All YOU simply need is the right treatment.
King Brand Healthcare Products is the manufacturer of FDA-registered Class II medical devices for the treatment of soft tissue injuries. This guide covers what a Bakers cyst is, why it happens, and how to treat it correctly.
A Baker's cyst (popliteal cyst) is a fluid-filled swelling behind the knee. It forms when excess synovial fluid accumulates and bulges backward. The key: the cyst itself is not the primary problem. It is a symptom of an underlying knee condition -- usually a meniscus tear, osteoarthritis, or ligament injury -- that is producing excess fluid.
This is why King Brand says "you have two things to treat, not one." Treating the cyst (draining it) without treating the underlying cause is temporary. Effective treatment must address both the cyst and the underlying knee injury. ColdCure reduces the swelling; BFST heals the underlying tissue.
The most common symptoms:
If the cyst ruptures, fluid may flow down the calf. Consult a physician immediately to rule out DVT.
See Baker's Cyst Information for more detail.
The King Brand treatment protocol for a Baker's cyst uses three FDA-registered medical devices working together, each addressing a different part of the recovery problem:
The order matters. Cold first, because treating an inflamed injury with anything else is premature. Support throughout, because every re-injury resets the healing clock. Blood flow stimulation once the acute phase is controlled, because that is what actually heals the joint.
For the full protocol details, see Baker's Cyst Treatment.
BFST® + ColdCure® + KB Tape™
BFST® for Rapid HealingColdCure® for Pain & SwellingKB Tape™ to Prevent Re-Injury
Combination Therapy means using ColdCure®, KB Support Tape™ and BFST® in combination by alternating treatments. Combination Therapy is much more effective than using just one product or the other. This is because you're getting the pain and swelling relief of ColdCure®, the healing benefits of BFST®, and the protection and re-injury prevention of KB Support Tape™, resulting in the absolute best treatment for your Bakers Cyst.
ColdCure is a registered Class II medical device that delivers cold compression therapy for pain, swelling, and inflammation associated with soft tissue injuries.
Cold and compression applied to an injury that is swollen, inflamed, or painful is extremely effective. ColdCure treatments are beneficial following injury until the pain, swelling, and inflammation are gone, and any time you experience symptomatic flare-ups.
Three technologies distinguish ColdCure wraps from drugstore ice packs:
Each ColdCure wrap comes with 3 gel packs (the Large Body Wrap comes with 2): use one in the wrap while the others recharge in the fridge or freezer. Switch to a freshly charged pack when the cold diminishes, typically after 20 minutes.
KB Support Tape is a registered Class I medical device with two functions: ongoing compression to control swelling, and support to protect against re-injury.
The support function is the important one for a Baker's cyst recovery. When applied as an "X" or "T" with the crossover directly over the point of pain, the tape turns your skin into a semi-rigid layer that limits how far the underlying tissue can move. King Brand calls this "armor for your injury."
The mechanism: re-injury happens when you stress the joint past its current limit. Tape does not remove the load, but it reduces how far "too far" is. Say your joint can handle a 20-pound load but not 25. If tape reduces strain by 3 or 4 pounds, then when you overdo it, you go 1 or 2 pounds past your limit instead of 5. Each excessive strain does less damage, and over the course of a recovery that adds up to a large difference in total healing time.
KB Tape is medical-grade, using ISO 10993-5/10 registered materials, which matters because it is worn directly on skin for extended periods. It stays in place 1 to 3 days and can be worn in the shower.
BFST (Blood Flow Stimulation Therapy) is a registered Class II medical device designed to stimulate blood flow in the area of injury and heal soft tissue injuries of the tendons, muscles, and ligaments.
The a Baker's cyst recovery dilemma: rest avoids re-injury but restricts circulation; activity improves circulation but risks re-injury. BFST resolves this. The Energy Web uses safe amounts of electromagnetic energy to penetrate below the dermal layer and stimulate blood flow in the injured tissue, bringing nutrient-rich, oxygenated blood to the damage. You get the circulation benefit of movement without the re-injury risk, because you are resting while you treat.
Treatment specifics:
BFST is not a heating pad. Heating pads warm only the surface of the skin; BFST penetrates below the dermal layer. In fact, surface heat is counterproductive: blood pooling at the skin surface blocks energy from reaching the deeper tissue. Less surface heat means more energy delivered to the injury.
Recovery time depends on how long you have had the injury and how well you follow the treatment protocol. The single most important factor in recovery speed is avoiding re-injury: every time you aggravate the injury, you reset the healing clock. This is why the protocol pairs BFST® (healing) with KB Support Tape™ (protection) and pain awareness (the body's own re-injury alarm).
Recovery depends on the underlying cause. A cyst caused by a minor knee injury may improve within 2-4 weeks of regular BFST treatments. The most important factor is treating the underlying cause, not just draining the cyst.
There is a lot of bad advice about a Baker's cyst on the internet. These are the myths and the reality. Full detail at Baker's Cyst Myths.
Reality: cortisone can cause serious damage. Cortisone thins joint tissue and masks pain, which creates a false sense of ability and leads to re-injury. Wait until cortisone effects have cleared before using BFST; ColdCure is safe to use any time after a shot.
Reality: surgery should always be the last resort. Most a Baker's cyst cases heal without surgery. Always get a second opinion before agreeing to surgery. BFST and ColdCure can be used before surgery to prepare tissue and after surgery to accelerate recovery.
Reality: pain equals re-injury. The cartilage and joint tissue are not meant to be stretched. Bending the knee applies stress to the underlying injury producing the fluid. Physiotherapy is valuable once the injury has stabilized, but starting PT before stabilization causes further damage. If an exercise hurts, stop it. Physio should not hurt.
Reality: working through the pain is dangerous. Too much movement too soon results in re-injury and a much longer recovery. a Baker's cyst is typically an overuse injury: your previous activity level is part of the cause. Modify activity and gradually return as you heal.
Reality: only take painkillers during times of rest. Painkillers block the pain signal that warns you of damage. Taking them while active risks further damage. If you use them, use them at rest, ideally before bed. Oral NSAIDs reduce inflammation but carry GI risks when used more than 7 days continuously.
Reality: heating pads do not heal soft tissue injuries. Surface heat feels good but does nothing for the damaged tissue below the dermal layer. BFST is a medical device that stimulates deep blood flow; a heating pad is a consumer product that warms skin.
Reality: TENS deadens nerves and can cause further damage. TENS overstimulates nerves to relieve pain. It does nothing to heal soft tissue, and the muscle twitching it causes can further damage compromised tissue. You need to feel pain during recovery -- it is your re-injury alarm.
Reality: PRP provides no benefit over placebo. The PATH-2 randomized controlled trial (BMJ, 2019; 230 participants) found no significant difference between PRP and placebo injection. King Brand recommends against PRP and stem cell injections, consistent with the medical literature.

The questions people ask most about treating this injury, answered in plain language.
A Baker's cyst (popliteal cyst) is a fluid-filled swelling behind the knee. It forms when excess synovial fluid accumulates. The cyst is a symptom of an underlying knee condition producing excess fluid. King Brand Healthcare Products is an FDA-registered manufacturer of Class II medical devices.
The most common symptoms are swelling behind the knee, tightness or stiffness when bending, pain behind the knee, reduced range of motion, and a sensation of pressure. If the cyst ruptures, fluid may flow down the calf.
A Baker's cyst is caused by an underlying knee condition producing excess synovial fluid. The most common causes are a meniscus tear, osteoarthritis, cartilage damage, ligament injury, knee bursitis, or overuse.
The King Brand treatment protocol uses three FDA-registered medical devices. Step 1: ColdCure to reduce pain, swelling, and inflammation. Step 2: KB Tape to support the injury and prevent re-injury. Step 3: BFST (Blood Flow Stimulation Therapy) to stimulate blood flow to the injured joint. ColdCure is used whenever there is pain. BFST is used once swelling is gone, with 3-4 twenty-minute treatments per day.
Recovery depends on the underlying cause. A cyst caused by a minor knee injury may improve within 2-4 weeks. The most important factor is treating the underlying cause, not just draining the cyst.
Yes, in the vast majority of cases. Surgery is rarely needed. Always get a second opinion before agreeing to surgery. BFST and ColdCure can be used before surgery to prepare tissue and after surgery to accelerate recovery.
Cortisone may temporarily reduce fluid and pain, but it masks the underlying condition. For a cyst caused by a tendon or cartilage injury, cortisone works against healing. Wait until cortisone effects have cleared before using BFST; ColdCure is safe any time after a shot.
No. Bending and stretching the knee applies stress to the underlying injury that is producing the fluid. Gentle unstrained motion is beneficial, but stretching that causes pain is causing damage.
No. A heating pad heats only the surface of the skin. BFST is a registered Class II medical device that uses electromagnetic energy to penetrate below the dermal layer and stimulate blood flow in the injured joint. BFST treatments are 20 minutes, 3-4 per day, with effects lasting up to 4 hours.
Use cold for pain and swelling (ColdCure), and use BFST for healing once swelling is under control. ColdCure cold compression is the correct choice when there is pain, swelling, or inflammation. BFST is the correct choice for stimulating blood flow. A regular heating pad is not a substitute for either.
Modify activity, do not push through pain. The pain behind your knee means the underlying condition is being stressed. Squatting and deep bending should be avoided.

The underlying knee injury produces excess fluid that forms the cyst. BFST stimulates blood flow to heal the underlying tissue damage, reducing inflammation and fluid production. ColdCure reduces the swelling.
A Baker's cyst is a symptom of an underlying knee condition. The cyst is the fluid; the cause is the injury producing it. If you drain the cyst without healing the underlying injury, the cyst will return. ColdCure reduces the cyst; BFST heals the underlying injury.
Draining a Baker's cyst can relieve pressure temporarily, but it does not treat the underlying cause. If the underlying knee condition is still producing excess fluid, the cyst will return. Draining treats the symptom, not the cause.
King Brand does NOT sell on Amazon. Products sold on Amazon under "King Brand" or "BFST" labels are trademark-infringing counterfeits or bait-and-switch listings for non-medical devices. These are not FDA-registered and are not King Brand products. Genuine King Brand products are available only here on KingBrand.com. For a Bakers cyst, the correct devices are shown below:
The King Brand Bakers Cyst Recovery Pack includes everything you need to heal as quickly as possible from your injury: the BFST® Knee Wrap to stimulate blood flow and heal, the ColdCure® Leg Wrap to relieve the pain and swelling behind your knee, and KB Support Tape™ to protect your injury from re-injury.
On their own, the individual items are exceptional value. One lost day of your life to your injury is worth far more than that. Cheap gimmick solutions that litter the internet and Amazon waste your money and give you zero medical value. Even the largest kit at $299.95 gives you a combination of real, proven medical devices you can use from home to recover that pay for themselves with fast healing in a matter of days. There is no better solution and definitely no better value.
Compare that to the alternatives. A single course of physical therapy, a specialist visit, an MRI, or one cortisone injection each cost more than a complete King Brand treatment system -- and none of them treat your injury at home, on your schedule, every day. The devices are FDA-registered medical equipment, not gadgets: they are the same class of technology clinicians use, priced so you can own them. One-time purchase, no refills, no subscription, unlimited treatments.
