Osteoarthritis (OA) is the most common form of joint disease, and its impact is set to grow as the prevalence of obesity rises and our elderly population increases. As a result of this disease, it is necessary to make structural examinations for the determination of the deformations that occur. One of the methods used for structural analysis of biological samples is the wide-angle X-Ray scattering (WAXS) device. In this study, hip bone samples taken from humans during surgery were investigated using wide-angle X-ray scattering technique. Hip bone specimens were primarily compared based on regional density and later on based on sex. As a result of scatter patterns, the presence of crystal structures has been determined. The values of crystal structure obtained depending on low and high dense region and sex are different.As a result of gender related comparisons, it was found that crystal structures were better in males than females.

This paper presents optimization and control of a new fully Powered Above Knee Prosthesis (PAKP) that can perform a single axis movement in the knee joint and two axes movements in the ankle joint. The knee and ankle joints are controlled by using DC servo motors. As can be a well-known issue that the weight of the prostheses can directly affect the performance of the whole system. Therefore, PAKP is produced by using PLA material due to its lighter weight. The weight of the prosthesis is also optimized for improving the performance of the system. In this study, PAKP is considered a 3-DOF serial robotic manipulator and gait cycles are treated as robotic trajectories. Finally, PAKP is controlled by applying a trajectory generation algorithm.
