Overview

ACL Tear
An ACL tear is an injury to the anterior cruciate ligament, one of the major ligaments that stabilizes the knee. It commonly occurs during sports or activities involving sudden stopping, changing direction, landing from a jump, or a direct blow to the knee. A tear may cause a popping sensation, pain, swelling, reduced range of motion, and a feeling that the knee is unstable.
Degenerative Disc Disease
Degenerative disc disease refers to changes in the spinal discs that occur as they lose water, flexibility, and structural strength over time. These changes can sometimes cause back or neck pain, stiffness, or other symptoms. Disc degeneration can occur with aging and may also be influenced by injury or repeated stress. Degenerative disc disease does not necessarily cause symptoms, and disc changes seen on imaging are common as people age. When symptoms occur, they may include localized back or neck pain, stiffness, or pain that extends into an arm or leg when nearby nerves are affected. Symptoms can fluctuate over time.

Diagnosis

ACL Tear
An ACL tear is diagnosed using the injury history and a physical examination of the knee. Tests such as the Lachman test and other stability maneuvers can indicate ligament injury. MRI may be used to confirm the diagnosis and identify associated damage to the meniscus, cartilage, or other ligaments. X-rays may be performed to check for fractures or other bone injuries.
Degenerative Disc Disease
Diagnosis is based on symptoms, medical history, and a physical examination. Imaging such as X-rays or magnetic resonance imaging may show disc-space narrowing, changes in the discs, or other spinal abnormalities. Imaging findings do not always correspond directly to the severity of pain. Imaging findings can include disc-space narrowing, changes in disc shape, bone spurs, or other degenerative changes. MRI can provide more information about discs and nerves when neurological symptoms are present. A careful clinical examination remains important because degenerative findings may occur even in people without significant pain.

Prevention

ACL Tear
ACL injuries may be reduced through structured injury-prevention programs that include strength training, balance exercises, agility work, and instruction in safe jumping and landing techniques. Proper warm-up and conditioning are important before sports. Training that improves control of the hips, knees, and core may help reduce excessive forces on the knee during cutting, landing, and sudden changes in direction.
Degenerative Disc Disease
Disc degeneration cannot always be prevented because aging is a major contributor. Regular physical activity, maintaining a healthy weight, using safe lifting techniques, avoiding smoking, and protecting the back from repeated injury may help reduce strain on the spine. Regular strengthening and flexibility exercises can support the muscles surrounding the spine. Proper lifting technique, ergonomic work practices, maintaining a healthy weight, and avoiding tobacco can reduce modifiable stress on spinal structures. People with recurring symptoms should address contributing physical activities rather than repeatedly working through severe pain.

Risk Factors

ACL Tear
Risk factors include participation in sports involving cutting, pivoting, jumping, or rapid changes in direction, such as football, basketball, soccer, and skiing. Previous knee injury, inadequate conditioning, poor landing or movement mechanics, and muscle weakness may increase risk. Differences in anatomy and neuromuscular control can also influence susceptibility to ACL injury.
Degenerative Disc Disease
Risk increases with aging, repeated spinal stress, physically demanding work, heavy lifting, previous spinal injury, smoking, and excess body weight. Certain activities or occupations that place repeated strain on the spine may accelerate disc degeneration. Risk may be greater with advancing age and repeated loading of the spine. Heavy physical work, repetitive bending or lifting, prolonged vibration, previous spinal trauma, smoking, and excess body weight can contribute. Genetic differences may also influence how quickly discs undergo degenerative changes.
