Abstract
The invention relates to a polyurethane bone-tendon graft biomaterial and method of making the bone-tendon graft biomaterial. The biomaterial has a gradient of mechanical properties through photocrosslinking such that a first end of the biomaterial is crosslinked at a higher degree than a second end, and the first end of the biomaterial has mechanical properties of bone and the second end of the biomaterial has mechanical properties of tendon.
