Abstract: A knee brace spring lock and release hinge including a first section and second section. The first section has an arched support housing with a J-curved recess. The second section includes a base with base platform, an arched support surrounding a rotational wheel, a wheel pad abutting a portion of the wheel, and at least one spring extending from the base platform to the wheel pad. The second section is structured to rotate within the J-curved recess when the at least one spring is extended. The second section is structured to be locked into place when the at least one spring is compressed.
