Background

Osteoarthritis is a chronic joint disease which is easy to be suffered by middle-aged and elderly people clinically, is frequently caused by weight bearing and multiple moving joints and is mainly caused by degeneration of articular cartilage. As a chronic degenerative disease, articular cartilage wear deformation and hyperosteogeny are the main characteristics of osteoarthritis. Osteoarthritis is one of the leading causes of decreased health levels in the middle aged and elderly and motor disability of the lower extremities in recent years.

Of the many osteoarticular diseases, hip arthritis and knee arthritis are the most common and frequent types of osteoarthritis, but knee osteoarthritis is more prevalent. The knee joint is one of the most important bearing and moving joints of the human body, has a complex structure and multiple functions, and is characterized by large moving amount and heavy load in daily activities, so that the damage probability of the knee joint is at the head of each joint. The knee joint plays an important role in human daily life as a main weight-bearing and moving joint. The occurrence and development of knee osteoarthritis seriously affect the quality of life of patients, and have become a serious social burden due to the characteristics of long influence time, high treatment cost and high disability rate.

On the basis of a Chinese granted patent CN215821304U with a patent name of a knee joint orthosis with a flexible application connecting structure, the stretching structure of the knee joint orthosis is realized by an extension plate which is a telescopic plate and comprises a U-shaped first plate and a second plate inserted with the first plate. The middle position is equipped with a length adjustment pole on the first plate, be equipped with on the second plate with length adjustment pole complex length adjustment cover, the length adjustment cover is prismatic structure to convenient the rotation, be equipped with the screw thread on the body of rod of length adjustment pole, the length adjustment cover rotates with the second plate and links to each other, is equipped with on it with length adjustment pole complex internal thread. Through rotating the length adjustment cover, can make it take place the action with the length adjustment pole, can move about from top to bottom along the length adjustment pole, and then realize the adjustment of the length of extension plate to satisfy user's demand, because the length adjustment cover is prismatic structure, or through rotating the length adjustment cover lateral wall, or insert the hole of length adjustment cover lateral wall with axle type pole, come the rotation length adjustment cover, the patchhole then needs to be changed at every half a turn, it is very difficult to adjust. And because the length adjustment sleeve is exposed outside the orthosis, friction rotation is easily caused in daily life, and the length of the telescopic plate is influenced.

To this end, a knee orthosis is proposed which is easy to adjust.
