Orthotic
A custom or prefabricated device worn to support, align, or correct joint and limb function. For knee arthritis, includes braces, shoe inserts, and wedged insoles that reduce joint stress.
Extended Definition
Orthotics are external devices that support or correct musculoskeletal function. For joint pain, they can redistribute weight, improve alignment, and reduce stress on damaged areas.
Types for Joint Pain
Knee Orthotics:
- Unloader braces - Shift weight off damaged compartment
- Sleeve supports - Provide compression and warmth
- Hinged braces - Add stability
Foot Orthotics:
- Lateral wedge insoles - For medial knee OA
- Custom orthotics - Correct foot/ankle alignment
- Shoe modifications - Rocker soles, cushioning
Unloader Braces for Knee OA
For unicompartmental knee OA:
- Applies force to “unload” the affected side
- Reduces bone-on-bone contact
- Can reduce pain 30-50%
- Works best for medial compartment OA
Considerations:
- Requires proper fitting
- Takes time to adjust
- May be bulky under clothing
- Must be worn consistently
Insurance Coverage
Medicare covers:
- Custom knee braces (with diagnosis/prescription)
- Diabetic shoes/inserts
- Some prefabricated braces
Typically NOT covered:
- Over-the-counter insoles
- “Wellness” orthotics
- Shoe modifications
Effectiveness
Research shows orthotics can:
- Reduce pain during activity
- Improve walking distance
- Delay need for surgery
- Work alongside other treatments
Best results when:
- Properly fitted by professional
- Used consistently
- Combined with exercise program
- Appropriate for your OA pattern

View allCorticosteroid
A powerful anti-inflammatory medication similar to cortisol (a hormone naturally produced by the body) that can be injected into joints to quickly reduce swelling and pain.
Hyaluronic Acid
A naturally occurring substance found in synovial fluid that gives it its thick, gel-like consistency and lubricating properties. Also used as an injection treatment for joint pain.
Molecular Weight
The size of a molecule measured in daltons. In hyaluronic acid products, molecular weight affects how thick and long-lasting the injection is, with higher molecular weight typically providing longer relief.
NSAID
Non-Steroidal Anti-Inflammatory Drug - a type of medication that reduces pain, inflammation, and fever by blocking enzymes that produce inflammatory chemicals in the body.
Nerve Block
An injection of anesthetic near specific nerves to temporarily block pain signals. Used for diagnosis, pain relief, or before surgery. Effects last hours to months depending on medication used.
