Cobra 2 Unloader Knee Brace, Right Knee, OA Knee Support

The Cobra 2 Unloader Knee Brace is a low-profile, lightweight orthosis designed to reduce pain and pressure in individuals with unicompartmental osteoarthritis (OA) of the knee. The single-strapping design simplifies donning and adjustment while helping achieve a precise, secure fit. Three-point leverage mechanics offload pressure from the affected compartment of the knee joint, reducing pain during walking, standing, and daily activity. Valgus and varus adjustment allows the brace to be customized to the individual’s alignment for optimal unloading. Right knee.

Indications

Indicated for individuals with unilateral compartment osteoarthritis of the knee who require conservative management of medial or lateral compartment pain through mechanical unloading. Use as directed by your physician or orthopedic specialist.

Ideal For

Individuals with medial or lateral compartment knee osteoarthritis who experience pain during walking, stair climbing, or prolonged standing and want a conservative, non-surgical option to reduce compartment loading and improve daily function will find the Cobra 2’s three-point leverage mechanism provides meaningful pain relief by mechanically offloading the affected compartment. Patients who have been prescribed an unloader knee brace by their orthopedic surgeon or physiatrist as part of a conservative OA management plan — either as a standalone intervention or in conjunction with physical therapy, injections, or weight management — will find the single-strap design easier to don and adjust independently compared to multi-strap unloader braces. Active adults with unicompartmental knee OA who want to continue participating in low-impact activities such as walking, cycling, or golf while managing their knee pain will find the low-profile, lightweight construction less obtrusive during activity than bulkier unloader designs. Individuals who have tried standard knee sleeves or hinged knee braces and found them insufficient for managing compartment-specific OA pain will find the unloading mechanism of the Cobra 2 addresses the underlying biomechanical cause of their discomfort more directly. Patients awaiting knee replacement surgery who need interim pain management and functional support during the pre-operative period will find the Cobra 2 a practical tool for maintaining mobility and quality of life while managing OA symptoms.

Frequently Asked Questions

What is an unloader knee brace and how does it work?
An unloader knee brace uses a three-point leverage system to apply a corrective force to the knee joint, shifting load away from the damaged compartment (medial or lateral) and toward the healthier compartment. This mechanical offloading reduces the compressive forces on the arthritic cartilage, which can significantly reduce pain during weight-bearing activity. The brace does not treat the underlying OA but manages symptoms by altering the biomechanics of the knee during use.

How do I know if I need a medial or lateral unloader brace?
The type of unloader brace needed depends on which compartment of your knee is affected by OA. Medial compartment OA (the most common type) causes pain on the inner side of the knee and requires a valgus-correcting unloader brace. Lateral compartment OA causes pain on the outer side and requires a varus-correcting brace. Your orthopedic surgeon or physiatrist will determine which compartment is affected and prescribe the appropriate brace configuration.

How do I adjust the valgus and varus settings?
The Cobra 2 features adjustable valgus and varus settings that allow the brace to be tuned to the individual’s alignment and the degree of unloading required. Adjustment should be performed under the guidance of your prescribing physician, orthotist, or physical therapist to ensure the correct amount of corrective force is applied for your specific condition.

Is this brace available for the left knee?
This listing is for the right knee only. If you need a left knee unloader brace, please order the corresponding left-side version. Using a right brace on the left knee will result in improper fit and ineffective unloading.
