In general, after knee joint surgery, rehabilitation treatment for the knee joint is started through rehabilitation exercise of the knee joint. The typical goals of rehabilitation are 'strengthening muscle strength' and 'restoring joint range of motion'.

For example, in degenerative arthritis rehabilitation subjects, muscle strength in the knee region is weakened before surgery due to pain, and knee muscle strength is further weakened due to pain and swelling after surgery. Therefore, after knee joint surgery, it is desirable to not only reduce pain while strengthening the knee muscle through rehabilitation treatment, but also recover movement and muscle strength of the knee joint more quickly than before surgery. As the circulation of the lower extremities is promoted through the rehabilitation treatment as described above, it is possible to prevent thrombosis, which is one of the main sequelae.

On the other hand, rehabilitation treatment of the knee joint is divided into rehabilitation exercise treatment and non-exercise physical therapy. Among them, rehabilitation exercise treatment includes joint motion range improvement training to increase the joint range of motion, muscle strength training using knee joint exercise equipment such as elastic rubber bands or slings, walking training, balance training, and the like.

In general, it is more effective for rehabilitation subjects to perform rehabilitation exercises using a knee rehabilitation training device. By the way, the existing knee rehabilitation training apparatus can perform various joint movements, but has the disadvantages that the equipment is large, complex, heavy, and expensive. In addition, since the existing knee rehabilitation training apparatus is designed and designed for physically healthy people such as athletes, there are many cases where it is not suitable for use by surgery patients, the elderly, and children.

Therefore, in recent years, research and development of a knee rehabilitation training device having a simple overall structure, low manufacturing cost, and user convenience for surgical patients, the elderly, and children has been developed.
