Knee Buckling occurs when one or both of your knees buckle. It is also known as knee instability or weak knees. While it is frequently accompanied by pain, it is not always the case. You may have simply stumbled if it has only happened once or twice.
What exactly is Knee Buckling?
Knee buckling can be a sign of a knee injury or damage. It can increase the risk of falling and make recovery from knee problems take longer.
Knee buckling is fairly common in adults. According to one study, 11.8 percent of adults aged 36–94 had at least one episode of knee-buckling in the previous three months. It can affect people of all ages and fitness levels.
Frequent knee-buckling increases your danger of falling and harming yourself severely, thus it’s critical to identify the underlying problem. Continue reading to find out more about the reasons for knee-buckling and how to cure it.
Knee Buckling Causes
1. Injury
Many occurrences of knee instability are the result of injuries sustained during high-impact activities such as jogging or in an accident. Knee injuries that are common include:
-
Tears in the ACL
-
Tears in the meniscus
-
Sloppy bodies (pieces of bone or cartilage floating within the knee)
-
Knee injuries often result in pain and edema in the afflicted knee, in addition to instability.
Injury-related knee-buckling generally resolves if the underlying injury is treated. Depending on the nature of the injury, you may need physical therapy or surgery. While you’re healing, try to avoid placing pressure on your knee as much as possible.
2. Damage to the Nerves
One of the two primary nerves in your lower leg is the femoral nerve. Femoral neuropathy, which refers to femoral nerve dysfunction, may induce knee weakness, making them more prone to buckling. Other femoral nerve neuropathy symptoms include:
-
Pain
-
Tingling
-
Burning
-
Tingling sensations in your thigh or lower leg
Femoral neuropathy may be caused by a variety of factors, including:
-
Certain drugs
-
Arthritis
-
Excessive alcohol consumption
-
Fibromyalgia is an example of a neurological illness.
-
Injuries
Treatment for femoral neuropathy varies depending on the etiology, but it often entails surgery, pain medication, or lifestyle modifications. Neuropathy isn’t always curable, but therapy may help to alleviate symptoms or keep them from worsening.
3. Plica Syndrome
Plica syndrome is caused by inflammation of the medial plica, which is a fold in the membrane that protects your knee. Plica syndrome may induce, in addition, to knee-buckling, the following symptoms:
-
Your knee is making clicking noises.
-
Discomfort on the inside of your knee
-
Tenderness and discomfort in your kneecap
The majority of instances of plica syndrome are caused by a knee injury or overuse of the knee. Physical therapy is frequently used to strengthen the muscles around your knee. A corticosteroid injection may also be required to decrease inflammation. In rare situations, your doctor may advise you to have surgery to remove or alter your plica.
4. Arthritis
Arthritis is an inflammation of the joints, most often affecting the knees. Knee buckling is a typical sign of both osteoarthritis and rheumatoid arthritis, which is an inflammatory illness. While rheumatoid arthritis normally affects both knees, osteoarthritis may only affect one.
Both osteoarthritis and rheumatoid arthritis may result in the following symptoms:
While there is no treatment for arthritis, you may control your symptoms by doing the following:
-
Nonsteroidal anti-inflammatory medicines (NSAIDs) are examples of pharmaceuticals.
-
Injections of corticosteroids
-
Physiotherapy
-
Wearing a splint or other supportive equipment, such as a knee brace
5. Multiple Sclerosis (MS)
Knee buckling is a symptom reported by some patients with multiple sclerosis (MS). MS is a disease in which your immune system attacks the protective coating of your nerves.
While there hasn’t been much study on the link between knee buckling and multiple sclerosis, weakness, and numbness in your legs are frequent symptoms of MS, which may cause your knee to buckle.
MS may produce a wide range of symptoms that vary from person to person, however, the following are some of the more prevalent ones:
Although there is no treatment for MS, corticosteroid injections may help lessen nerve irritation in your legs. Taking muscle relaxants might also assist if you suffer leg stiffness or spasms regularly.
Knee buckling regularly might be an indication of an underlying injury or ailment, so see your doctor. Meanwhile, attempt to rest your knee and use a hot or cold compress. You may either use a cane or wear a knee brace to lessen your chance of falling when your knees collapse.
Summary
When one or both of your knees collapse, this is referred to as knee buckling. In the past three months, 11.8 percent of individuals aged 36–94 had at least one episode of knee-buckling.
Physical Rehabilitation and Exercises
Certain exercises may assist to strengthen the leg muscles and enhance knee stability, hence preventing or reducing knee buckling.
-
A doctor or physical therapist may create an exercise regimen to address a person’s concerns about knee buckling. Typically, this will center on:
-
Strengthening the muscles that support the kneecap and maintaining it in a good position
-
Increasing upper and lower limb range of motion
-
Lowering stiffness
-
Enhancing adaptability
A normal knee rehab regimen will last 4–6 weeks. However, it is normally preferable to continue practicing these exercises for as long as possible to keep the knees healthy.
Stretching and strengthening activities include:
-
The quadriceps – the front leg muscles
-
The calves — the back muscles of the lower legs
-
The gluteal muscles – the buttock muscles
Following a knee rehabilitation program will assist a person in the following ways:
-
Enhancing their leg bending and straightening abilities
-
Increasing the amount of weight their legs can bear
-
Strengthening their inner and outer thighs and increasing their range of motion
It is critical to begin these workouts slowly and gradually. Before progressing to more difficult workouts, people must progressively increase their leg and knee strength and flexibility.
However, to achieve progress, individuals must push themselves a bit at home and in physical therapy sessions. It might be difficult to strike the perfect balance, but a skilled therapist can assist in ensuring that the degree of exercise is appropriate.
People who have knee buckling may need to change their activity routine. A person with arthritis, for example, may need to move from high-impact sports like running or tennis to lower-impact ones like swimming or cycling.
Cycling may also aid to strengthen upper-leg strength, which will contribute to greater knee stability.

When should you get Medical Attention for Knee Buckling?
Knee buckling may be a symptom of a more serious knee injury or illness. People who have knee instability are also more prone to fall and injure themselves.
Making an appointment with your doctor is the safest approach for dealing with knee buckling. Your doctor can assess the severity of any injury or sickness and identify any potentially significant issues.
Knee buckling Increases the Danger of Falling.
According to research published online on Feb. 8, 2016, by Arthritis Care & Research, knee-buckling in older persons may increase the risk of falling. Buckling, sometimes known as the knee “giving way,” is a sign of knee instability.
It often affects the elderly, particularly those suffering from knee discomfort or osteoarthritis. It might also be caused by leg muscle weakness or issues with balance.
When your knee buckles, you may lose your balance and fall, increasing your chances of damage and perhaps fractures. Recurring instances might also impair your ability to climb stairs.
Researchers looked at 1,842 people, 40% of whom were males, who were at high risk of knee osteoarthritis. After five years, 16.8 percent reported recurrent knee buckling, and those persons were 1.6 to 2.5 times more likely to suffer repeated falls, fear of falling, and low confidence in their ability to balance during the following two years.
According to the main researcher Dr. Michael Nevitt, a professor of epidemiology and biostatistics at the University of California, San Francisco, strengthening the quadriceps muscles (front of the thighs) may aid enhance knee stability and prevent buckling.
Knee buckling Without Causing Discomfort
Patients who have abrupt weakness in their legs are exhibiting a presenting symptom that needs immediate care. The term sudden weakness’ does not only relate to weakness in specific places that might continue for a few seconds, hours, or days.
Whereas in most situations when weakness has been persistent for weeks and has been overlooked by the patient, who suddenly appears with apparent sudden weakness
A basic problem in the knee, such as a tough muscle or an unanticipated piece in the protective tissues that maintain the knee moving flatly, is most frequently the source of sudden knee instability or weakness.
Summary
To address a person’s worries about knee-buckling, a doctor or physical therapist may devise an exercise routine. The therapy will be determined by the cause of the knee-buckling.
What exactly is a Knee Brace?
A knee brace is one method for relieving the pain of knee osteoarthritis. A brace may help relieve the discomfort by shifting your weight away from the most injured part of your knee. Wearing a brace may increase your mobility and allow you to walk further and more comfortably.
Knee arthritis braces come in a variety of styles. An unloader brace distributes weight away from the afflicted area of the knee.
The Dangers of Wearing a Knee Brace
Wearing a knee brace may provide the following risks:
Wearing the Brace Causes Discomfort
At first, a knee brace may feel heavy, thick, and heated. It may slide if it is not properly checked.
Itching or Swelling of the Skin
If your knee brace does not fit properly, the skin beneath the brace may become red and inflamed. Some individuals have swelling surrounding the combined as well.
No Gain
There have been few studies on knee braces for persons with osteoarthritis, and the outcomes have been mixed. Some folks perceive no advantage. Others have reported reduced pain and greater function.
Stiffness

Weight reduction and exercise, especially thigh-strengthening activities, are regarded as the best first-line therapies for knee osteoarthritis.
Summary
Wearing a brace may cause the user to perceive the braced knee as injured and favor the other knee, which may contribute to stiffness.
What Exactly is a “Trick Knee?”
In medical terminology, a trick knee, as it is often known, is known as a luxating patella. The patella is the kneecap, one of three bones that comprise the knee.
The patella, often known as the kneecap, is located in front of the knee. During leg movement, the patella slides up and down in the trochlear groove on the front of the femur. Tendons and ligaments hold the patella in place.
A luxation or subluxation is a condition in which the afflicted body moves unnaturally out of position. A dislocation is a full luxation or subluxation. A luxating patella is thus a kneecap that slides too far out of the trochlea.
The patellar subluxation or dislocation causes the patella to move to the outside of the knee during bending or pivoting actions. A “trick knee,” or a knee that unexpectedly gives way or collapses, may occur while participating in sports or during routine everyday activity.
One of the most common reasons for a trick knee is an unstable or subluxation kneecap. Other situations of knee instability, such as anterior cruciate ligament (ACL) deficit, may also induce knee giving way and instability; these knees are often known as “trick knees.”
Dr. Riley J. Williams, an orthopedic knee specialist who serves Manhattan, Brooklyn, New York City, NY, and the surrounding regions, has considerable expertise in treating luxating patellas, ACL injuries, and other knee buckling or trick knee concerns.
How Is A Trick Knee, Also Known As A Luxating Patella, Diagnosed?
Dr. Williams will examine the affected knee by bending and straightening the leg and feeling for the location of the kneecap. He will look for patellar instability as well as anterior knee instability caused by ACL rupture.
He will also request an x-ray to see how the patella fits into the trochlear groove. An MRI may be necessary to evaluate the patellar stabilizing ligaments (medial patellofemoral ligament) and the ACL.
An MRI may reveal soft tissue damage, such as tendons and ligaments, which may contribute to the instability of a trick knee. Cartilage injuries may arise as a result of these conditions; MRI scans can aid in the diagnosis of such injuries.
How Long Does It Take To Recover After Trick Knee Surgery?
Returning to regular daily activities may take as little as 2-3 months. It may take 6-9 months following surgery to return to sports. Physical therapy will aid in the correct healing and functional rehabilitation of the patient. Patients who undergo surgery are substantially less likely to have a reoccurring trick knee.
Before proceeding with any surgical surgery, the real cause of trick knee must be carefully diagnosed. Patients should seek the advice of Dr. Riley J. Williams, who has considerable experience treating trick knees, luxating patella, patella instability, and ACL injuries.
Summary
Knee buckling maybe a little inconvenience or a significant health risk. Depending on the cause, you may need physical therapy or surgery. Work with your doctor to determine what’s causing your knees to buckle, and take additional care while going up and downstairs.
Frequently Asked Questions
