Pes Anserine Bursitis
Bursitis is a very painful condition in which a bursa sac inside the knee becomes irritated and inflamed. A bursa is a sac of synovial fluid, rich in protein and collagen. These fluid-filled sacs are located in areas where 2 surfaces in your body, most often where a bone and tendon or a bone and muscle, rub together during movement. Bursae play an important role in leading a healthy, active life as they allow your joints to move smoothly and painlessly.
With too much pressure or friction on a bursa, excess fluid can build up in the sac and/or the the lining of the sac can thicken, causing inflammation. When a bursa becomes inflamed, moving your knee becomes very painful and movement can be difficult. Any actions that put pressure on the inflamed bursa can increase irritation and cause further inflammation and pain.
Specifically, the pes anserinus is the area where the tendons of 3 hamstring muscles (sartorius, gracilis, and semitendinosus) come together. The three tendons merge together on the inside surface of the shinbone. These three muscles are the dominant knee flexors that function to allow movement of the leg towards the body and control rotation of the tibia, protecting the knee against rotary stress. The pes anserine bursa lies beneath these tendons close to the shinbone, providing cushioning between the tendons and the tibia. The term, pes anserinus means "goose's foot" in Latin - owing to the webbed-foot pattern the three tendons make when they meet.
Inflammation of the pes anserine bursae or tendons usually develops due to overuse, trauma, or degradation. The most common cause of pes anserine bursitis is hamstring tightness due to a lack of warming up and stretching properly before activity, particularly long distance running or excessive climbing.
Pes Anserine Bursitis Causes
- Poor technique or improper warm-up in sports
- Repetitive knee bending
- Carrying excess load due to obesity overstressing the knee joint
- Arthritis or osteoarthritis
- Biomechanical issues, such as foot rolling, out-turned knees, or limping
- A medial meniscus tear
- Overuse or traumatic injury during athletics
Pes Anserine Bursitis Symptoms
Pain, Tenderness and Swelling
If you suffer from bursitis in your pes anserine bursa you will feel pain or tenderness over your tibia, approximately 2-3 inches below the patella (kneecap). The pain often radiates to the back and inside of the thigh.
Bursitis pain becomes worse during exercise or when you are climbing stairs, but can also increase by simply bending and straightening your knee. Pain usually starts gradually and develops over a few days or even months.
Swelling is usually evident over and around the bursa that is inflamed. This swelling may appear immediately following trauma, over a couple of hours, or up to 7-10 days after the incident.
You may also notice warmth and visible redness on your skin in the area as inflammation in the bursa and along the tendons becomes more severe.
Patients suffering from knee bursitis may also have interrupted sleep patterns. Simply bending your knee or rolling over during sleep can cause pressure on the inflamed bursa, increasing your pain. The pain can range from mild to very sharp depending on the amount of inflammation in your knee. Many knee bursitis sufferers recommend placing a pillow between your knees/thighs while you sleep to reduce pain throughout the night.
Limited Range of Motion and Weakness
When you have bursitis in your knee, the pain is often limiting as you stop performing motions that make the pain worse. If bursitis is left untreated the inflammation can increase, causing more pain, limiting movement even more and eventually weakness in the leg muscles and tendons can set in. As you lose strength in your quadriceps, your legs may begin to give out during daily activities.
It is important to treat bursitis in the early stages to reduce the symptoms, minimize damage and maintain motion and strength in your knee. Eliminate any squatting, repetitive knee bending, crossing your legs, kneeling or any other activities that add pressure on your bursa. By treating your knee bursitis in the early stages with cold compression therapy and Blood Flow Stimulation Therapy™, you are more likely to prevent long-term damage and chronic conditions from setting in.
Treating Knee Bursitis
Relieving the symptoms of bursitis initially focuses on keeping the pressure off the bursa. If your bursitis is caused by an infection (septic bursitis), the doctor will probably drain the bursa sac with a needle and perscribe antibiotics to treat the infection. For non-infectious bursitis, the preliminary treatment starts with non-operative options such as elevation, rest and cold compression therapy.
The most important factor in healing bursitis is resting your knee. This can be difficult when you have to carry on with daily activities, but resting whenever you can is recommended. During your recovery you will probably have to modify or avoid the activities that stress your bursa until your pain and inflammation settle.
Treatments should involve decreasing swelling, relieving stress on the knee, treating scar tissue, and then restoring strength and movement in your leg and knee. Blood flow stimulation therapy (BFST®) is recommended once inflammation has been calmed to heal the bursa and surrounding tissue faster and reduce the risk of bursitis returning.
Freezie Wrap® Cold Compression Therapy
To decrease inflammation and relieve the pain of pes anserine bursitis doctor's recommend cold therapy.
Applying cold to your inflamed bursa will help decrease the swelling and redness around it. Cold therapy will also help to numb the pain in your knee and help to control the inflammation. In addition, the deep cooling effect provided by the Knee Freezie Wrap® reduces tissue damage.
The Knee Freezie Wrap® uses a supercharged cooling gel pack, that chills in the fridge, not in the freezer like ice or other freezer packs, giving you deep cold therapy without the risk of 'cold burns' or cryoburn.
Cooling your inflamed pes anserine bursa as needed throughout the day will reduce pain and tissue damage. The Knee Freezie Wrap® can be used to apply cold in a safe, convenient and effective way - and the gel pack is reusable. The gel pack sits gently over the inflamed bursa to reduce swelling and redness.
The wrap is soft and adjustable so it fits your body properly, without irritating the bursa, and allows you to adjust the compression. This is important when treating an inflamed bursa because too much pressure can cause you further pain. You control how much pressure the bursa receives so you can benefit from the compression to hold the cold where you need it, without increasing your pain.
Applying cold to your tender bursa is the first step in treating your bursitis. Once pain and swelling has diminished, use the Inferno Wrap® (BFST®) wrap to accelerate the healing of your injured bursa.

Inferno Wrap® Blood Flow Stimulation Therapy
Once the inflammation of your bursitis has been reduced with cold therapy treatments it is time to improve blood flow and improve the elasticity of your surrounding soft tissue. Your body needs a fresh supply of blood to improve the health of your tissue and get your knee bursae and tendons back to normal.
Unfortunately, when you are suffering from bursitis it can be painful to even walk or lift your leg. When you limit movement in your knee joint the blood flow is reduced, starving your tissue of the necessary oxygen and nutrients.
The trick is to find a way to increase blood flow without causing pain and/or further inflaming the bursae. This is where blood flow stimulation therapy, or BFST®, becomes a powerful tool.
BFST® compliments your body's natural healing process by promoting blood flow while you give your knee the rest it needs.
The Knee Inferno Wrap® uses a patented process to generate the same energy that is part of the sun's spectrum of light, the same energy that is necessary to all living things for optimum health. The energy emitted from the Energy Pad stimulates blood flow to your knee, more than your body would ever be able to generate on it's own, giving your body the boost it needs to continue the reconditioning process. The healing energy reaches deep into your knee bursa and tendons to speed tissue repair, whisk away the toxins and dead cells, and rejuvenate your tissues for improved elasticity.

NSAIDs, non-steroidal anti-inflammatory drugs, can be used if required to help manage your pain. However, these aren't recommended for long term use, as they can cause gastrointestinal difficulties and increase the risk of cardiovascular disease. The use of cold therapy, BFST® and the Knee-Flex® Passive Knee Stretch Device in conjunction with NSAIDs can greatly improve the effect of this medication and can help to heal quicker.
Your doctor may aspirate your inflamed bursa. This involves removing the extra fluid that has built up with a needle. Sometimes, the fluid will be tested at a laboratory to rule out infection.
If your bursitis does not get better with conservative treatments, the bursa may be surgically removed. Usually this is done by arthroscopic surgery, which is a surgical procedure where tiny incisions are made and a pencil-sized camera is inserted into the knee. A small shaver is inserted into another incision, and is used to remove the swollen bursa all together. The surgeon will then look for any damage to the knee and make repairs if necessary. This is also done to remove any bone spurs that are causing irritation.
Recovery time for the surgery will depend on a number of different factors including your healing ability, diet, rest and how many procedures were done in your surgery.
Post-op recovery time can be reduced with the use of cold compression, and blood flow stimulation therapy following surgery. Cold compression is recommend by doctors following surgery to treat your pain in a natural, non-addictive way and to reduce swelling. Once the incision has healed, speak with your doctor about the use of the Freezie Wrap® cold compression wrap and Inferno Wrap® BFST® treatments. BFST® encourages more oxygen and nutrients to flow to the area to speed healing and improve the elasticity and strength of the soft tissue in your knee while minimizing and even reducing scar tissue. Incorporate use of the Freezie Wrap® once your incisions have healed to minimize the pain and swelling from the surgery. Using the Inferno Wrap® once post surgery swelling has reduced will treat the scar tissue that forms from your surgery and basically give you a great chance of full recovery while reducing the chance of re-injury. Treating scar tissue is the most important step following surgery, especially in a joint, to improve the range of motion in your knee. Leaving the scar tissue untreated can lead to stiffness, chronic knee pain, re-injury, osteoarthritis or other knee conditions.
Physical therapy is a beneficial way to restore atrophied muscles and improve strength and mobility after treating bursitis. The type of physical therapy and the duration will be dependent on the tissue damage and your symptoms. When you are treating or recovering from bursitis, it is important to ensure you do not perform any exercises that will further irritate the bursa.
Once your pain starts to diminish, a physiotherapist will set up an individualized strengthening and stretching exercise program for you to perform at home or in the gym. This will be based on your needs and abilities, and will help you return to performing your normal routines.
Individuals will often lift weights on their own, to try and build up their strength. However, in doing so, they can do more damage to the weak knee. It is extremely important to strengthen your muscles properly. A trained therapist will help to ensure your rehabilitation process is appropriate and effective. For best, long term results use BFST then the Knee-Flex® Passive Knee Stretch Device at home in conjuction with physical therapy.
During your recovery, you may have to modify and/or eliminate any activities that cause pain or discomfort in your knee joint until your pain and inflammation settle, and you gain more mobility and strength. The more diligent you are with your rehabilitation, the faster you will see successful results.
