A knee brace with hinges differs from a basic compression sleeve in one key way: the hinges. These are rigid or semi-rigid components positioned on the medial and lateral sides of the knee that restrict movement in directions the joint is not designed to travel. The knee is primarily a hinge joint that allows flexion and extension, with medial and lateral stabilizing structures — including the collateral ligaments — that resist side-to-side stress.
For people who need more than compression alone, a hinged design provides structural support that a sleeve cannot. The hinge does the stabilizing work, while the surrounding material handles fit, comfort, and contact with the leg. The result is a brace that can be worn through daily activity without feeling overly rigid or restrictive.
Functional vs. Post-Op: Two Different Use Cases
Not all hinged knee braces serve the same purpose, and understanding that distinction upfront saves time when narrowing down your options.
A functional knee brace is designed to be worn during daily activities, walking, and lower-impact movement. It provides support without restricting the range of motion the user needs to get through the day comfortably. A post-op hinged knee brace takes a more controlled approach: it allows a care team to set precise limits on how far the knee bends or extends, keeping the joint within a protected range during the early stages of recovery after a procedure.
Both types are available in our lineup, and the right choice depends entirely on where you are in your routine.
Hinged Knee Braces At Ortho Bracing
We carry two DonJoy hinged knee brace options. Here is a closer look at each.
DonJoy Sport Drytex Economy Hinged Knee Wrap Around
The
DonJoy Sport Drytex Economy Hinged Knee Wrap Around is a functional hinged knee brace built for everyday wear and lower-impact activity. Bilateral polycentric hinges provide medial and lateral stability while allowing the knee to move through its natural range of motion.
The brace is made from DonJoy's Drytex material — a neoprene alternative with a nylon core and polyester Lycra fabric — offering improved airflow and breathability compared to standard neoprene. This makes it well-suited for all-day wear, particularly for people who find warmer brace materials uncomfortable over extended periods. The wraparound design allows application without removing footwear, and the adjustable straps let the user tailor the fit throughout the day.
Key features include:
- Bilateral polycentric hinges for medial and lateral support
- Drytex material for breathability and comfort during extended wear
- Wraparound application with no need to remove shoes
- Adjustable straps for a customizable fit
- Optional popliteal cutout to reduce bunching behind the knee
- Aluminum uprights that can be removed for washing
- Available in multiple sizes
DonJoy X-ACT ROM Post-Op Hinged Knee Brace
The
DonJoy X-ACT ROM Knee Brace is a post-op hinged knee brace engineered for use following knee procedures. It is built around precise range-of-motion control, with durable aluminum hinges that a care provider can set to specific extension and flexion limits at each stage of recovery.
Anti-migration foam lining and a dynamic suspension frame contour naturally to the leg's shape, keeping the brace in place throughout the day without constant readjustment. Swivel-action buckles allow for fast, efficient application, and four independently telescoping sliders let the straps be positioned away from the surgical site. The brace fits both left and right knees in a universal size that accommodates most adult builds.
Key features include:
- Durable aluminum hinges with adjustable range-of-motion settings
- Extension settings from -10° to 90°; flexion settings from -10° to 120°
- Anti-migration foam lining to reduce slippage throughout the day
- Dynamic suspension frame that contours naturally to the leg
- Swivel-action buckles for fast, secure application
- Four independently telescoping sliders for strap placement flexibility
- Universal size, fits left or right knee
- Lightweight construction suitable for early post-procedure use
Selecting The Right Hinged Knee Brace For Your Situation
Selecting the right hinged knee brace comes down to what your knee actually needs from the brace on a daily basis. The two units in our lineup are built for distinctly different situations, and knowing where you stand makes the decision straightforward.
Everyday Wear And Lower-Impact Activity
The DonJoy Sport Drytex Economy Hinged Knee is the practical choice for people who need consistent knee support during daily movement. The Drytex material keeps it comfortable over long periods, the wraparound design makes it easy to apply, and the polycentric hinges deliver lateral stability without adding significant bulk. For anyone looking for a dependable knee brace with hinges for daily use, this is a well-built option at a reasonable price. For a broader comparison of available options, our resource on the
best hinged knee braces is a useful reference.
Structured Recovery Following A Knee Procedure
The DonJoy X-ACT ROM is purpose-built for the post-operative period. The adjustable aluminum hinges allow a physical therapist or surgeon to configure the exact range of motion appropriate for each phase of recovery. The anti-migration foam keeps the brace in place through daily movement, and the telescoping sliders and swivel buckles make application manageable even early on. If your care provider has recommended a post-op hinged knee brace, this unit is designed specifically for that role.
Hinged Knee Braces For ACL And MCL Recovery
A hinged knee brace for ACL or MCL support is a common consideration, and both units in our lineup can be relevant depending on the stage of recovery. The ACL is one of the most commonly injured structures in sports medicine and does not heal when damaged on its own, which is why structured external support during recovery and rehabilitation is a key part of many care protocols.
The DonJoy X-ACT ROM is specifically designed for post-operative use following knee procedures, including those involving the ACL or MCL. The adjustable range-of-motion settings let the care team control the flexion and extension the knee undergoes at each stage of recovery, making it a structured option for the early and mid stages of recovery.
The DonJoy Sport Drytex Economy Hinged Knee provides bilateral structural support during daily activities and lower-impact movement. Its polycentric hinges offer medial and lateral stability that many people find practical during the later stages of a recovery routine or for general knee support during activity.

Before You Place Your Order
Getting The Right Size
The DonJoy Sport Drytex Economy Hinged Knee comes in multiple sizes. Measure your thigh and calf six inches above and below the kneecap with a flexible tape measure, then refer to the sizing chart on the product page. If you are between sizes or have questions about fit, reach out before ordering. The DonJoy X-ACT ROM is a universal size that fits most adult builds and works on both the left and right knee.
Working With Your Care Provider
The DonJoy X-ACT ROM is a post-operative brace, and its range-of-motion settings are intended to be adjusted by a physician or physical therapist. Coordinating with your care provider before and after delivery is recommended to make sure the brace is configured correctly for your recovery stage.
Adding Cold Therapy To Your Setup
