We use our knees throughout the day for a variety of activities, so it is not surprising that we may experience knee weakness or instability. A weak knee is also referred to as knee buckling. However, a weak knee may increase the risk of falling or suffering serious injury, so it is important to address the underlying cause as soon as possible. When your knees are weak, you may be unable to carry out the tasks required of you in your everyday life and for your job.

You may also be unable to engage in meaningful activities due to weak knees. Injury and pain to the knees are common occurrences. To help diagnose the cause of your knee pain, doctors use a knee pain location chart. Physicians often recommend strengthening the knee muscles. Several treatment options are available at Dr. Ali pain management for patients suffering from pain in their bodies.

Symptoms Of Weak Legs

• Pain in the joints may be acute and last for just a few days or it may be chronic and last for several months or even years. 

• The swelling of the knee occurs as a result of excessive fluid accumulation inside the joint due to an injury, overload, or chronic condition. Soreness and muscle spasms may result from this. 

• Getting up after relaxing for some time and hearing a cracking or crunching sound is an indication that your knees are weak. 

• Unable to straighten your knees.

What Are the Major Causes of Weak Knees?

A weak knee can be caused by a variety of factors, including injury, arthritis, obesity, and overuse. It does not matter what the cause of a patient's pain may be, a pain management doctor will be able to provide a treatment plan that is individually tailored to meet the needs of that patient.

Here are some of the major causes of weak knees: 

• Injuries or Tears

Injuries or ligament tears caused by high-impact activities like running can lead to weak knees or knee instability.

• Ligament Tears

Knee instability and weakness may be caused by ligament tears. Ligament tears may be partial or complete. Athletic activities often result in the injury of these ligaments. Overuse or a sprain can occur even in the simplest of daily activities. It may be necessary to seek medical attention depending on the severity of the ligament damage. 

• Meniscus Tears 

A meniscus is a cartilage pad. In a nutshell, they act as shock absorbers for the knee and assist in stabilizing it. When a person twists, turns, or pivots, a meniscus can be torn. Due to the weakening of the meniscus during that period, meniscus tears are common in individuals over the age of 30.

• Damage to the Nerves

As one of two major nerves in the lower leg, the femoral nerve is important. As it runs down the thigh and to the shinbone, the femoral nerve is located in the pelvis. An injury to the femoral nerve may cause a knee to feel as if it is giving out. Additionally, this causes tingling or burning sensations around the knee. An individual's femoral nerve may be damaged as a result of an injury, or as a result of pressure being applied to the nerve. 

• Plica Syndrome

As the name implies, PLICAS is a condition in which the inner lining of the knee joint is inflamed. Typically, it occurs when the individual bends. 

• Arthritis

An inflammatory condition affecting the joints, arthritis causes pain and swelling. Arthritis can be classified into several types. Osteoarthritis or rheumatoid arthritis may cause weak or inflamed knees. A variety of factors can also cause internal derangement of knee, including overuse, trauma, or degenerative changes caused by diseases such as arthritis. The knee joint may become painful, swollen, unstable, and difficult to move as a result of this syndrome.
