Ms. Liu, 22, was sent to Hubei Zhongshan Hospital by emergency vehicles after a car accident caused serious injuries to her legs. Upon examination, she had a meniscus injury to her left knee. Ms. Liu thought that the surgery would involve a large incision and would leave an unsightly scar on her leg, and felt that it would be more painful than the physical trauma she had suffered. I told her that an arthroscopic meniscus repair with an arthroscope would only leave two small incisions of 0.5 cm and would not leave a large scar. She was relieved and went into the operating room with confidence. The surgery was completed in about an hour, and Ms. Liu was happy to see that the meniscus had completely healed and no scars were visible at the surgery site when she came back to the hospital a month later. The meniscus is a spacer between the joints that reduces the wear and tear between the knee joints and acts as a cushion and stabilizer. Without the meniscus, there would be direct friction between the bones. Therefore, after removal of the meniscus, many patients report pain between the joints when they move, which is an unavoidable disadvantage of conventional surgery. Arthroscopic meniscal suture repair, on the other hand, preserves the function of the meniscus and allows it to continue to function, which is of greater significance to many young people who experience sports injuries. Keeping pace with the development of medical technology, our orthopedic department has adopted minimally invasive orthopedic techniques and has made great progress in the treatment of spine, joint and trauma diseases, winning the trust of more and more patients due to smaller surgical incisions, lighter systemic reactions, less scar healing, shorter recovery time and better psychological effects.
