Measure loosely on bare skin. If between sizes, size up. If thigh and calf fall in different sizes, choose the larger size.

How to Apply the E-KN042 Knee Brace
- Sit on the floor and measure your thigh (5" above kneecap) and calf (4" below kneecap). Use the size chart to select your size.
- Select the correct side — Left or Right — matching your affected knee.
- Loosen all straps fully before putting on the brace.
- Open the brace and step into it, pulling it up so the patellar opening fits snugly around the lower margin of the kneecap.
- Ensure the hinge axis aligns with your knee's natural rotational axis (center of the knee joint).
- Wrap the upper sleeve and secure with the hook-and-loop closure.
- Fasten straps 1 and 2 snugly — firm compression without cutting off circulation.
Consult your healthcare provider to confirm proper fit and usage for your specific condition and anatomy.

Frequently Asked Questions
What is an OA unloader knee brace used for?
An OA unloader knee brace is used to relieve pain from medial or lateral compartment osteoarthritis by mechanically shifting the compressive load away from the damaged compartment of the knee joint. It reduces pain, slows further joint degeneration, and allows patients to remain active without surgery.
Is the eLife E-KN042 FSA or HSA eligible?
Yes. The eLife E-KN042 OA Unloader Knee Brace is eligible for purchase with FSA (Flexible Spending Account) and HSA (Health Savings Account) funds. Check with your plan administrator for specific reimbursement requirements.
How do I know if I need a left or right knee brace?
Order the side that matches your affected knee. If your left knee has osteoarthritis, order Left. If your right knee is affected, order Right. The E-KN042 is anatomically shaped for each side and they are not interchangeable.
What is the difference between an OA unloader brace and a standard knee sleeve?
A standard knee sleeve provides compression and warmth but does not offload the joint. An OA unloader brace uses a rigid dual-axis hinge system to mechanically shift load away from the damaged compartment, providing genuine pain relief for osteoarthritis patients rather than just compression.
Can I wear the eLife E-KN042 knee brace all day?
Yes. The E-KN042 is designed for all-day daily wear. The breathable, moisture-wicking fabric and adjustable straps make it suitable for extended use during work, daily activities, and light exercise. Remove and inspect the skin underneath periodically, especially during initial fitting.
Is the eLife E-KN042 good for bone on bone knee pain?
Yes. The E-KN042 OA unloader brace is commonly used for bone-on-bone knee pain caused by advanced osteoarthritis. By redistributing compressive load away from the affected compartment, it reduces the direct joint contact that causes pain, making it a non-surgical management option for severe OA.
How do I measure for the eLife E-KN042 knee brace?
Sit on the floor and measure your thigh circumference 5 inches above the top of your kneecap, and your calf circumference 4 inches below the bottom of your kneecap. Measure loosely on bare skin. If between sizes, size up. If your thigh and calf measurements fall in different sizes, choose the larger size.
