The BioSkin Q Lok is the only brace that has been shown to affect patellar positioning in weight bearing MRI studies. The unique design provides necessary compression while increasing surface contact area in the joint, thereby decreasing pain. The superior compression and unique strapping system of the Q Lok push the patella back into the correct position in the trochlear notch. A properly positioned patella spreads the force in the knee joint over a larger surface and decreases pain and wear on the joint. This brace is constructed from Bio Skin’s breathable materials making it very comfortable while giving excellent compression without causing discomfort. A lightweight range-of-motion hinge controls flexion and extension without adding excess bulk and weight.
