Week 7

Week 7 is the phase test week...
So, I managed to completed some part of proposal that is problem statement...
Problem statement is a short summary of the research problem....
This is the problem statement of KJT devices...
These are main reasons of why this project and research ....

1. Knee replacement, or knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve the pain and disability of osteoarthritis. Knee replacement surgery can be performed as a partial or a total knee replacement. In general, the surgery consists of replacing the diseased or damaged joint surfaces of the knee with metal and plastic components shaped to allow continued motion of the knee.

2. The anterior cruciate ligament (ACL) is a cruciate ligament which is one of the four major ligaments of the human knee. The ACL originates from deep within the notch of the distal femur. It is referred to as the cranial cruciate ligament. Athletes commonly tear the ACL when the tibia translates anterior to the femur in combination with an internal tibial rotation.

3. Cartilage structures and functions can be damaged. Such damage can result from a variety of causes, such as a bad fall or traumatic sport-accident, previous knee injuries or wear and tear over time. Immobilization for long periods can also result in cartilage damage. Articular cartilage does not usually regenerate (the process of repair by formation of the same type of tissue) after injury or disease leading to loss of tissue and formation of a defect.
