Anterior Cruciate Ligament Tear

An anterior cruciate ligament (ACL) tear is a common sports injury that affects the knee joint. The ACL is a strong band of tissue that connects the femur (thigh bone) to the tibia (shin bone) and helps stabilize the knee joint. When the ACL is torn, the knee loses stability, making it difficult to walk, run, or engage in other physical activities.


ACL tears usually occur during activities that involve sudden stops, changes in direction, or jumping. Athletes who play sports like basketball, soccer, football, and skiing are at higher risk of ACL tears. However, ACL tears can also occur during non-contact sports or activities, such as dancing or gymnastics. In some cases, ACL tears can occur due to a direct blow or trauma to the knee.


The most common symptom of an ACL tear is a popping sensation in the knee, followed by immediate swelling and pain. The knee may also feel unstable, and the person may have difficulty walking or putting weight on the affected leg. Some people may also experience a feeling of giving way or buckling in the knee.


Diagnosing an ACL tear usually involves a physical exam, medical history, and imaging tests. During the physical exam, the doctor will check the knee for swelling, tenderness, and instability. They may also perform special tests to assess the integrity of the ACL.

Imaging tests, such as X-rays, MRIs, or CT scans, can help confirm the diagnosis and determine the extent of the injury. MRI is the most commonly used imaging test for ACL tears, as it can provide detailed images of the soft tissues in the knee joint.


The treatment for an ACL tear depends on the severity of the injury and the individual's activity level. In some cases, conservative treatment, such as rest, ice, compression, elevation (RICE), and physical therapy, may be enough to manage the symptoms and improve the knee's stability.

For more severe tears, surgery may be necessary to repair or reconstruct the ACL. ACL reconstruction surgery involves replacing the torn ligament with a graft from another part of the body or a donor ACL reconstruction in south Delhi. The surgery is usually done using minimally invasive techniques, such as arthroscopy, which involves making small incisions in the knee and using a camera and specialised instruments to perform the surgery.

After surgery, the person may need to use crutches for a few weeks and wear a knee brace or immobilizer to protect the knee. Physical therapy is also an essential part of the recovery process, as it helps restore the knee's strength, flexibility, and range of motion.


Although ACL tears cannot always be prevented, there are steps that can reduce the risk of injury. These include:

  • Wearing proper footwear and equipment for the sport or activity

  • Using proper techniques for jumping, landing, and pivoting

  • Building up the muscles around the knee joint through strength training and conditioning

  • Warming up before engaging in physical activity and cooling down afterwards

  • Avoiding high-risk activities, such as jumping from heights or landing on hard surfaces


An ACL tear can be a painful and debilitating injury that can affect a person's ability to engage in physical activities. However, with proper diagnosis and treatment, most people can recover from an ACL tear and return to their normal activities. Preventive measures can also reduce the risk of ACL tears and other knee injuries, allowing people to stay active and healthy for years to come.
