Abstract
As human lifespan increases and the proportion of obese people increases, the prevalence of knee osteoarthritis continues to increase. Its main clinical manifestations include joint pain, snapping, and decreased joint function. Due to the slow progression of the disease in KOA, patients have been troubled by the disease for a long time, affecting their quality of life. Therefore, the main purpose of treatment is to relieve symptoms and restore joint function. At present, most clinical studies focus on the joint function of postoperative KOA patients. However, in real life, there are still KOA patients who do not meet the surgical standards, and there are relatively few studies on this part. Therefore, this article reviews the relevant concepts, influencing factors and intervention measures for joint function in patients with non-surgical knee osteoarthritis in recent years, to provide a theoretical reference for subsequent research on improving joint function in patients with non-surgical knee osteoarthritis, and to improve patient's quality of life.
