Research Progress Of Multimodal Analgesia For Total Knee Arthroplasty

With the improvement of people's living standard,the level of science and technology continues to progress and development,medical technology level also will continue to improve.With the increase of average life expectancy,the aging population has gradually increased,When people age increases,the bone disease caused by degeneration will gradually increase.Osteoarthritis and rheumatoid arthritis are the most common causes of pain and discomfort in the knee joint.According to the statistics,china have owned tens of millions of people above two kinds of diseases.It has a serious impact on people's quality of life.For this kind of situation,traditional conservative drug therapy can not fundamentally solve the impact of knee pain on the quality of life.There are often many adverse reactions in drug therapy.Total knee arthroplasty is one of the methods to repair the knee joint function and relieve the pain of the knee joint.With the continuous improvement of surgical techniques,the design of the knee prosthesis is also gradually improved recentlly.The survival rate of 10 years after total knee arthroplasty was greater than 94%.The United States about 400 thousand people to take the total knee replacement each year.Their success rate was 90% to 85%.Total knee replacement has become a safe and effective treatment fo the people who are severely affected by the pain of the knee joint.But total knee arthroplasty is different from other department of orthopedics operation.Total knee replacement is often accompanied by severe postoperative pain.About 60% of the patients had severe pain,about 30% of the patients had moderate pain.Such a huge trauma and postoperative pain to bring a lot of trouble and confusion for patients.It is not uncommon the surgical effect is not good caused by Severe pain after surgery.Total knee arthroplasty not only brings pain to patients,but also affects the function of each system in varying degrees,Including circulation,respiration,digestion,endocrine and immunity.It may lead to complications after total knee arthroplasty,affect the patients after the operation of the successful rehabilitation,to extend the patient's hospital stay.Reasonable and effective analgesia can not only alleviate the pain caused by pain,but also can reduce,prevent the body to stimulate the pain of a series of stress response caused by the dysfunction of the system organs.Therefore,pain management after total knee arthroplasty has been the focus of attention of clinicians.The research on how to take effective postoperative analgesia has become one of the key points of the surgical treatment plan.This paper introduces the recent newest research progress to the mechanism of pain after total knee arthroplasty and the multimodal analgesia after total knee arthroplasty.
