Description

Knee joint osteoarthritis intelligent correction instrument

technical field

The invention relates to the technical field of medical devices, in particular to an intelligent all-in-one instrument for knee osteoarthritis correction.

Background technique

Osteoarthritis is a common chronic arthritis, also known as degenerative arthritis, which is more common in the elderly over 65 years old. Among them, knee osteoarthritis accounts for about 31% of all osteoarthritis in the whole body. Osteoarthritis of the knee causes joint pain, swelling, dysfunction, and limited mobility, seriously affecting the patient's quality of life. So far there is no complete cure.

At present, the clinical treatment of osteoarthritis is mainly divided into drug therapy (anti-inflammatory and analgesic drugs to relieve clinical symptoms), rehabilitation physiotherapy (such as infrared, ultrashort wave and other physiotherapy) and artificial joint replacement. Although physical and drug therapy can alleviate the patient's pain to a certain extent, they cannot fundamentally improve the deformity line of the knee joint. Surgical treatment is not only traumatic and expensive, but also requires high technology. It is only suitable for patients with advanced knee osteoarthritis and is difficult to be accepted by most patients.

The root cause of the exacerbation of knee osteoarthritis is the inflammation that has not been completely eliminated and the unreasonable distribution of internal stress in the knee joint, that is, the deformity of the force line. At the same time, incorrect gait will also cause the deformity of the internal force line of the knee joint and accelerate the wear and tear of the cartilage side of the knee joint. Therefore, for patients with knee osteoarthritis, the measures to delay osteoarthritis, on the one hand, should reduce the load on the knee joint, and on the other hand, it is necessary to correct the line of force of the lower limbs and reduce the length of the moment arm of varus and varus. Therefore, orthotics or walking aids are gradually accepted by the majority of patients.

The orthotics currently used clinically have a single function, have no drug and physical therapy effects, and cannot dynamically reduce the load. In addition, in actual use, it takes a lot of time and effort to wear a suitable orthosis. Through the detection and adjustment of external forces, it is impossible to know in time when the patient's condition worsens.
