Medical-grade osteoarthritis knee support designed for all-day pain relief and joint stability. The eLife E-KN042 OA Unloader Knee Brace uses a dual-axis hinge system to redistribute compressive load away from the damaged compartment of the knee — reducing pain, improving mobility, and letting you stay active through daily life, work, and rehabilitation.
Available in Small, Medium, Large, and X-Large, for both left and right knees.
Measure the circumference of your thigh and calf to select the correct size. Sit down on the floor, measure thigh 5" above the top of your kneecap, and calf 4" below the bottom of your kneecap. Measure loosely on bare skin. If between sizes, size up. If thigh and calf fall in different sizes, choose the larger size.

| Size | Thigh (in) | Thigh (cm) | Calf (in) | Calf (cm) |
|---|---|---|---|---|
| S | 11-3/4" – 14-1/2" | 30 – 37 | 9-3/4" – 11-3/4" | 25 – 30 |
| M | 14-1/2" – 17-1/4" | 37 – 44 | 11-3/4" – 13-3/4" | 30 – 35 |
| L | 17-1/4" – 20-1/2" | 44 – 52 | 13-3/4" – 16-1/2" | 35 – 42 |
| XL | 20-1/2" – 23-3/4" | 52 – 60 | 16-1/2" – 19-3/4" | 42 – 50 |
Consult your healthcare provider to confirm proper fit and usage for your specific condition and anatomy.

The E-KN042 is one of several knee support options we carry for osteoarthritis, ligament injuries, and post-operative recovery.
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.
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.
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.
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.
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.
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.
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.
