✅ Feature Highlight
- Precise ROM (Range of Motion) Control for Safe Rehabilitation
BCI ACL knee brace isn’t just about rigid support — it gives you fine-tuned control over motion. With plug-in ROM stops, you can lock extension at 0°, 10°, 20°, 30°, or 40° and limit flexion at up to eight settings (0°, 10°, 20°, 30°, 45°, 60°, 75°, 90°).
For early rehab when motion must be restricted, the brace also supports immobilization at 0°–30°. As your healing progresses, simply adjust the stops to unlock additional range.
This dual functionality (immobilization + adjustable motion) helps balance protection and mobility, letting you guard against hyperextension, control excessive bending, and progressively restore natural movement.
Frequently Asked Questions
Q1. What conditions is the BCI Functional ACL Knee Brace designed for?
A1. This brace provides stability and protection for ACL, MCL, PCL, and LCL ligament injuries. It’s also ideal for post-surgery rehabilitation, meniscus tears, and general knee instability. The adjustable design helps manage range of motion (ROM) during recovery.
Q2. How do the adjustable range of motion (ROM) hinges work?
A2. The brace includes plug-in extension stops (0°, 10°, 20°, 30°, 40°) and flexion stops (0°–90°) that control knee bending and straightening. You can also immobilize the knee at 0°–30° for early recovery stages, then gradually increase movement as healing progresses.
Q3. Do I need a prescription to purchase this brace?
A3. No, you can order this medical-grade ACL knee brace directly without a prescription. It’s FDA-approved and suitable for home use, physical therapy, and athletic recovery.
Q4. How do I choose the correct size?
A4. Measure your thigh circumference 6 inches above the kneecap and calf circumference 5 inches below the kneecap. Refer to the “Size Chart +” on this page. If you are between sizes, we recommend selecting the larger one for comfort and a secure fit.
Q5. Is this brace HSA/FSA or insurance eligible?
A5. Yes, this brace is FDA-approved and coded under HCPCS L1845 or L1852, which makes it eligible for HSA/FSA reimbursement. Many insurance providers also recognize it as durable medical equipment (DME).
Q6. What design features improve comfort and stability?
A6. The brace uses a polycentric hinge system that mimics natural knee movement, with silicone-grip liners to prevent slippage. Condyle pads support the sides of the knee, and breathable straps ensure comfort during long wear.
Q7. How do I clean and maintain the brace?
A7. Hand wash the pads and straps with mild soap and cold water. Do not machine wash or tumble dry. Air dry completely before reuse. Regularly check hinges and straps for wear and replace parts as needed.
