Osteoarthritis Braces

OsteoarthritisOsteoarthritis (OA), also called degenerative joint disease, is the break down of cartilage in the knee joint. As one grows older, the wear and tear of daily living and activity slowly wear out the joint. Knee trauma, such as broken bone, cartilage and/or supportive ligaments, can disrupt the integrity of the joint, leading to premature OA.

Symptoms can include a low grade ache and/or swelling, and become worse as the joint is used throughout the day.

OA is treated with knee braces as discussed above with medial/Lateral instability

Brace samples are as follows:

Post Op and ROM Braces

Generally prescribed post-operative or post-trauma.  This type of brace is designed to help support the knee as well as limit the range of motion (ROM) to whatever angles the doctor specifies.

Static-Progressive Stretch

Static progressive stretch (SPS) orthoses (braces) are used to restore lost range of motion to contracted joints through the biomechanical principle of stress relaxation. Soft tissues respond as a viscoelastic material. Soft tissues include tendons, ligaments, muscles, joint capsules, skin and fascia. As a viscoelastic material is stretched and then held at a constant length, the stress or tendency to rebound gradually declines. This decline in force is called stress relaxation. SPS used to stretch soft tissue uses a series of incremental changes in the joint position held constant over prescribed periods of time. Connective tissue responds favorably to this low-load prolonged stretch. This desired response allows the tissue to slowly adapt to the elongated length, resulting in permanent plastic deformation in the most time efficient manner.

Patient Application Instructions: Knee

1. Turn knobs (A) so the angle of the brace is the same as the leg. The leg should be in the most extended position.
2. The knee cap should be positioned between the two middle straps, with the brace on the front of the leg. Pull the straps (B) across the back of the leg and through the buckle. Straps should be secure and snug.
3. Turn the knobs together in the direction to straighten the knee until the patient experiences mild discomfort or a feeling of stretch. This feeling should reduce in less than 30 minutes. Follow prescribing physician’s instructions for length of wear, and specific knob adjustment.


Mackie Hinge braceThe Mackie Hinge Knee Brace was developed on the basis of our success with the Mackie Hinge Elbow Brace. The Mackie Hinge Knee Brace uses a unique rotating hinge mounted on a rigid, non-contact frame. This design offers simplicity of function, strong construction, and superior patient comfort. The Mackie hinge mechanism is engineered to allow for smooth and infinite positional settings. Because human physiology varies greatly from individual to individual, the hinge adjustability allows the patient to control how much force is applied to achieve the best result. For this patient-directed approach to be successful, patient tolerance and compliance is crucial. Static-Progressive Stretch is a proven concept for effective and permanent gain in range of motion.

The Mackie Hinge Knee Brace also has the ability to be used in both flexion and extension. This can avoid the added expense of a second brace because many patients require stretch in both directions. It also helps reduce the risk that range of motion might be lost in the opposite direction. Patient Application Instructions are easy to understand. Physician prescribed Wearing Protocols allow the patient to incrementally stretch the joint to tolerance by turning the knobs to increase range of motion in either flexion or extension. The Mackie Hinge Knee Brace can be used with a variety of wearing protocols, that may be customized based on physician preference and patient need. Always follow your physicians instructions if they are different from our suggestions.
