Knee splint OA Nano™

XSSL

Overview
Material science and ergonomic design combine to deliver a lightweight knee unloading brace for patients with mild to moderate knee osteoarthritis. The malleable magnesium and aluminium frame allows anatomical adjustment for a close fit while providing mechanical strength to off‑load the affected compartment. OA Nano™ is intended to support patient activity and improve adherence by offering comfortable, non‑invasive symptom relief derived from performance bracing technologies.

Indication
Indicated for mild to moderate unicompartmental knee osteoarthritis. PDAC Assigned Codes: L1845 and L1852.

90 Day Test Drive and Ease of Use
DonJoy offers a 90‑day Test Drive to confirm fit and patient satisfaction. Proper fitting is critical to avoid slipping, pressure points or skin issues; correctly sized OA braces aim to reduce pain and improve function.

Features & Benefits

• Custom fit — Malleable magnesium frame enables cuff molding for an intimate, patient‑specific fit.
• Ultra lightweight — Design and materials minimize device weight (approx. 402 g) for increased wearability.
• Secure suspension — Contoured cuff geometry reduces migration during daily activities.
• Mechanical off‑loading — Frame architecture provides reliable off‑load of the affected compartment.
• Controlled adjustment — DonJoy Adjuster™ technology allows precise varus/valgus correction to shift load away from the damaged area.
