Knee fluoroscopy

Selecting an appropriate method when describing the motion of the knee in 3D space can be challenging as there is no universal or standard definition currently utilised in biomechanical studies. The Joint Coordinate System (JCS), first proposed by Grood and Suntay, is widely used by various authors to define the relative position between two rigid bodies as the definitions when establishing the system is easily comprehended. Throughout this thesis, a program will be developed in Matlab to enable the automation of the joint coordinate system on the femur and tibia by defining the anatomical landmarks. The JCS will be redefined and used as a basis to implement a slightly different coordinate system. This automated program will allow simplicity when manipulating the orientation and will enable the data to be presented in different clinical systems.
