What this is
Ortho Net is an orthopedic braces and supports resource covering ankle braces, knee braces, night splints, back supports, wrist braces, shoulder supports, elbow braces, foot orthotics, and plantar fasciitis treatment, with plain guidance for anyone navigating an injury or recovery and trying to understand which support is right for their situation.
By body part
Braces and supports by joint
Find the guide for the joint you are supporting. Each covers the brace types used there, common conditions, and how to choose the right fit.
Back Supports
Back Supports
A back brace or lumbar support can reduce pain during an acute muscle strain by limiting spinal motion and offloading the muscles around the injury.
Wrist Braces
Wrist Braces
A wrist splint for carpal tunnel syndrome holds the wrist in a neutral or slightly extended position, which opens the carpal tunnel as much as possible and reduces pressure on the median nerve.
Shoulder Supports
Shoulder Supports
Shoulder supports range from simple slings that rest the arm after acute injury or surgery, to neoprene compression sleeves for rotator cuff soreness, to specialized abduction braces that hold the arm away from the body during rotator cuff repair recovery.
Elbow Braces
Elbow Braces
A tennis elbow strap, also called a counterforce brace, is a padded band worn around the upper forearm, about two to three finger-widths below the elbow.
By condition
Common conditions and what helps them
Night splints, arch supports, and orthotics address specific conditions. These guides explain what each condition involves and how supports help.
Plantar Fasciitis
Plantar Fasciitis
Plantar fasciitis is an irritation of the plantar fascia, the thick band of tissue running along the bottom of the foot from the heel to the toes.
Achilles Tendinitis
Achilles Tendinitis
Orthopedic supports for Achilles tendinitis reduce the load and stretch placed on the tendon during activity and rest.
Night Splints
Night Splints
A night splint holds the foot and ankle at roughly 90 degrees while you sleep, keeping the plantar fascia and Achilles tendon in a lengthened position overnight.
Foot Supports
Foot Supports
For plantar fasciitis, heel pain, and some cases of flat feet or high arches, foot orthotics and arch supports reduce strain on the plantar fascia and distribute pressure more evenly across the sole.
Why plain-language guidance
Understanding what a brace does before you buy one
Most people choose an orthopedic brace based on where they hurt rather than why. A compression sleeve for ankle instability provides comfort but no mechanical support. An unloader knee brace for diffuse arthritis may load the wrong compartment. A wrist splint held at the wrong angle worsens carpal tunnel symptoms instead of relieving them.
This resource explains the mechanics first: what each category of brace is designed to do, which conditions it addresses, and how to choose within that category. From there it is easier to have an informed conversation with a clinician, or to select a well-matched over-the-counter device for a mild, well-characterized condition. Explore the ankle braces guide, the night splints guide, or the how-to-choose guide to get oriented.

A fuller guide to orthopedic braces and supports
If you are new to orthopedic bracing, the sections below go deeper on how the categories work, common conditions, night splints, and how to choose. Open whichever is useful.
Orthopedic braces by body part: a quick orientation
Orthopedic braces and supports are organized in this guide by the body part they serve, because the mechanical need of a joint determines which class of device is appropriate. An ankle brace addresses the ligaments, muscles, and tendons around the ankle joint; a knee brace addresses the knee; a back support addresses the lumbar spine; wrist, shoulder, and elbow braces each address their respective joints.
Within each body part, the device type matters as much as the body part itself. A knee sleeve provides compression but no structural stability; a hinged knee brace protects ligaments; an unloader brace shifts weight away from damaged cartilage. Choosing the wrong type for a given condition can give false confidence in a joint that needs more mechanical control, which is why understanding the categories matters before selecting a specific product.
Common conditions and the braces that help them
Plantar fasciitis is one of the most common reasons people seek orthopedic support. It causes stabbing heel pain with the first steps of the morning, and a combination of night splints, arch supports, and calf stretching is the standard first-line treatment. Achilles tendinitis similarly benefits from night splints and heel lifts, combined with the eccentric strengthening program that drives tendon remodeling.
Ankle sprains are the most common sports injury, and ankle braces are the most studied form of prophylactic bracing: lace-up and semi-rigid ankle braces consistently reduce the re-sprain rate in athletes with a prior sprain. Tennis elbow and golfer's elbow are managed with counterforce elbow straps during activity alongside tendon-specific rehabilitation. Knee osteoarthritis can be managed with sleeves for mild symptoms or unloader braces for unicompartmental disease. Carpal tunnel syndrome responds well to neutral-position wrist splinting, particularly worn at night.
Night splints: how they work and why morning pain happens
When you sleep, the foot naturally falls into a plantarflexed position, with the toes pointing downward and the plantar fascia and Achilles tendon in a shortened, slack state. The tissue adapts to that shortened position overnight. When you stand up in the morning, these structures are suddenly stretched to their functional length, which is the source of the sharp, stabbing first-step pain that is the hallmark of both plantar fasciitis and Achilles tendinitis morning stiffness.
A night splint interrupts this cycle by holding the foot at 90 degrees or in slight dorsiflexion throughout sleep. When you rise in the morning, the tissue is already at or near its working length, so the sudden-stretch pain is dramatically reduced. Boot-style night splints provide reliable positioning at the cost of bulk; sock-style dorsal splints are more comfortable to sleep in, which often makes them more effective in practice because of better nightly compliance.
How to choose the right brace for your condition
The most important step in choosing a brace is knowing your diagnosis. The same symptom location can have multiple underlying causes, and each cause may call for a different type of device. Knee pain from patellofemoral syndrome calls for a patella-stabilizing brace; knee pain from osteoarthritis may call for an unloader brace; knee pain from a ligament sprain may call for a hinged brace. Buying a compression sleeve for any of these without a diagnosis is unlikely to cause harm, but it may provide false reassurance and delay appropriate care.
Once you have a diagnosis, match the device category to the mechanical need. Compression manages swelling and provides proprioceptive feedback. Rigidity limits motion and protects ligaments. Positioning devices hold a joint at a specific angle to manage nerve or tendon conditions. Offloading devices redistribute forces away from a damaged structure. Read the sizing chart for the exact product, and seek clinical guidance for post-surgical devices and custom orthoses.
Sports bracing and injury prevention
Prophylactic bracing, wearing a brace to prevent an injury before it happens, has its strongest evidence base in ankle bracing for team sport athletes. Multiple randomized trials have shown that lace-up and semi-rigid ankle braces reduce the rate of ankle sprains in basketball, volleyball, and soccer, particularly in athletes with a prior sprain history. The protective effect is meaningful enough that many athletic trainers and team physicians routinely brace players with a prior ankle sprain history for practices and games.
For the upper extremity, counterforce elbow straps for tennis elbow allow athletes to continue playing while tendon rehabilitation proceeds. Wrist braces that limit hyperextension are used in contact sports and in skateboarding and snowboarding falls. Return-to-sport protocols after specific injuries, such as ACL reconstruction or shoulder dislocation, typically include a period of protective bracing as part of a graded return-to-activity plan.
What this resource is, and what it is not

Questions answered
Common questions about orthopedic braces
What is an orthopedic brace?
An orthopedic brace is a device worn around a joint or body segment to limit motion, provide compression, reduce pain, or protect a healing structure. Braces range from simple elastic sleeves to rigid hinged devices and are used for injuries, post-surgical recovery, chronic instability, and pain management in conditions such as arthritis and tendinopathy.
Do I need a prescription to buy an orthopedic brace?
Most over-the-counter orthopedic braces, including ankle braces, knee sleeves, wrist splints, and counterforce elbow straps, are available without a prescription. Prescription or custom orthoses, such as custom-molded orthotics, post-surgical hinged braces with specific range-of-motion settings, and rigid spinal orthoses, generally require a clinician's order and fitting. If you are unsure whether an over-the-counter device is appropriate for your specific condition, consult a healthcare provider.
What is a night splint and who needs one?
A night splint holds the foot and ankle at roughly 90 degrees while you sleep, preventing the plantar fascia and Achilles tendon from shortening overnight. It is most commonly used for plantar fasciitis and Achilles tendinitis, both of which cause morning heel pain caused by tissue that tightens during rest. Consistent nightly use for four to six weeks reduces morning pain significantly in most users.
What is the difference between a brace and an orthotic?
The terms overlap in everyday use. A brace typically refers to a device worn around a limb joint, such as a knee brace or ankle brace, to limit motion or provide stability. An orthotic, or orthosis, often refers to an insole or arch support placed inside a shoe to modify how forces pass through the foot and lower limb. Both are prescribed or selected based on what the body part needs mechanically.
Can I use a brace instead of surgery?
For many conditions, conservative treatment including appropriate bracing, physical therapy, and activity modification allows people to avoid surgery. Plantar fasciitis, Achilles tendinopathy, mild-to-moderate ankle instability, and knee osteoarthritis are examples where bracing is a meaningful part of non-surgical management. Whether surgery is ultimately needed depends on the severity of the condition, the response to conservative treatment, and individual factors. A healthcare provider should guide that decision.
How do I know what size brace to buy?
Brace sizing varies by manufacturer and by body region. Most braces are sized by circumference measurement at a specified point, such as the mid-patella for a knee brace or the shoe size for an ankle brace. Always read the specific sizing chart for the exact product you are purchasing, as sizes differ between brands. A brace that is too loose provides no mechanical benefit; one that is too tight can restrict circulation.
