On the 18th, the reporter interviewed Zhang Yingze, academician of the Chinese Academy of Engineering and dean of the Third Hospital of Hebei Medical University, and learned that their innovative minimally invasive knee-protection program has been clinically treated in more than 270 hospitals, treating thousands of patients.

When I am older, why is the knee joint easy to get pain when going up and down the stairs, and it is easy to "O" shaped legs? This imbalance of joints caused by osteoporosis may eventually lead to knee osteoarthritis (KOA). The White Paper on Prevention and Treatment of Osteoarthritis in China published in 2015 pointed out that there are about 150 million people suffering from diseases in China, most of them are people with KOA disease, and with the aging of the population, the base of the incidence of knee osteoarthritis will continue to expand.
Zhang Yingze said that about 46% of the elderly in the 65-year-old population suffer from varying degrees of osteoarthritis. According to previous medical research, knee osteoarthritis is caused by the wear of articular cartilage. After anatomy, imaging, biomechanics and clinical research, they have made new progress in the etiology and minimally invasive treatment of knee osteoarthritis.
First, they introduced the mechanics principle in a series of orthopedic research, and proposed the theory of "differential subsidence" of bones. The cause of knee osteoarthritis was elucidated from the principle of bone stress.
“'Differential settlement', also known as 'uneven settlement', is a mechanical phenomenon that occurs when objects are affected by gravity and is common in nature. For example, the collapse of the road surface occasionally occurs, and the house dumps to one side.†Zhang Yingze explained It is said that human bones may also have "uneven subsidence" due to gravity. When the human bones are osteoporotic, the loose parts may have "micro-fractures" under weight and weight. When these "micro-fractures" accumulate over time, It will cause bone collapse, sinking, joint deformation and other diseases.
He further pointed out that this "uneven subsidence" phenomenon is most significant and typical at the proximal end of the spine and tibia. The inside of the tibial plateau bears 2/3 of the weight of the human body, and the lateral side of the platform bears 1/3 of the weight, and the lateral side is supported by the humerus with almost no osteoporosis. Therefore, when the skeletal bone on the inside of the platform is loose and unevenly settles, the height is lowered, lower than the outer side, and the pressure distribution is more uneven, which further aggravates the abrasion and induces knee osteoarthritis.
After clarifying the cause and process of knee osteoarthritis, experts have suggested that the minimally invasive knee-surgery operation of the humerus can restore the balance of the medial and lateral load of the tibial plateau, relieve pain, restore joint function, and avoid Joint replacement surgery.
Zhang Yingze and his team also independently developed the “Knee Balance Support Absorbable Pad†for the treatment of knee osteoarthritis. This absorbable gasket is made of a combination of type I collagen and hydroxyapatite and is a medical material approved by the Food and Drug Administration (FDA).
At present, the above research results have been prospectively studied and applied in the hospitals of the People's Liberation Army General Hospital, Shanghai Changzheng Hospital, and the First Affiliated Hospital of Dalian Medical University. According to reports, the results are also used in Japan, South Korea, Cuba, Ukraine and other countries for the treatment of knee osteoarthritis patients, doctors have said that "sacral osteotomy is a convenient new technology, for the increasingly prominent ageing The issue of clarification is important."
