Damage to knee, knee joint, and/or surrounding support structure, including the anterior cruciate ligament (ACL), other ligaments, tendons, bone, and cartilage. May be caused by traumatic impact, sudden twisting motion, overload, overuse, or excessive wear. Not uncommon in sports such as soccer, basketball, volleyball, skiing, and snowboarding, and due to vigorous exercise (eg, military and sports performance training). Also seen in physically demanding occupations.

May be associated with osteoarthritis, low bone density, musculoskeletal or neurologic disorder, patellofemoral pain syndrome, or a fall.

The general category of knee injury may be divided into ligamentous injuries, sprains, contusions, dislocations, fractures, and cartilage, meniscus, or tendon injuries.

Characterized by knee pain, swelling, inability to bear weight, limited range of motion, limp, deformity, clicking, grinding (crepitus), catching, stiffness of knee, and knee instability.

Management depends on the type and severity of injury and ranges from icing and bracing to arthroplasty and total knee replacement. Most injuries call for physical therapy and medications for pain, swelling, or infection.
