  • What’s Causing This Pain in the Back of My Knee?

Is this cause for concern?

The knee is your body’s biggest joint and one of its most injury-prone areas. It’s made up of bones that can crack or move out of joint, as well as cartilage, ligaments, and muscles that can strain or split.

Some knee damages finally heal on their own with rest and care. Others need surgery or other medical attacks. Sometimes the pain is a symptom of a chronic condition like arthritis that damages the knee gradually over time.

Here are some of the states that can create pain in the back of your knee, and what to await if you have one of them.

Leg cramps

Leg cramps

Pain is a tightening of a muscle. Muscles in the yearlings are several likely to cramp, but other leg tissues can cramp up, too including muscles in the rear of the thigh next to the knee.

You’re more likely to have leg cramps when you exercise or through pregnancy. Other possible reasons include:

  • nervure problems in your legs
  • dehydration
  • diseases, such as tetanus
  • toxins, like lead or mercury in the blood
  • liver disease

When you have a cramp, you’ll quickly feel your muscle liability or spasm. The pain serves anywhere from a few moments to 10 minutes. After the pain passes, the muscle may be sore for several hours. 

Jumper’s knee

A jumper’s knee is damage to the tendon — the cord that attaches your kneecap (patella) to your shinbone. It’s also called patellar tendonitis. It can occur when you jump or turn direction, such as when playing volleyball or basketball.

These changes can cause small cuts in the tendon. Finally, the tendon swells up and loses.

Jumper’s knee

The jumper’s knee starts pain below the kneecap. The pain gets worse over time. Other symptoms add:

  • weakness
  • stiffness
  • trouble turning and straightening your knee

Biceps femoris tendonitis (hamstring injury)The hamstring include a trio of muscles that run down the rear of your thigh:

  • semitendinosus muscle
  • semimembranosus muscle
  • biceps femoris muscle

These muscles enable you to bend your knee.

Injuring one of these muscles is called a strained hamstring or a hamstring strain. A hamstring strain occurs when the muscle is stretched too far. The muscle can simply split, which can take months to recover.

When you hurt your hamstring muscle, you’ll feel immediate pain. Injuries to the biceps femoris called biceps femoris tendinopathy create pain in the back of the knee.

Other symptoms add:

  • swelling
  • bruising
  • weakness in the back of your leg

This kind of injury is common in athletes who run fast in sports like soccer, basketball, tennis, or track. Stretching the muscles out before play can help limit this injury from happening.

Baker’s cyst

A Baker’s cyst is a fluid-filled sac that forms back the knee. The fluid inside the cyst is synovial fluid. Generally, this fluid acts as a lubricant for your knee joint. But if you have arthritis or a knee injury, your knee may give too much synovial fluid. The excess fluid can build up and form a cyst.

Symptoms add:

  • pain in and behind your knee
  • swelling behind your knee
  • stiffness and trouble flexing your knee

These symptoms can make you more serious when you’re active. If the cyst bursts, you’ll feel a sharp pain in your knee.

Baker’s cysts sometimes go away on their personal. To treat a large or painful cyst, you may want steroid injections, physical therapy, or to have the cyst drained. It’s necessary to find if an underlying issue is letting the cyst, such as arthritis. If so, taking care of these issues first may result in Baker’s cyst making up.

Gastrocnemius tendonitis (calf strain)

The gastrocnemius muscle and the soleus muscle make up your calf, which is the rear of your lower leg. These muscles help you turn your knee and point your toes.

Any sport that wants you to fast go from a standing posture to a run — like tennis or a squash — can strain or split the gastrocnemius muscle. You’ll know that you’ve strained this muscle by the immediate pain it starts in the back of your leg.

Other symptoms add:

  • pain and swelling in the calf
  • damaging in the calf
  • trouble standing on tiptoe

The pain should subside rely on the size of the damage. Resting, raising the leg, and icing the injured area will help it set faster.

calf strain
Meniscus tear

Meniscus tear

The meniscus is a wedge-shaped portion of cartilage that cushions and supports your knee joint. Each of your knees has two menisci — one on both sides of the knee.

Athletes sometimes tear the meniscus when they squat and twist the knee. As you get older, your meniscus weakens and degenerates and is more likely to split with any twisting movement.

When you spilled a meniscus, you might hear a “popping” sound. At first, the damage might not hurt. But after you walk on it for several days, the knee can become more painful.

Other signs of a meniscus tear are:

  • stiffness in the knee
  • swelling
  • weakness
  • locking or giving way of the knee

Rest, ice, and elevation of the modified knee can help ease the symptoms and allow it to cure faster. If the tear doesn’t grow on its own, you might want surgery to correct it.

Anterior cruciate ligament injury

The anterior cruciate ligament (ACL) is a band of tissue that works by the front of your knee joint. It connects your thighbone to your shinbone and helps support and give movement to your knee.

Most ACL injuries occur when you slow down, stop, or change direction quickly while working. You can also strain or spilled this ligament if you land a jump wrong, or you get a click in a contact sport like football.

You force to feel a “pop” when the injury occurs. Then, your knee will hurt and swell up. You strength have difficulty fully moving your knee and feel pain when you walk.

Rest and physical therapy can correct an ACL strain cure. If the ligament is torn, you’ll usually require surgery to fix it. Here’s what to demand during ACL repair.

Anterior cruciate ligament injury
Posterior cruciate ligament injury

Posterior cruciate ligament injury

The posterior cruciate ligament (PCL) is the ACL’s companion. It’s another band of tissue that connects your thighbone to your shinbone and helps your knee. But, the PCL isn’t as possible to become damaged as the ACL.

You can damage the PCL if you take a hard hit to the front of your knee, such as in a car accident. Sometimes damages happen from twisting the knee or missing a step by walking.

Stretching the ligament too far creates a strain. With sufficient pressure, the ligament can tear into two sections.

Along with pain, a PCL injury begins:

  • swelling of the knee
  • stiffness
  • trouble walking
  • weakness of the knee

Rest, ice, and elevation can help a PCL injury cure faster. You might want surgery if you’ve damaged more than one ligament in your knee, have symptoms of change, or also have cartilage damage.


Chondromalacia occurs when the cartilage inside a joint breaks down. Cartilage is a rubbery material that cushions bones so they don’t irritate against one another when you move.

Injury to the knee, or a regular wearing down from age, arthritis, or overuse, can make chondromalacia. The most basic site of cartilage breakdown is below the kneecap (patella). When the cartilage is gone, the knee bones scrape against each other and create pain.

The main symptom is a dull ache back your kneecap. The pain may get more serious when you rise stairs or after you’ve been lying for a while.


Other symptoms add:

  • difficulty moving your knee past a sure point
  • weakness or buckling of the knee
  • a cracking or crunching feeling when you turn and straighten your knee

Ice, over-the-counter pain relievers, and physical therapy can help with the pain. Once the cartilage is destroyed, chondromalacia won’t go away. Only surgery can fix the broken cartilage.


Arthritis is a degenerative disease in which the cartilage that cushions and helps the knee joint gradually fades away. There are a few types of arthritis that can hit the knees:

  • Osteoarthritis is the most normal type. It’s a regular breakdown of cartilage that happens as you age.
  • Rheumatoid arthritis is an autoimmune disease in which the immune system wrongly attacks the joints.
  • Lupus is a different autoimmune disease that creates inflammation in the knees and other joints.
  • Psoriatic arthritis begins with joint pain and broken pieces on the skin.

You can manage arthritis pain with exercise, medicines, and pain medicines. Rheumatoid arthritis and other inflammatory forms of the condition are treated with disease-modifying drugs that depress the immune system reply and bring down infection in the body.

Gastrocnemius tendonitis (calf strain)

Deep vein thrombosis

Deep vein thrombosis (DVT) is a blood clot that forms in a deep vein inside the leg. You’ll feel pain in the leg, particularly when you stand up. Here’s how to tell if you have a blood clot.

Other symptoms add:

  • swelling of the leg
  • warmth in the area
  • red skin

It’s necessary to make DVT treated as promptly as possible. A clot can break and travel to the lungs. When a clot gets stuck in an artery of the lungs it’s called pulmonary embolism (PE). PE can be life-threatening.
