Osteoarthritis of the Knee

Early stages of knee Osteoarthritis (OA) is characterised by the onset of pain and mild inflammation around the knee. Usually pain is more severe in the morning and the knee may feel stiff and take a while to loosen up.

What is Knee Osteoarthritis (OA)?

Osteoarthritis (OA) is the most common form of arthritis and is characterised by the gradual breakdown of the articular cartilage in synovial joints, primarily of the knees, hands, and hips.

What causes Knee Osteoarthritis (OA)?

The body is complex and has processes in place to repair and maintain itself. OA is a result of this process being unable to occur correctly and causes an imbalance in enzymes which leads to the loss of collagen and proteoglycans, two proteins that are essential in the composition of the body's connective tissue. It can occur spontaneously or be secondary to another condition.

What are the Risk Factors for Knee Osteoarthritis (OA)?

OA is often associated with joint wear and tear due to aging but can also stem from joint injuries, musculoskeletal abnormalities, genetics, and environmental factors. Obesity exacerbates OA by increasing joint stress and inflammation.

What are the Symptoms of Knee Osteoarthritis (OA)?

Symptoms include pain, swelling, stiffness, and reduced range of motion in the affected joint. Symptoms may worsen in cold weather, upon initiating activity, or after prolonged activity.

How is Knee Osteoarthritis (OA) Evaluated?

Practitioners diagnose OA using radiographic imaging. Key indicators of OA are narrowed joint spaces and bony spur formation which are indicative of cartilage breakdown.

What are the Treatment Options for Knee Osteoarthritis (OA)?

While there is no cure, treatment options aim to alleviate pain. Options include pharmaceuticals, physical therapy, bracing, and surgical intervention ^[1]. Treatment reccomendations will be tailored to the patietnt as well as the severity and location of the OA.

How Does Bracing Help Manage Knee Osteoarthritis (OA)?

Bracing aims to offload or stabilize the affected joint to reduce pain^[2,3]. It is often used alongside medication and can be effective for mild to severe OA. Braces will apply three forces, in a 'push' or 'pull' mechanism, to open the joint space and is primarily beneficial for unilateral OA.

BRACING OPTIONS

The amount of support provided by the brace is dictated by the severity of the OA and how active a person is. For example, an individual with very severe OA but is not very active, will not require as much support as someone with the same level of OA but is very active. This is because the person who is not as active will not be putting as much weight through the joint which can aggrevate their condition.

Mild support

Recommended for individuals with low OA severity and high activity level or vice-versa.

Action reliever Anatomically shaped knitted fabric provides medical grade compression (~25mmHg) Cross straps deliver an off-loading force that increases when the knee is straight and needs it the most Clinically proven to decrease pain upon exertion and increase walking speed when compared to non-bracing[4].
Airshift Contains an Airbladder system that can be adjusted to the level of unloading needed Re-positionable condylar gel pads focuses the air bladder’s unloading force. Alternating strap patters to prevent rotation of the brace

Moderate support

Ideal for individuals with a moderate to high activity level or OA severity.

UniReliever BOA-dial system for adjustable and precise offloading Cross straps delivers an off-loading force that increases the knee is straight and needs it the most Quick-fit buttons for easy removal and wearing
Aspen OA brace One step closure to for easy removal and wearing Easily adjustable hinge above and below the knee for comfort Comfortable non slip pads

High support

For those with severe OA or a high activity level.

Rebel Reliever Loadshifter Technology allows for adjustable corrective forces Clinically found to reduce pain during motion to promote functional ability by decreasing the detrimental forces at the knee during stance[5][6]. Available in a range of fun colours
