Anterior cruciate ligament (ACL) is one of the four major ligaments of the knee and a crucial component of the extracapsular knee joint stabilizers.
Anterior Cruciate Ligament (ACL) is a ligament in the knee that helps connect the tibia with femur. It works to stabilize the knee by transmitting tension and weight to the femur. The ACL can be easily torn if the knee suffers an injury usually a sudden force that causes it to bend in an uncoordinated way or twist.
This ligament is responsible for keeping the shin bone from sliding forward under the thigh bone. If this happens, it can lead to pain and injury in your knee joint.
The ACL prevents hyperextension of the knee, which can cause damage to other areas of your body such as cartilage or meniscus tissue surrounding bones in your legs (or both). If you tear an ACL, you may notice pain behind or around your knee when using it. Your doctor will be able to diagnose whether or not you have torn your ACL by performing physical examinations as well as diagnostic tests such as MRI scans or X-rays (which are used to view bones).
The ACL can be injured during sports and other activities in which you twist or pivot on your knee. It can also be damaged as a result of certain medical conditions, such as osteoarthritis and rheumatoid arthritis.
The ACL can be injured when you place too much stress on it. This typically happens during sports or other physical activities.
An ACL injury usually causes immediate pain and swelling in the knee joint. You may feel like something has “gouged” your knee or that it’s unstable when you stand up from sitting or bend forward from a standing position.
There are many causes of ACL injuries, including:
Age-related changes: As people age, they become more likely to experience ACL injuries. This is because as you get older, your bones become less dense, which makes them more prone to breaking or fracturing. Older people who participate in sports activities may be at a higher risk for ACL injuries due to the increased impact on their knees.
Anatomical factors: Some people may have anatomical variations that make them more susceptible to ACL injuries, such as having wider hips or being bow legged or knock-kneed. These anatomical differences can lead to misalignment in the knee joint and improper alignment of the lower leg bones which increases stress on the ligament during activity or exercise sessions. This can result in tearing or rupturing over time if not addressed properly before starting new workouts/activities that place stress on these areas (like running).
The symptoms of an ACL injury can vary from person to person, depending on how severe the injury is and where it occurred in the ligament.
Symptoms of ACL injuries include:
-Pain and swelling around your knee joint
-Difficulty walking or moving your knee
-Inability to squat down without pain
-A feeling that the knee is “giving way”
-Sudden, sharp pain in the knee when you try to run or jump (or even when you walk up stairs)
If you have a history of ACL injuries, there are several ways to prevent further injuries.
First, be sure to strengthen your quadriceps muscles. This will help support your knees and can help prevent ACL injuries.
You should also do exercises that strengthen the muscles around the knee joint. These include squats and lunges for lower body strength and hip bridges for upper body strength.
You should also avoid activities that put strain on your knees or require quick movements or jumps. These include football, basketball, soccer, volleyball, track and field events as well as downhill skiing and skateboarding.
There are three main treatments for ACL injuries: surgery, non-surgical treatment and conservative treatment.
Surgery is the most common treatment for ACL injuries, but it can also be the most expensive. It involves replacing the torn ligament with a tendon graft from another part of your body or from a cadaver.
The surgery is usually done as a single procedure, though you may need to have additional surgeries later on if there are complications or problems with healing.
Non-surgical treatments include physical therapy and bracing. Physical therapy is often used to help you regain strength in your muscles around the knee and strengthen your leg muscles so they will support your knee joint better. Bracing can help keep your knee stable while it heals.
A brace will prevent you from moving your knee too much so you don’t put any pressure on it that could cause further damage until it’s healed enough to move around normally again without pain or discomfort while still protecting against further injury during everyday activities like walking or running outdoors when it snows outside during winter months (cold weather).
Conservative treatment means using medicines that relieve pain and swelling without surgery or other invasive procedures (elevation above heart level whenever possible).
