tibia). This type of injury commonly occurs during sports or activities that involve sudden twisting or pivoting movements. Symptoms may include pain, swelling, difficulty moving the knee, and a clicking or locking sensation. Treatment options vary depending on the severity of the injury and may include rest, physical therapy, pain medications, and in some cases, surgery to repair or remove the damaged meniscus.
