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.
How Do You Know If You Have A Blood Clot Behind Your Knee
A blood clot in the veins of your lower leg is called a deep vein thrombosis or DVT. You may have a blood clot behind your knee if you have one-sided leg swelling, pain, warmth, and redness below the knee. Sometimes these clots can occur on both sides at once, but this is uncommon. Some blood clots in the legs, however, do not present with any symptoms. A DVT requires immediate treatment to reduce the risk of embolizing to the lungs.

You may need to make changes to your diet, especially if youre treating gout.
Meniscus Tears And Pain Behind Your Knee
Root tearsof the meniscus are prevalent. The root of a meniscus is where the meniscus attaches to the shin bone or tibia. Much like a tree roots into the ground, the meniscus has a firm, deep attachment to your bones as well.
Sadly, over the years, these attachment points or roots can weaken. A common story is that you bent down or knelt and felt a pop in the back of the knee. Later that day or two days later, your knee is swollen, and the pain is very severe. The root of the meniscus tore in this situation because it had degenerated from decades of activity.
The pain from root tears often subsides over the next few weeks to months. By the time you see a doctor, and they order an MRI, the pain is often starting to improve. This post below goes into far more detail about root tears as the cause of pain in the back of your knee.
The meniscus is a shock absorber. When the root of the meniscus tears, the meniscus no longer works as a shock absorber. Therefore, following a root tear, you may develop stress fractures or stress reactions. That is why the pain worsens a few days after you felt the pop.
On some occasions, we need to consider surgery to repair these root tears but this is not usually necessary.

You Cant Put Weight On Your Knee
If you cant bear weight on your knee, theres a good chance theres something serious going on.
The inability to put weight on your knee after a knee injury could be caused by a fracture, bone contusion, cartilage injury, or ligament tear.
After a minor injury like a twist or fall, you probably wont be able to immediately put weight on your leg.
Thats normal, but if you havent recovered within a few minutes or a few days, or it has turned into chronic knee pain, it could indicate something more serious.
You should also watch out for numbness after the injury.
Numbness could be the result of a pinched or damaged nerve and blood vessels.
This could be a symptom of an ACL or MCL tear, a kneecap dislocation, a fractured kneecap, or loose bone.
Osteoarthritis Of The Knee
The most common type of arthritis is osteoarthritis, which is a progressive wearing of the cartilage in the knee joint. It occurs more frequently in people age 50 and older.
After 50, the impact of osteoarthritis can worsen due to accumulated use and the wearing down of cartilage that occurs with age.
Osteoarthritis is often the result of bone rubbing on bone, and yes, thats as painful as it sounds. Osteoarthritis can also be caused by age, weight, genetics, previous injuries, infections, illness , and certain occupations, such as construction and manufacturing.

- tendinitis: pain in the front of the knee that is made worse when climbing, taking stairs, or walking up an incline
- bursitis: inflammation caused by repeated overuse or injury of the knee
- gout: arthritis caused by the buildup of uric acid
- Bakers cyst: a buildup of synovial fluid behind the knee
- rheumatoid arthritis : a chronic autoimmune inflammatory disorder that causes painful swelling and can eventually cause joint deformity and bone erosion
- dislocation: dislocation of the kneecap most often the result of trauma
- meniscus tear: a rupture in one or more of the cartilage in the knee
- torn ligament: tear in one of the four ligaments in the knee the most commonly injured ligament is the anterior cruciate ligament
- bone tumors: osteosarcoma , most commonly occurs in the knee
Factors that may make chronic knee pain worse:
- injuries to the structure of the knee can cause bleeding and swelling and can create a chronic problem over time if not treated properly

- Is the knee pain affecting one or both knees?
- Do you often feel your knees buckling?

- How would you explain the cause of your knee pain?
Self-diagnose with our free Buoy Assistant if you answer yes on any of these questions.
Your Knee Keeps Buckling
When you got hurt, did it feel like your knee gave way underneath you? Were not talking about a temporary sensation of weakness or some wobbliness, but more like your shin and thigh bone werent connecting or staying in place. A buckling knee could signal an ACL tear or a cruciate ligament injury.
It could start with a small pop or crack, or you could feel it after a strenuous exercise session or a soccer game.
Either way, your knee feels unstable or weak. Your knee may give out momentarily, which is scary because you might not trust yourself to walk safely when this happens. According to Dr. Howard Luks, an orthopedic surgeon, this could indicate a tear in the patella or the quadriceps tendon.
These tendons are on the front of your knees and offer a lot of support to keep you upright. If theyre not in top form, youre bound to feel weak in the knees , and you might not be able to walk at all. If this is the case, you could need surgery.
On the other hand, the weakness could be temporary, caused by wear and tear, improper footwear, or a strain. If youre a weekend warrior or youre over the age of 30 , you might experience this symptom on a regular basis.
However, if the weakness is recurring and happens every time you exercise, its possible you have a time bomb thats waiting to happen. When in doubt, seek advice from a physician.
If your knee buckles under you when you are walking, then it usually indicates instability, she says.

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 .

Your Knee Feels Unstable Or You Felt A Pop
Most ACL tears and patella dislocations occur from a twisting, non-contact injury. A typical story is that you were turning or twisting hard, and you felt a pop. As I mentioned earlier, most patella dislocations will reduce or go back into their usual place on their own. But if your patella remains dislocated the knee will look strange.
If you felt or heard a loud pop as you twisted or turned to avoid another player, then you may have torn your ACL. Other causes of popping include a patella or kneecap dislocation. If you felt or heard a loud pop in your knee, then there is a strong chance that you have a severe knee injury. Most ACL injuries and patella dislocations are non-contact injuries. A running back turning to head upfield. A striker moving laterally to avoid the defense. These are familiar stories when we see high school and college athletes who have torn their ACL.
This post dives further into the immediate management of suspected ACL injuries.
Is It Possible For Adults To Have Growing Pains
No one knows for certain what causes âgrowing pains.â They are defined as self-limited and recurrent pains in the extremities of children with no other explanation or clear musculoskeletal causes. These usually occur during sleep and may awaken the child. Some physicians believe they occur due to fatigue, overuse, and mild orthopedic abnormalities, but the cause is still unknown. No matter what causes growing pains, we know that adults do not have them â most growing pains occur between age 2 and 12. It is possible to have similar pains, however, due to very mild injuries or overuse of muscles.

Will Surgery Treat And Cure Knee Pain
Knee operations range from arthroscopic knee surgery to total knee replacement. Arthroscopic knee surgery is a very common surgical procedure that allows the physician look inside your knee through a few small holes and a fiberoptic camera. The surgeon can repair many of the injuries and remove small pieces of loose bones or cartilage. This is a common outpatient procedure.
Partial knee replacement: The surgeon replaces the damaged portions of the knee with plastic and metal parts. Because only part of the knee joint is replaced, this procedure has a shorter recovery then a total knee replacement.
Total knee replacement: In this procedure, the knee is replaced with an artificial joint.
For Ligament Cartilage And Joint Tears
Ligament, cartilage and joint tears in your knee will need to be addressed by your doctor.
After imaging diagnostics and a clinical assessment, your doctor will let you know if your treatment will include physical therapy and anti-inflammatory medication, or if youll need to undergo surgery to repair the injury.
Recovery from knee surgery can take some time. It may take anywhere from 6 months to a year to resume your normal activities.

Your Knee Is Unstable Or It Pops
If you have pain in your knee and it feels unstable, or you heard it pop, you may have an anterior cruciate ligament tear or a dislocated knee cap.
These injuries typically occur when you twist your knee.
These are often the non-contact knee injuries you see many athletes sustain.
Knee cap dislocations are more common than most people think.
Most of the time, a dislocated knee cap will go back into place, but if it remains dislocated, your knee will start looking strange.
Surgery to repair the patella ligaments usually isnt necessary for your first dislocation.
Anytime you hear a loud pop in your knee accompanied by pain, there is a strong chance your knee pain is serious and you should see a doctor for medical advice.
I Only Have Pain Behind My Knee When Walking Up Or Down The Stairs What Should I Do
The act of walking up and down stairs involves straightening the knee whilst it is bearing weight, and the the most common cause of pain in this case is chondromalacia patella. This condition is brought about by the cartilage on the underside of the kneecap deteriorating and softening. Some people can ignore the condition, but in the end it will probably need to be surgically addressed. It may be that a flap of cartilage has become unstable, in which case it can be treated by a chondroplasty, repairing the damaged cartilage using keyhole surgery.
