Getting Weak In The Knees? Causes, Symptoms And Treatment

There are actually two things that can truly get you weak in the knee, one is love and the other one is knee pain. We aren’t talking love here so let’s focus on causes, symptoms and treatment for weak knees.


A lot of our body weight is beared by our knee joint, so caring for it is critical. The strength of the knees is reduced by the everyday wear and tear causing pain and discomfort that inturn makes your knee go weak. 


If you are experiencing weak knees, take action to strengthen your weak knee joints.


Sudden knee weakness does not refer to weakness which may last over for a few minutes or hours or days. In most cases, weakness may have been coming on over weeks but has been discounted by you, and then apparently this sudden weakness that doesn’t go away.


You can experience weak knees due to illnesses, injuries or overuse. 


Some of the most common causes include:


  • Strains and sprains
  • Infection of the knee joint
  • Lack of physical activity
  • Iliotibial Band Syndrome

Major reasons that may lead to knee weakness are


  • Muscle Weakness – If your muscle joint lacks in receiving physical activity then over time your muscles will start to weaken. When muscles get weakened, it may lead to loose knee joint, which could lead to knee weakness and buckling.

  • Arthritis – All those people who tend to put a lot of strain on their knees will have to experience this condition sooner or later. Arthritis if not treated on time can turn into a critical condition which can lead to buckling and locking or the knees.

  • Torn ligament – A person with a torn PCL or LCL will experience sudden knee weakness if they don’t let their torn knee ligaments heal properly. 

  • Nerve damage – There are a number of conditions associated with nerve damage, including diabetes, chronic alcohol use and multiple sclerosis. It may cause a tingling or burning pain in the area around the knee.

Weak knee symptoms


The feeling of a knee going out may or may not be accompanied by the following signs and symptoms:


  • Popping
  • Clicking

  • Sticking
  • Grinding
  • Pain
  • Bruising
  • Joint stiffness
  • Reduce range of motion

Treatment for weak knees


The treatment of knee instability depends on the specific cause of the symptoms. The overall goal is to treat pain and restore strength and the function of the joint. Treatments may include:


  • RICE (rest, ice, compression and elevation)  
  • Anti-inflammatory medications for pain
  • Physical therapy and knee rehab exercises 
  • A knee brace or immobilizer
  • Strengthening program
  • Knee surgery

Knee conditions that have not been addressed increase the risk of the conditions that lead to instability.


The sensation of understanding that you might be actually having weak knees can be challenging, as there are many potential causes including it being a normal part of ageing. Fortunately, there are many different treatment options that can restore your knee function and reduce pain.
