The knee joint joins the thigh with the leg and consists of two articulations: one between the femur and tibia, and one between the femur and patella. It is the largest joint in the human body and is very complicated.Knee is a pivotal hinge joint, which permits flexion and extension as well as a slight medial and lateral rotation. Since in humans the knee supports nearly the whole weight of the body, it is vulnerable to various
injuries. Knee is a hinge type synovial joint, which is composed of three functional compartments: the femoropatellar articulation consists of the
patella, or “kneecap”, and the patellar groove on the front of the femur through which it slides; and the medial and lateral femorotibial articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower leg. The joint is bathed in synovial fluid which is contained inside the synovial membrane called the joint capsule. The crutiate ligament is an area that has recently been the subject of renewed scrutiny and research. In this report, we focus on the patents covering knee ailments, diagnostic methods and treatments involved.Our search strategy as shown in next section highlights the same. With the help of Patent iNSIGHT Pro, we will analyze the patent data around Knee Problems to
find answers to the following:
- What does the IP publication trend for knee anatomy look like and how have the filings evolved?
- Who are the top assignees or key players in knee anatomy and what are their technology wise trends?
- How is research in knee anatomy spread across different countries?
