Pain In Side Of Knee

Proximal Tibiofibular Joint Dislocation

Proximal tibiofibular joint dislocation is one of the most unusual causes of lateral knee pain. It affects the joint between the top of the shin bone and the fibular, the small, thin bone that runs down the outer side of the shin, just below the knee joint on the outer side.

It takes a large force to dislocate the joint, e.g. a car accident, but it can also partially dislocate usually due to a fall when the foot is plantarflexed , which often also damages the tibiofibular ligament.

Symptoms usually include outer knee pain, instability especially during deep squats and sometimes an obvious deformity at the side of the knee. There may also be associated damage to the peroneal nerve leading to pins and needles or numbness around the outer knee.

Anterior Knee Pain: The Basics

Pain in the front of the knee or anterior knee pain can affect people in all age groups. Approximately 25% of people will suffer from pain in the front of their knees at some time in their lives. I have seen teenagers who can longer participate in sports, and I have 70 years olds who can no longer walk downstairs without fear of their knee giving way. Why is our kneecap or patella so prone to bothering us like this?

The cause of anterior knee pain might vary based on your age, level of activity, and your chosen sports. We can see people who are inactive and suffer from pain in the front of the knee, and we can also see people who are highly trained and disciplined who are suffering from pain around the kneecap. The majority of people who have pain in the front of their knee do not recall any injury.

In the majority of cases of anterior knee pain, we do not find anything significant wrong with your X-rays or MRI scans. It seems that the pain in the front of the knee is often due to imbalances, weakness patterns, movement patterns, and complex issues that can take a while to figure out. Yes, some of you might have a cartilage defect or some early arthritis in the front of your knee but believe it or not, the majority of you will have pretty normal-appearing imaging studies. That has led to a significant change in our approach to anterior knee pain over the years.

Anterior knee pain is particularly common in young women and many runners.

When Should You See A Doctor

If you hear a distinct pop while exercising, or experience pain, swelling, or locking of the knee, you should see your doctor. They will ask about your symptoms and they may recommend imaging studies. This often includes a magnetic resonance imaging scan. Your doctor can often identify a bucket handle tear because it has a distinct double PCL sign, where the posterior cruciate ligament looks doubled because of the meniscus injury.

Is Anything Strange Happening

Or really, Is anything strange happening beyond your knee pain?

For example, can you still flex your knee all the way? Most people get frightened when their knee locks and cant straighten anymore. Often the culprit is called Bakers cyst, a fluid-filled sac behind the knee caused by inflammation.

A also triggers concern for many people. Nobody wants to hear a click with every step. Sometimes, its harmless, but if that clicking comes with pain, you might have a mechanical problem such as a torn meniscus, Dr. Burg says.

These are just a few examples among many. The knee is a complicated andcritical part of your everyday life. So when you have pain that comes withserious symptoms or lasts for more than a week or two, seek the right diagnosisby getting a physical exam and any necessary imaging that comes with it.

When To See A Doctor

If you are experiencing chronic pain or pain more associated with serious injury, see your doctor promptly. Not addressing your pain properly can lead to increased pain, joint damage, and disability. Depending on the cause of your knee pain, your doctor may suggest the following treatments:

• Medications: Your doctor may prescribe medications to help relieve pain in the back of the knee and swelling and treat underlying conditions like arthritis.
• Physical therapy: Your doctor may prescribe stretching exercises or a physical therapy/rehabilitation program to help you restore range of motion, strength and stability to your knee.
• Injections: In some situations, your doctor may suggest injecting medications and other substances directly into the knee joint in order to reduce inflammation, lubricate the knee and promote healing.
• Surgery: If conservative measures do not provide relief, your doctor may recommend surgical options.

What Is The Long

For minor injuries, the ligament may heal without any issue. However, its important to note that if the ligament got severely stretched, it may never regain its prior stability. This means that its more likely that the knee will be somewhat unstable and you could easily injure it again. The joint could become swollen and sore simply from physical activity or minor injury.

For those with a major injury who dont have surgery, the joint will most likely remain unstable and easily injured. You may not be able to do physical activities that require repetitive use of the knee, including running, climbing, or biking. Pain could result from minor activities like walking or standing for extended periods. You may have to wear a brace to protect the joint during physical activity.

For those who have surgery, the outlook will depend on the severity of the original injury and the surgical procedure. Generally, youll have improved mobility and stability after the joint completely heals. You may have to wear a brace or limit physical activities in the future to help prevent reinjuring the knee.

In knee injuries involving more than just the LCL, treatment and outlook may be different, as those injuries could be more severe.

Common Accompanying Symptoms Of More Serious Injury Are

Symptoms associated with more serious injuries include:

• Inability to bear weight on the knee
• Inability to fully straighten or flex the knee
• Fever: In addition to redness, pain, and swelling
• Obvious deformities in the knee or leg

Being able to differentiate these symptoms associated with pain in the back of the knee is important for preventing future injury and getting appropriate care.

Common Peroneal Nerve Injury

This nerve passes from the back of the lower thigh and crosses the lateral knee before supplying the lower leg muscles.

Similar to LCL injury, common peroneal nerve damage can occur from a blow to the inside of the knee, stretching the knee outwards. This injury can pull or tear the nerve.

Generally, symptoms include pain, numbness, and tingling of the lower legs outer part and the foots top.

What Does A Knee Injury Feel Like

Obviously, it hurts! But the type of pain and where you feel it can vary, depending on what the problem is. You may have:

• Pain, usually when you bend or straighten the knee
• Trouble putting weight on the knee
• Problems moving your knee
• Knee buckling or âlockingâ

If you have these symptoms, see your doctor. They will check your knee. You may also need X-rays or an MRI to see more detail of the joint.

Can Dehydration Cause Pain In The Back Of The Knee

In general, dehydration does not cause pain in the back of the knee. However, if you are dehydrated, you may experience cramping of your muscles. This is due to electrolyte imbalances leading to muscle irritation. This can lead to pain in the back of your leg if those muscles cramp. Most commonly, dehydration leads to exhaustion, thirst, muscle cramps, and dizziness.

Brief Anatomy Of The Knee

The knee is a vulnerable joint that bears a great deal of stress from everyday activities, such as lifting and kneeling, and from high-impact activities, such as jogging and aerobics.

The knee is formed by the following parts:

• Tibia. This is the shin bone or larger bone of the lower leg.

• Femur. This is the thighbone or upper leg bone.

• Patella. This is the kneecap.

Each bone end is covered with a layer of cartilage that absorbs shock and protects the knee. Basically, the knee is 2 long leg bones held together by muscles, ligaments, and tendons.

There are 2 groups of muscles involved in the knee, including the quadriceps muscles , which straighten the legs, and the hamstring muscles , which bend the leg at the knee.

Tendons are tough cords of tissue that connect muscles to bones. Ligaments are elastic bands of tissue that connect bone to bone. Some ligaments on the knee provide stability and protection of the joints, while other ligaments limit forward and backward movement of the tibia .

What Are The Benefits And Drawbacks Of A Custom

If youll be wearing a brace longer term , you may wish to consider a custom-fit brace. Your doctor will write a prescription for a brace and refer you to an orthotist. These medical specialists will take many measurements of your joints, movement patterns, and more to build a custom-fit brace.

A custom-fit brace is ideally the most comfortable and effective brace you can wear because its made exactly for you. However, they can be very expensive, sometimes costing around $1,500. Some insurance policies may pay for all or a portion of the cost. Also, this type of brace can take time to create. Many people wear a temporary brace until their custom one is completed.

What Causes Pain On The Inside Of The Knee

MCL Injury – The most common cause of inside knee pain is an injury to the medial collateral ligament . The MCL is the ligament runs up the inside of the knee joint and it helps stabilize the inside of the knee. MCL injuries typically occur when impact happens on the outside of the knee, which overstretches or tears the inside ligament.

Meniscus Injury – The meniscus is the piece of cartilage that cushions the knee joint as we walk. Depending on where on the meniscus an injury has occurred, a patient may experience inner knee pain.

Other Causes of Inside Knee Pain – Weakness of the muscles around the knee or arthritis may also cause pain on the inside of the knee. There may also be other causes for inside knee pain, but the ones listed here are the most common.

Knee Pain On The Outside Of The Knee

Your knee is a complex part of your body. Various ligaments and bones, different types of cartilage, and the iliotibial band are located in and around your knee.

Video of the Day

A number of problems with these structures can lead to pain on the outside of your knee. These problems are often the result of repeatedly bending your knee during sports or during years and years of everyday activities. Trauma to the knee can also lead to outside knee pain. Treatment depends on the underlying cause.

What Are The Limitations Of Using A Brace For Treatment

Not all people with OA benefit from a brace. A braces effectiveness often depends on where OA has caused areas of instability and damage. For example, if you have damage to the medial compartment of your knee, a brace can help because it places more support on your outer knee. If you have a tear or injury to your anterior collateral ligament, youll likely needs surgery to stabilize your knee.

According to a , braces have limited effectiveness because people wouldnt wear them. The reasons they stopped wearing the brace included:

Discomfort: Its possible the added weight could feel bulky and heavy.

Skin breakdown: Adjusting to a brace can result in chafing of the skin. An improperly fitting brace can also cause redness and irritation.

Swelling: While braces can reduce swelling, some people may experience swelling as a side effect of wearing a brace.

In addition to these considerations, knee braces may not be as effective as other methods of relieving arthritis pain. This can include weight loss to reduce pressure on joints and exercise to reduce stiffness.

Patellar Tendonitis And Tear

Patellar tendonitis is inflammation of the patellar tendon. That±s a large tendon connecting your kneecap to the top of your tibia.

Patellar tendonitis is most common in athletes who do a lot of running and jumping. Its often described as a constant dull pain that becomes sharp when youre active.

In some cases, a weak patellar tendon can tear. A patellar tendon tear causes:

• Swelling over the knee
• A tearing or popping sensation

If its a bad tear, you might notice an indentation at the bottom of your kneecap. The knee may give out when you walk.

When Will My Knee Feel Better

The recovery time depends on your injury. Also, some people naturally heal faster than others.

While you get better, ask your doctor if you can do an activity that wonât aggravate your knee pain. For instance, runners could try swimming or other types of lower-impact cardio.

Whatever you do, donât rush things. Donât try to return to your regular level of physical activity until you notice these signs:

• You feel no pain in your knee when you bend or straighten it.
• You feel no pain in your knee when you walk, jog, sprint, or jump.
• Your injured knee feels as strong as the other knee.

Symptoms Of Outer Knee Pain

The symptoms of outer knee pain will vary depending on the type of injury you have. Outer knee pain may feel dull and your knee may ache, or the pain can be sharp and limited to one area. You may have swelling from fluid that collects, or your knee may click or lock .

If you have iliotibial band syndrome, you may have pain all over the outside of your knee or the pain may be sharp and in one area. If your injury is mild, you might notice the pain come on after a certain time or distance when youre running, for example. And it may get better when you stop. If your injury is more severe, it might be painful to walk or even sit with your knee bent.

If you have a lateral collateral ligament injury, the outside of your knee will be painful. This ligament helps to keep your knee stable, so you may feel as if your knee is going to give way. You may have swelling around your knee, or pins and needles in your foot. You might find the pain is worse when you walk or run on uneven ground.

Symptoms of a torn meniscal cartilage include pain and your knee may also feel stiff, and lock or catch. There may be some swelling that may gradually get worse and you may find it difficult to fully straighten your leg. Pain can come and go, as can the swelling.

Pain from an anterior cruciate ligament injury will be sudden and you may hear a pop. Your knee is likely to swell from internal bleeding and may feel as if its going to give way.

Pain At The Back Of The Knee

• A sharp stabbing pain at the back of the knee can commonly be due to hamstring tendonitis, caused by inflammation of the tendons connecting the hamstring to the knee. A common cause is overuse, and the pain becomes more apparent with continued use.
• A swelling and tightness behind the knee might be due to inflammation of the popliteal bursa . This is often due to there being another mechanical abnormality within the knee producing excess fluid.
• Pain at the back of the knee may also be due to a tear in the posterior part of the meniscus.

How Are Knee Problems Diagnosed

In addition to a complete medical history and physical exam, other tests for knee problems may include:

• X-ray. This test uses invisible electromagnetic energy beams to make images of internal tissues, bones, and organs onto film.

• Magnetic resonance imaging . This test uses large magnets, radiofrequencies, and a computer to make detailed images of organs and structures within the body can often determine damage or disease in a surrounding ligament or muscle.

• Computed tomography scan . This test uses X-rays and computer technology to make horizontal, or axial, images of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general X-rays.

• Arthroscopy. A minimally-invasive diagnostic and treatment procedure used for conditions of a joint. This procedure uses a small, lighted, optic tube , which is inserted into the joint through a small incision in the joint. Images of the inside of the joint are projected onto a screen used to evaluate any degenerative or arthritic changes in the joint to detect bone diseases and tumors to determine the cause of bone pain and inflammation.

• Radionuclide bone scan. A nuclear imaging technique that uses a very small amount of radioactive material, which is injected into the patient’s bloodstream to be detected by a scanner. This test shows blood flow to the bone and cell activity within the bone.
