Knee Braces & Supports: Understanding the Different Types and What They Do
Not all knee braces are the same. Each type is engineered for a specific purpose, from controlling motion after surgery to stabilizing a loose ligament to relieving kneecap pain during a run. Learn what each type does so you can find the right match.
Shop All Knee BracesHinged Knee Braces
Hinged knee braces use bilateral hinges on both sides of the knee to control motion and provide structural stability. They are the most commonly prescribed type for ligament and meniscus injuries.

Compression Sleeves & Knee Supports
Compression sleeves are pull-on supports made from knit or neoprene fabrics that provide graduated pressure around the knee. They are the most versatile and widely used type of knee support.
Patellar Straps & Stabilizers
Patellar supports target the kneecap and patellar tendon specifically. Straps apply focused pressure below the kneecap, while stabilizers use buttress pads to correct kneecap tracking.

Post-Operative & ROM Knee Braces
Post-op braces are rigid or semi-rigid devices with precision range of motion (ROM) hinges that control exactly how far your knee can bend and straighten during surgical recovery.
Knee Immobilizers
Knee immobilizers are full-length rigid supports that hold the knee completely straight. They provide maximum immobilization for fractures and acute injuries.
Hyperextension & Rehabilitator Braces
Hyperextension braces are specialized devices that prevent the knee from bending too far backward. They are designed for both short-term rehabilitation and long-term daily use.

Sizing & Fit Tips
Sizing methods vary by brace type and brand. Always check the specific product's sizing chart, but here are general guidelines.
Compression Sleeves
Sized by circumference at the center of the kneecap while standing. If between sizes, size down for a snugger fit.
Hinged Braces
Require kneecap circumference plus measurements above and below the knee. The hinge must align with your knee joint line.
Post-Op & ROM Braces
Sized by thigh and calf circumference plus leg length. Telescoping designs adjust, but hinge alignment is critical.
Patellar Straps
Most are one-size-fits-most with adjustable closures. Position the pad directly over the patellar tendon below the kneecap.
Insurance and Payment Options
Many of our knee braces qualify for insurance reimbursement or tax-advantaged health accounts.
PDAC Approved
Many of our knee braces carry PDAC approval, which means they meet Medicare coding standards for reimbursement through your insurance provider.

Start with your condition or symptom. Ligament injuries (ACL, MCL, PCL) typically need a hinged brace. Kneecap pain and tracking issues respond to patellar stabilizers or straps. Post-surgical recovery requires a ROM brace. Arthritis and general soreness often benefit from compression sleeves. If you are unsure, browse our condition-specific collections or contact our brace specialists.
A functional knee brace is a hinged brace designed to support an injured or reconstructed ligament during activity. Unlike a post-op brace that restricts motion during healing, a functional brace allows full or near-full range of motion while providing mechanical reinforcement against forces that stress the injured ligament. They are most commonly prescribed for ACL-deficient or ACL-reconstructed knees during the return-to-sport phase.
It depends on the type. Compression sleeves and lightweight hinged braces with breathable fabrics are generally comfortable for all-day wear. Post-op ROM braces are designed for extended wear during recovery, often including overnight. Patellar straps are typically worn during activity only. For any brace, give your skin periodic breaks if you notice irritation.
ROM stands for range of motion. A ROM knee brace has adjustable hinges that let your surgeon set precise limits on how far your knee can bend and straighten. These braces are primarily used after knee surgery to protect the repair while allowing controlled, progressive movement. Settings are gradually increased in 10 to 15 degree increments as tissues heal. ROM braces are essential for ACL reconstruction, meniscus repair, and total knee replacement recovery.
Measurement methods vary by brace type and brand, so always check the specific product's sizing instructions. As a general starting point, most braces require a circumference measurement at the center of your kneecap with the leg straight and weight evenly distributed. Some also require measurements above and below the knee, or leg length for telescoping designs. Use a flexible tape measure pulled snug without compressing the tissue.
