The DonJoy Lateral J brace is designed to stabilize the kneecap to prevent dislocations and alleviate frontal knee pain.
The DonJoy Lateral J knee brace is a very popular patella stabilizing brace. The brace is equipped with a tubular, lateral "J" buttress that runs alongside the knee and provides support against lateral patellar subluxation, dislocations, or improper patellar tracking. The Lateral J can be worn during day-to-day activities, as well as sports and in water.
Drytex is DonJoy's exclusive solution for patients with neoprene sensitivities or those who prefer less warmth from their bracing. Constructed of a unique patented nylon core and polyester Lycra fabric, it allows for improved airflow while still giving ample support and compression. Perfect for people in warm weather climates and those with neoprene allergies or irritations.
With or Without Hinge? This brace is available with a removable hinge for added stability for an additional cost. You should order the brace with a hinge if you have joint instability. It will provide more medial and lateral support. Otherwise, you should order the brace without a hinge.

Take the measurement of your thigh and calf 6" above and below the centre of your kneecap using a flexible type tape measure. Use the diameter you measure here to choose your size.
If you have a lot of swelling in your knee, and your measurements are near the bottom of the size class, we recommend going a size smaller. Still not sure which size, call us and ask to speak to one of our physiotherapists.
