Dynamic Unloading Brace

- Clinically validated pain relief
- High patient satisfaction
- Easy to fit, apply, and use Learn more
Description
The OA Spiral combines unloading in the tibiofemoral joint with realignment in the patellofemoral joint.


Tibiofemoral: The OA Spiral uses a three-point leverage system and a non-elastic strap to pull the knee out of varus or valgus and decrease pain.¹
Patellofemoral: Among patients with tibiofemoral OA, 91% also have radiographic patellofemoral OA.² BioSkin's Q strap has been clinically proven to decrease pain in the PF joint by supporting proper patellar alignment and increasing joint surface contact.³



The lightweight hinge and thin, breathable materials yield a product that is comfortable and easy to wear, even under clothing. The strap and buckle design makes donning and doffing easy for patients who struggle with dexterity. The OA Spiral is also designed for longevity with easily replaceable Velcro panels so the patient can get years of use from the same brace.

Application Instructions

1. Insert leg through the inner knee sleeve (optional), positioning the hinge at the mid patella. For medial application, place the hinge on the inside of the knee. For lateral application, place the hinge on the outside of the knee.

2. Sitting on the edge of a chair, adjust the front closure flaps to a comfortable level of compression. We recommend securing the lower flaps first for easy application.

- If using the Q strap, apply it to the brace before securing the front-closure flaps closest to the patella. To apply, secure the outer Velcro-tab of the Q strap to the side of the brace. Pull the upper and lower portions of the Q strap above and below your patella to apply a corrective force. Then close the front-closure flaps of the OA Spiral and continue the application process.

3. Gently pull the spiral strap behind your calf, around your knee, and over the top of your thigh and attach the magnetic buckle.

4. Place your foot flat on the ground with your heel slightly in front of your knee and then apply tension to the spiral strap. Pull just enough to apply tension to the strap; be sure not to over-tighten.

5. Test joint unloading by extending leg.

If more unloading is desired, tension the strap a little bit more. A little bit goes a long way. If less unloading is desired, slightly loosen the strap.

To remove the brace, bend the knee to release tension in the spiral strap and lift the tab on the magnetic buckle to detach. This will keep the strap at the correct tension mark for repeatable tension of the strap. Undo the front closure flaps and remove the brace.
