Knee Braces Made for the Mats
Jiu-jitsu is hard on knees. Guard retention, takedown defense, scrambles, knee-on-belly — every position loads your joints in ways most sports never touch. Whether you're a white belt learning to shrimp or a black belt competing at Masters, the right knee brace keeps you training instead of sitting out.
Support for Every Style of Rolling
BJJ demands a knee brace that moves with you — rigid enough to protect, flexible enough to let you play guard. We offer three levels of support so you can match your brace to your training:
- Hinged Knee Brace — Maximum lateral stability for grapplers recovering from ligament injuries or dealing with chronic knee instability. The dual aluminum hinges prevent hyperextension during stacking and guard passes while still allowing the flexion you need for closed guard and deep half.
- Spring Knee Brace — Bilateral spring stabilizers provide dynamic support that returns energy as you move. Perfect for active guard players and competitors who need stability without sacrificing speed during transitions and scrambles.
- Compression Knee Sleeve — Medical-grade knitted compression keeps joints warm, reduces swelling, and provides proprioceptive feedback during rolls. The go-to choice for daily training, drilling, and injury prevention.
Why Grapplers Trust Old Bones Therapy
OBT was born in action sports culture. We understand that you need gear that performs under pressure — not bulky medical devices that restrict movement. Our knee braces are low-profile enough to wear under a gi or during no-gi sessions, with flat-seam construction that won't catch or snag during rolls.
Every brace uses medical-grade compression that improves blood flow and reduces inflammation, helping your knees recover between training sessions so you can get back on the mats faster.
Post-Training Recovery
Hard rolls take a toll. Our Ice Sleeve delivers targeted cold compression to reduce swelling and soreness after intense training sessions. Pair it with your knee brace for a complete training-to-recovery system.
HSA/FSA Eligible
All of our knee braces are HSA and FSA eligible — use pre-tax health dollars for your training gear. Check out our skateboarding knee braces for another action sport we support. View our sizing guide to find your fit.
FAQs
What is the best knee brace for BJJ?
For BJJ, it depends on your needs. A hinged knee brace provides the most stability — ideal for grapplers with ligament injuries or chronic knee issues. A spring knee brace offers dynamic support that moves with you during guard play and scrambles. A compression knee sleeve is best for daily training and injury prevention. Most BJJ practitioners start with a compression sleeve and upgrade to hinged or spring support if they have an existing injury.
Can you wear knee braces in jiu-jitsu competitions?
Yes — knee braces and compression sleeves are allowed in most jiu-jitsu competitions, including IBJJF events. Soft compression sleeves and neoprene braces are universally accepted. Hinged braces with hard components may need to be checked by referees at some tournaments, but are generally allowed if they don't pose a risk to your opponent. Always check the specific ruleset for your competition.
How do knee sleeves help in BJJ?
Knee sleeves help BJJ practitioners in three ways: they keep the joint warm and lubricated during training (reducing injury risk during explosive movements), they provide compression that reduces swelling after hard rolls, and they offer proprioceptive feedback that improves your awareness of knee position during guard play and scrambles. Many grapplers wear them preventatively, not just for existing injuries.
Should I wear a knee brace for no-gi jiu-jitsu?
Yes — knee braces are arguably more important for no-gi than gi. Without the gi fabric to grip, opponents rely more on leg locks, heel hooks, and knee-twisting submissions that put significant stress on knee ligaments. A compression sleeve or spring brace provides baseline protection during no-gi training. If you've had a previous knee injury, a hinged brace is recommended for no-gi sessions.
Are knee braces HSA or FSA eligible for martial arts training?
Yes — all Old Bones Therapy knee braces are HSA and FSA eligible regardless of whether you're using them for martial arts training, injury recovery, or daily wear. Knee braces qualify as eligible medical expenses under IRS guidelines. You can purchase directly with your health spending account card at checkout.
