Sudden Knee Weakness? Learn the Signs, Causes & How to Treat It

When the knee becomes unstable or weak suddenly, it is most likely due to a fundamental problem with the knee. It may be a difficult muscle, or a piece of the protective tissue that keeps the joint in a flat position that has not been anticipated. Weak knees are not known to have a specific cause, but they may be related to an underlying autoimmune disorder. 

Knee inflammation can also lead to swelling and difficulty walking and standing for an extended period of time. The knee pain location chart can be used to easily identify where inside knee pain occurs as a result of weak knees.

Causes Of Sudden Knee Weakness Or instability

 Knees are complex joints, but they can perform a great variety of movements. During walking, running, squatting, and climbing stairs, many muscles cross over the knee joint. Our daily chores force our knee joints to work continuously throughout the day, so it is not surprising to experience knee weakness or instability suddenly.

There are several causes of sudden knee weakness

Weak Muscles 

Muscles will weaken if they do not receive proper physical activity in their daily routine. Quadriceps, hamstrings, and gastrocnemius muscles play an important role in knee stability. This weakness may result in conditions such as a looser knee joint, which may lead to knee weakness and buckling.

Torn Ligament 

When the torn knee ligaments do not heal properly, a person who has previously suffered a torn PCL or LCL will experience sudden knee weakness. When ligaments are weak, they affect the functions of stability in the knee.However, you cannot be sure until you consult with a medical professional whether you have a current LCL tear if your knees are weak.

Arthritis 

Osteoarthritis of the knee joint is only a matter of time before we develop it. Sports persons and runners who put a lot of strain on their knees in their youth will eventually develop this condition.Untreated arthritis can cause the knees to buckle and lock.

How Are Weak Knees or Knee Instability Diagnosed?

Detailed medical histories, physical examinations, and imaging studies are required to diagnose weak knees or knee instability.

Physical Examination

In order to detect ligament and meniscus tears, there are several tests that can be performed:

• McMurray’s test- rotation of the knees is performed to identify tears in the joint.

• Ege’s test- A clicking sound is heard when the patient squats.

Additionally, if you experience severe pain when moving your knee, you may have a locked knee.

Imagining Tests

X-rays are performed to determine whether a dislocation or ligament injury has occurred.
