Knee osteoarthritis (KOA) is the most common disease of the sports system, with a high disability rate, and is an urgent public health problem in China at present. Through a prospective clinical study, this study took KOA patients as the research objects, and aimed to compare the efficacy and recovery of domestic 3D printed orthopedic insoles and drug conservative treatment for different degrees of KOA patients. Indicators included the tibial varus angle (TBVA), knee joint range of motion (ROM), subjective score of the International Knee Joint Literature Committee (IKDC), pain visual simulation score (VAS), and clinical effectiveness, Knee joint injury and osteoarthritis score (KOOS). The results showed that the TBVA, KOOS-symptoms, KOOS-activities of daily living, and KOOS-quality of life in the orthopedic group were significantly lower than those in the medication group, while the IKDC score was significantly higher than those in the medication group. For patients with moderate KOA, the ROM and clinical effective rate in the orthopedic group were significantly higher than those in the medication group. It showed that the efficacy and prognosis of domestic 3D printed orthopedic insoles in the treatment of moderate and severe KOA were better than that of drug conservative treatment, and its efficacy was better for patients with moderate KOA.
