Arthritis is a highly prevalent disease in Beijing, with many people suffering from knee pain and hobbling, and knee arthroplasty is mainly for patients with rheumatoid arthritis and other joint damage, as well as joint pain and difficulty walking due to long-term overuse. Among these patients, the middle-aged and elderly are the “main force”, and the predominantly female population has a high incidence. The literature shows that the incidence is as high as 50-70%. Artificial knee replacement surgery not only relieves the patient of pain, but also improves joint function. However, doctors are often frustrated to see that many patients are reluctant to undergo surgery because they have concerns about it, even though they are already very ill and have difficulty walking. In fact, artificial knee replacement surgery is a very safe procedure, and the technology is so mature that many patients have been able to resume a normal life through treatment. In general, knee replacements use bone cement and are surface replacements, where the bones of the broken joint surface are cut out and replaced with an artificial surface. Also, the deformity of the knee joint can be corrected together with the surgery to restore function to normal levels. There are two types of knee artificial joint replacement prosthesis, one is solid platform prosthesis and the other is rotating platform prosthesis, each has many models to match, the width and size is measured by the surgeon on the operating table, and the suitable model can be selected for installation according to the size of the patient’s bones. Artificial joint prosthesis price Solid platform prosthesis (imported): about 24,000 yuan Rotating platform prosthesis (imported): about 30,000 yuan Hospitalization cost The cost of artificial joint replacement is generally divided into two parts: artificial joint prosthesis fee and treatment fee. Treatment costs include hospitalization, surgery and medication. Generally, the total hospitalization cost is about 40,000 – 50,000 RMB. Medical insurance reimbursement The artificial knee prosthesis can be reimbursed for $5,000, and most of the other treatment costs can be reimbursed through medical insurance.
