What is an arthroscope? Arthroscopy consists of an optical system, optical fibers and a metal sheath. Through a 0.5 cm incision, a metal tube with an illuminated lens is inserted into the joint cavity, and the image is magnified on a monitor inside the joint to observe the lesion inside the joint, so it is more accurate than the naked eye after the joint is cut open, while from another small incision hole, instruments for examination or surgery are inserted and a full The examination and surgery are performed under television surveillance. Arthroscopy is more comprehensive than an incision because almost all parts of the joint can be seen; it is more accurate than an incision because the images are magnified; and it allows medical personnel to examine the joint and perform various surgical operations under direct vision. It has the advantages of small incision, less trauma, less scarring, faster recovery and fewer complications. How is arthroscopic surgery performed for diagnosis and treatment? The arthroscope is inserted into the joint cavity through a tiny incision (about 0.5cm) on the body surface, and the image inside the joint is displayed directly on the TV screen through the camera system connected to the arthroscope, which means that the doctor can see the condition inside the patient’s joint directly through the TV screen, and therefore can make a completely correct diagnosis. At the same time, the arthroscope can be inserted into the joint through another small incision (about 0.5 cm) equipped with a state-of-the-art electric operating system, and the operation of cutting, trimming and grinding, and planing can be performed under the direct supervision of the arthroscope for the purpose of treatment. What joint injuries and diseases can be diagnosed and treated by arthroscopic surgery? It can be used for the diagnosis and treatment of meniscal injury of the knee joint and discoid cartilage of the knee joint; treatment of osteoarthritis and osteophytes of the knee joint; removal of free bodies from the knee joint; treatment of chronic synovitis; treatment of chondromalacia patellae; diagnosis and treatment of intra-articular fracture of the knee joint and anterior and posterior cruciate ligament injury of the knee joint; exfoliative osteochondritis; rheumatoid arthritis and rheumatoid arthritis; septic arthritis; joint Treatment of nodules, etc. How does arthroscopic surgery differ from conventional surgery? What are the advantages? The most important feature of arthroscopic surgery is the minimal trauma and quick recovery after surgery. Common knee surgery is very traumatic and patients need to be bedridden for 2-3 weeks after surgery before they can gradually practice their activities, and permanent scars will remain on the knee after surgery. In contrast, arthroscopic surgery requires only a tiny 0.5 cm incision, with a diagnostic accuracy rate of 98%, and can complete meniscal repair treatment that cannot be done with conventional surgery. The newly introduced German AESCULAP arthroscope worth 500,000 Yuan RMB in the Department of Orthopedics of Tangdu Hospital is extremely advanced and advanced medical equipment, which has brought the level of treatment of joint injuries and diseases to a new level. How do the joints in our body actually cooperate with our movement when we are active? The knee joint is always susceptible to damage during sports, accounting for almost 65% of sports injuries, so why is this? Because the knee joint of the leg carries more than 80% of the body’s weight and is an important part of our balance system. Experimental data shows that when walking, the weight on the cartilage surface of the knee joint is about three times the body’s own weight, and when walking up stairs, the weight on the knee joint rises to four times the value. When running, the weight on the knee joint will increase with the short and vigorous pace, and the weight index will rise significantly at this time. If the usual knee movement is too much, the weight on the joint will greatly increase, it is easy to produce a sudden jam in the knee joint, the pain is unbearable.
