Patient: I sprained my right knee playing soccer in 2006, and have repeated the injury three times since then, most recently a year ago, and now I feel that my knee is loose and weak compared to my left knee, and sometimes when I am in a certain position, there is a sudden feeling of slippage, and there is also a “crunching” sound when I bend my knee. What kind of treatment is needed? Which is better, surgery or conservative treatment, and if surgery, how much does it cost? Orthopaedic surgery expert: According to your description and the nuclear magnetic film, we judge your diagnosis: 1, anterior and posterior cruciate ligament injury, 2, meniscus injury. Surgery is recommended, arthroscopic cruciate ligament reconstruction + meniscoplasty. Patient: I am very grateful for Dr. Jia’s answer, and I would like to ask how much is the total cost of the surgery? Orthopedic surgeon: The total cost of this surgery should be between 20-25 thousand dollars. Patient: Well, thank you very much for your warm reply! I sincerely wish the doctor good work and good health!
