Knee braces come in a variety of types, shapes, and sizes, each designed to provide support and relieve pressure on the knee joint. If you're experiencing new or worsening knee pain, it's important to consult a healthcare provider. They can identify the underlying cause and recommend the most appropriate type of brace for your condition.
What Is a Knee Brace?
A knee brace is a medical device designed to stabilize and support the knee joint, often used after an injury or surgery. Healthcare providers may recommend a knee brace—also known as an orthosis—to protect the knee, reduce pain, or improve mobility.
One of the most commonly prescribed types for people with knee arthritis is the unloader brace, which helps relieve pressure on the affected part of the joint.
Knee braces are used to treat or manage a variety of conditions, including:
Ligament injuries or knee sprains
Patellofemoral pain syndrome
Kneecap instability or dislocations
Patellar tendinitis or other tendon issues
Peripheral neuropathy
Knee arthritis
Joint hypermobility syndrome
Ehlers-Danlos syndrome
In some cases, a knee brace may also be recommended to reduce the risk of sports injuries or help manage chronic knee pain.
While a knee brace can offer valuable support, it is not a replacement for professional medical care. If you’re experiencing knee pain—especially if it’s new or getting worse—consult a healthcare provider. They will accurately diagnose the issue and recommend the most appropriate brace based on your specific condition.
A knee brace is designed to support your knee joint and help maintain proper alignment. By limiting excessive or sudden movement, it reduces stress on the joint and surrounding structures. Most braces are made with rigid plastic or metal components, along with soft padding and adjustable straps to ensure a secure, comfortable fit.
The level of support and resistance a knee brace provides depends on the type of brace and your specific condition.
There are several types of knee supports, each designed for different needs:
Unloader Knee Braces
Commonly prescribed for knee arthritis, these braces help redistribute weight away from the damaged part of the joint, easing pressure and reducing pain.
Patellofemoral Knee Braces
These braces support the kneecap and front of the knee, helping manage pain and instability in that area.
Knee Immobilizers
Often used after surgery, immobilizer braces are rigid and limit most or all knee movement during recovery.
Functional Knee Braces
Designed for people recovering from an injury, these braces control motion and prevent the knee from moving beyond a safe range.
Prophylactic Braces
Worn preventatively, especially by athletes in contact sports like football or rugby, these braces aim to reduce the risk of injury. Always consult a provider before using one for sports.
Knee Sleeves
Made from elastic, compressive materials, these are not true braces but offer mild support and compression. Commonly used for minor discomfort or swelling, they’re widely available over-the-counter.
Your healthcare provider will recommend the most appropriate brace based on your diagnosis. Some braces are available over-the-counter, while others require a prescription and custom fitting for proper support and comfort.
Most knee braces fasten with Velcro® or elastic straps and should feel snug without being overly tight. A properly fitted brace:
Should not cause pain or cut off circulation
May feel unusual at first, especially if it gently realigns the joint
Should never make your knee pain worse
Tip: Always consult your healthcare provider or physical therapist before using a knee brace for the first time. They can show you how to put it on correctly and adjust to moving with it comfortably and safely.
Knee braces are a simple and effective way to provide additional support to your knee joint. They can offer several benefits, including:
Pain relief and reduced stiffness, particularly for individuals with knee arthritis
Stabilization after an injury or surgery to promote safer healing
Improved confidence and peace of mind during physical activity, especially in sports or after a previous injury
Support during daily movement, which can help people feel more secure and reduce the fear of re-injury
Even though scientific studies haven’t definitively proven that knee braces prevent injury, many people report feeling more stable and protected, which helps them stay active and engaged in their routines.
While complications are rare, wearing a knee brace can sometimes lead to minor issues, especially if it doesn’t fit properly or is worn for too long:
Skin irritation from friction or heat buildup
Pressure sores due to prolonged tightness or rubbing
Nerve compression, which can cause numbness or tingling in the leg
To minimize risks, it’s important to work with a healthcare provider or physical therapist to choose the right type of brace and ensure it fits correctly.
The length of time you’ll need to wear a knee brace depends on your specific condition or injury. Your healthcare provider will give you a personalized recovery timeline based on your diagnosis, whether you’ve had surgery, or the severity of your injury.
In some cases, you may only need to wear a brace during physical activity or sports. In others, your provider may recommend wearing it more consistently to ensure proper healing and joint support.
Your provider will guide you on:
How often to wear the brace
When it’s safe to reduce use
When you can resume full activity without support
Always follow your provider’s instructions closely to support a safe and successful recovery.
Knee braces are available in a wide range of shapes, sizes—and even colors—allowing for some personal preference. Regardless of the reason you need one, a properly fitted knee brace can provide valuable support and help you stay active with greater safety and confidence.
Your healthcare provider or physical therapist will guide you on how to correctly wear and adjust your knee brace to ensure it offers the right level of support and protection for your knee joint.
