Abstract: Devices and methods for performing total knee arthroplasty procedures with kinematic alignment are described herein. A method of performing a total knee arthroplasty can comprise positioning a femoral cut guide adjacent a distal end of a femur, positioning a tibial cut guide proximate a proximal end of a tibia adjacent an anterior surface of the tibia, adjusting a position of the femoral cut guide and the tibial cut guide relative to each other using a tibial positioning device, fixing the position of the femoral cut guide relative to the tibial cut guide using the tibial positioning device, and resecting the femur and tibia with parallel resections using the femoral and tibial cut guides.

Abstract: A relaxation device includes a base, a support structure connected to the base, a seating portion and a drive mechanism. The drive mechanism is coupled to the seating portion and moves the seating portion in a manner replicating the gate of a walking horse. Persons with autism spectrum disorders and other conditions may utilize the device as a method of relaxation to lessen certain behaviors and characteristics associated with such conditions.
