The central part of the CRX Patella brace has the highest compression zone to control local swelling over the joint. This zone grades out in the two zones above and below with 30% less compression, which helps to transport the swelling to the larger muscle groups in the thigh and calf. In the upper and lower end of the brace are the third compression zones with the least compression to not trap swelling above and below. On each side of the brace are spiral stays to provide light support to the joint. 

For larger thighs there is a new option called PLUS. These sizes are available from M–XXXL and have 3 cm wider circumference over the thigh but the same circumference around the knee and calf as the standard sizes.

Indications:

Low to moderate grade ligament injuries

Patella tendonitis

Arthritic pain

General knee pain

Low to moderate instability at the knee
