Treatment methods
puncture mouth, knee joints
JOINT EFFUSION, INFILTRATION, CAVITY
Under a supine position, the knee joint was exposed and kept flexed at 70-90°, and the medial-lateral knee eyes were used as the puncture point. After routine disinfection and draping, the patients received infiltration anesthesia with 1% lidocaine injected layer by layer at the puncture point. The 7# puncture needle was inserted into the knee articular cavity from the puncture point, the needle cylinder was connected to draw out joint effusion, and the needle was retained, followed by articular injection of drugs. In control group, routine comprehensive therapy was performed: Glucosamine Hydrochloride Tablets (Zhejiang Chengyi Pharmaceutical Co., Ltd., NMPN H20060748) were taken once a day (1.5 g/time), and sodium hyaluronate (Shandong Bausch & Lomb Freda Pharmaceutical Co., Ltd., NMPN H10960136) was injected into the articular cavity (20 mg/time). In observation group, 30 mL of medical ozone at a concentration of 30 µg/mL was first injected into the knee articular cavity, and then the puncture mouth was covered with aseptic dressing for half an hour. Then 20 mg of sodium hyaluronate was injected into the knee articular cavity. The treatment was performed once a week for 5 consecutive weeks as one course in both groups. Patients were asked to avoid activities that damage the knee joints during treatment, such as mountain climbing and stair climbing.
