The orthopaedic splints 1R is the innovative solution with flexion and extension adjustment. The drop lock is very small (diameter: 30 mm) and provides 15° ROM adjustment. In addition, we apply the allen screws, which are mounted by steel pins and magnet. The most innovative is the blocking disk with the ratchet, which ensures required angle of ROM. In the short knee braces the splints 1R are universal, so they fit for both legs, but in the long knee braces the splints 1R have anatomic shape for right or left leg.
