Design and Development of Post Knee Arthroscopy Assist Device

Designing and developing a device which provides a solution for knee spasms for the people who underwent surgery in the knee due to injury by enhancing the ability of motion in the knee joint and also strengthening the weak muscles. After operative procedures the patient remains in bed rest which results in passiveness in the lower limb and Range of Motion (ROM) will be reduced due to the impact of the injury. Thus, the Continuous Passive Motion (CPM) device is designed to lessen edema and swelling of the knee followed by injuries or surgeries. This device replaces the all time presence of physiotherapist and can accomplish such routine physical movements without the guidance and assistance of physiotherapist. The key feature in constructing a CPM is in the establishment of an accurate alignment with the human knee joint enabling the device to deliver similar movements as the actual body. Emergency switch is employed to the patients and they can stop the system in case of emergency or discomfort. This system comprises of Mechanical and Electronic components to full fill the necessity of the device requirements.
