What Is an Unloader Knee Orthosis?
An unloader orthosis uses a three-point mechanical pressure system to shift load away from the affected knee compartment, helping relieve pressure, reduce pain, and improve alignment and motion control. These orthoses are crafted using lightweight materials like aluminum or carbon fiber with adjustable hinges and straps.
How It Works
- Load Redistribution
Applies corrective forces via orthosis hinges and straps to shift joint mechanics away from compromised compartments. - Dynamic Control
Advanced models include adjustable dynamic straps or Boa-type dials for precise tension and offloading control. - Adjustability & Comfort
Straps, sizing, and padding are optimized for secure fit, non-slip alignment, and long-term comfort.
Common Clinical Applications
- Medial (or less commonly lateral) unicompartmental knee osteoarthritis
- Degenerative cartilage injuries, meniscus tears, or avascular necrosis
- Patients seeking conservative management to delay knee joint replacement
- Post-operative rehabilitation or instability support following knee-related surgery
Response & Outcomes
- Many individuals experience reduced pain and improved mobility, without immediate need for surgery.
- Patients with symptomatic arthritic wear often find substantial improvement in daily activity tolerance and joint mechanics.
