How Is A Baker Cyst Treated
You likely wont need any treatment if you dont have any symptoms from your Baker cyst. Some Baker cysts go away without any treatment. If your cyst starts causing symptoms, you might need treatment at that time.
If you do have symptoms, you may be treated depending on the cause of your cyst. For example, you may need medicine for rheumatoid arthritis. Or you may need physical therapy for osteoarthritis.
Other treatments for a Baker cyst can include:
- Over-the-counter pain medicines
- Arthrocentesis to removes excess fluid from the joint space
- Steroid injection into the joint to reduce cyst size
- Surgery to remove the cyst
Most Baker cysts go away without surgery. Healthcare providers only rarely advise surgery. You might need surgery if your Baker cyst is causing you severe symptoms and no other treatments have worked. Your provider will check you carefully for other knee problems to treat before advising surgery. In many cases, a Baker cyst will come back after surgery. This is most often true when its caused by a problem that hasnt gone away.
Youre Dealing With An Injury
Whether you took a tumble during your workout or just walked smack into the coffee table, swelling is a normal reaction to injuriesincluding those around your knees. In fact, injuries are the most common reason for swollen knees that James Gladstone, MD, chief of sports medicine at The Mount Sinai Health System, sees in younger, healthy patients.
Injuries signal an inflammatory response in the body, which causes swelling, Dr. Gladstone explains. Immediately post-injury, blood flow to the injured area increases, delivering the rush of fluids, proteins, and white blood cells needed to start the healing process. As a result, the injured area becomes red and swollen.
Two common knee injuries: a torn ACL and a torn meniscus .
Treatments That Have Already Been Instituted
Many patients have undergone physiotherapy, steroid injection or previous arthroscopy. The success of previous therapies guides further management.
If a patient has not undergone physiotherapy this may be the first port of call particularly in anterior knee pain related to patellofemoral joint dysfunction. History of previous surgery, in particular total knee replacement or cruciate ligament reconstruction, associated with new onset of symptoms should warrant a referral to the orthopaedic surgeon.

Symptoms Of Pain Behind The Knee

Pain behind the knee is sometimes referred to as posterior knee pain. Your knee joint is made up of ligaments, tendons, cartilage, muscles, and bones.
According to Dr. Matthew Hoffman on WebMD, the knee is one of the most complex joints in the body. Tendons connect the thigh bone and shin bone to your leg muscles. These work together to provide stability and movement to your knee.1
For example, your hamstring is at the back of your thigh and helps to flex the knee. However, a pulled hamstring will cause pain in your thigh and at the back of your knee.
Dr. Jerry R. Balentine on MedicineNet says that damage to the ligaments and tendons in your knee can cause bones to rub together and result in inflammation, redness, and pain around the back of the knee or kneecap. This can make walking difficult, and instability in the knee joint could result in more pain and damage. In some cases, the pain can be so disabling and severe that it is impossible to put any weight on your leg.2

How Does A Meniscal Cyst Develop
Usually, a tear forms in the meniscal cartilage from degeneration or an acute injury. Fluid from the knee joint then leaks out of the tear forming a cyst. So, a meniscal cyst is not a true cyst but an outpouching of displaced knee fluid. Also, the cartilage tear can form a one-way valve preventing the fluid from going back into the knee. The fluid then collects as a cyst below knee cap.
Often, meniscal cysts form in people with a past history of a knee injury, cartilage damage, or contact or twisting sports. Also, the presence of arthritis predisposes to the formation of a cyst on side of knee.

A Secondary Baker’s Cyst
Sometimes a Baker’s cyst can develop if there is an underlying problem within the knee, such as arthritis or a tear in the meniscal cartilage that lines the inside of the knee joint. This type of Baker’s cyst is the most common. It is sometimes referred to as a secondary Baker’s cyst.
In a secondary Baker’s cyst, the underlying problem within the knee joint causes too much synovial fluid to be produced within the joint. As a result of this, the pressure inside the knee increases. This has the effect of stretching the joint capsule. The joint capsule bulges out into the back of the knee, forming the Baker’s cyst that is filled with synovial fluid.

What Causes Tightness Behind The Knee
Tightness behind the knee is often caused by tightness in the hamstring or calf muscles. The hamstring muscles run down the back of the thigh attaching behind the knee, and one of the calf muscles, gastrocnemius, starting from the back of the knee, travels down to the heel.
Tightness in these muscles is a common problem, particularly in men, and makes the back of the knee feel very tight. Simple knee stretches are the best way to treat the tightness and relieve back of knee pain.
Blood Clots Behind Knee
It is important to note that pain and swelling behind the knee may be associated with blood clots. Blood clots behind the knee are especially common for those on bed rest or prolonged laying down, recovering from surgery or who have experienced trauma to the knee. Age and weight may also be a factor in blood clots. If you are experiencing behind knee pain, see a doctor to diagnose your situation, especially as you may be experiencing a blood clot behind knee.

What Is A Baker Cyst
A Baker cyst is a fluid-filled sac that forms behind the knee. It’s also known as a popliteal cyst or popliteal synovial cyst.
The knee is a complex joint that has many parts. The lower end of the thighbone rotates on the upper end of the shinbone . The knee joint is filled with a special fluid that cushions the joint.
A Baker cyst forms when an injury or disease causes extra synovial fluid to leak into the extra space behind the knee.
Baker cysts are common in both adults and children. But theyre more common as a person gets older.
Clinical Findings Of A Lump On The Side Of Knee
Not all lumps on the side of the knee are obvious or painful. In cases where the lump is due to a meniscal cyst, the more common symptoms include pain with standing, swelling in the knee joint, and a lump or bump on the side of the knee that can change in size.
When examining the knee, we often find a lump close to the joint line. The lump is usually soft and may or may not be painful. Also, twisting or rotating the knee can cause pain.
Generally, we use an MRI to diagnose the cyst and the corresponding tear. However, an ultrasound can also confirm a meniscal cyst.
