[Abstract]:Background our country has entered an aging society. The patients with osteoarthritis of the knee joint are increasing year by year, and nearly 50 million people. With the continuous development of biomedicine, material engineering and surgical technique, Total knee arthroplasty (TKA) has become an important means of advanced knee osteoarthritis in the treatment of advanced knee joint. As an important structure of the knee joint, it plays an important and stable role in the flexion, extension and rotation of the knee joint. With the development of modern knee replacement technology, the reserved knee prosthesis (CR type prosthesis) and the post stable knee joint prosthesis (PS type prosthesis) have become the main two types of prosthesis design and use in the long term clinical treatment and the development of the knee joint replacement technique. In the course of academic discussion, how to choose the prosthesis has always been a long argument for the scholars. Whether the posterior cruciate ligament is retained completely during the operation is an important prerequisite for the function of the CR prosthesis after the operation. Most of the doctors in the domestic Department of orthopedics choose PS TKA for the treatment of osteoarthritis of the knee joint. In recent years, the CR type TKA has gradually increased, and the CR TKA is suitable for the people of the country. The physiological and anatomical characteristics of the knee joint and the feasibility of retaining the PCL in Chinese TKA have become the focus of this study. 1, in the study of Chinese human PS TKA, the influence factors of the residual amount of PCL and its residual amount remained after the tibial plateau was 0 degrees and the thickness of 9mm was cut, and the influence factors of the PCL residues in the PS type TKA of the Chinese people were discussed. 2, to explore the TKA CR TKA. The feasibility, technical essentials in the operation, and comparison of the clinical effect of CR type TKA and PS type TKA. Method 1, 36 cases of total knee arthroplasty in the Department of orthopedics, Xinqiao Hospital Affiliated to Third Military Medical University from May 2015 to August 2016 were selected, all were single knee patients, the age range was 52 years old -75 years, height 145cm-173cm, male and female 18. All the patients signed this research agreement and the surgical consent. The patient's height, sex, PCL retention ratio, the tibial plateau anterior and posterior diameter, the internal and external diameter, the length of the tibia were collected, and the tibial plateau specimens were collected carefully to measure the.PCL retention ratio: the tibial plateau osteotomy and the residual posterior cruciate ligament The specimens were fixed, decalcified, and the tendon bone interface was sliced and stained, and the PCL retention ratio was analyzed by Auto CAD2014 software. In May 2015 -2016 May, 16 patients received unilateral PS total knee replacement, including 16 knees, 9 women, 7 men, 55-75 years old and 65.1 years old. 16 cases, including 16 knees, 11 women, 5 men, 58-73 years old, average 65 years old. All the patients signed this study and the operation consent book.PS TKA to take routine operation. This study of CR type TKA operation essentials: after the early stage of the PS TKA tibial plateau osteotomy after the study of PCL residues, found the vast part In the patients with type CR TKA, the tibial plateau was tilting 0 degrees, 9mm osteotomy, and PCL could not be retained completely. Therefore, in the CR TKA, this study adopted the reservation of PCL bone island (with Kirschner needle on the periphery of the bone island) and the sub osteotomy (the osteotomy of the bone and the anterior and outer sides of the bone island). During this process, the PCL was kept in a relaxed state to avoid producing bone. After the island fracture and the tibial plateau osteotomy, the femoral condyle osteotomy was routinely carried out. After using the self-made tool to detect the balance of the knee joint and extension space, the prosthesis was installed, which could effectively reduce the incidence of bone island fracture caused by the flexion and extension clearance. The VAS score, the AKS score, the WOMAC score, the knee joint activity (ROM), and the femoral condyle roll distance were compared with PS The clinical efficacy of type TKA and type CR TKA after operation. Results 1, height is the influence of the internal and external diameter of tibial plateau, the size of the anterior and posterior diameter, the retention ratio of the posterior cruciate ligament, the main factor of the length of the tibia, and the proportion of the internal and external diameter of the tibial plateau, the back and back diameter, the posterior cruciate ligament, the length of the tibia, and the small influence of the tibia length, the height, and the tibial plateau diameter, the tibial plateau, and the diameter of the tibial plateau. There is a linear relationship between the diameter of the internal and external diameter, the length of tibia and the ratio of PCL residue, which shows a positive correlation. This study shows that in TKA, when the tibial plateau is 0 degrees back, and when the 9mm osteotomy is lower than 171cm, the retention ratio of PCL is below 50%, and it is generally low.2. In this study, the PCL bone island (Kirschner pin is used to take the bone island around the bone island). 0 degree posterior tibial plateau tilting, 9mm osteotomy, 2 cases of bone island avulsion fracture, changed into PS type prosthesis, and the remaining 14 cases of CR TKA patients at ROM and femoral condyle roll distance, VAS score was obviously superior to PS type TKA patients in the other 14 cases. 3 months after operation, there was no significant difference in AKS score, WOMAC score, VAS score and ROM in the patients with type CR TKA and PS TKA. Conclusion the height of the tibial plateau is influenced by the internal and external diameter of the tibial plateau, the size of the posterior cruciate ligament, the main factor of the length of the tibia, and the gender of the tibial plateau. Internal and external diameter, front and back diameter, posterior cruciate ligament retention ratio, tibial length has no influence or small impact. Height, tibial plateau diameter, internal and external diameter, the length of tibia and PCL residual ratio has a linear relationship, and there is a positive correlation. This study shows that people with height below 171cm, when the tibial plateau is 0 degrees back, 9mm osteotomy, PCL retention ratio The cases are below 50%, generally low and the residual PCL can not perform normal physiological function after operation. For most of the people who do TKA, the height is generally below 170cm. If the posterior cruciate ligament is reserved for the reserved TKA prosthesis, the operation difficulty, the technical and time requirements are increased, the risk of bone island avulsion fracture is increased in the operation, and the posterior cruciate ligament has a successful rate drop. In this study, the PCL bone island was reserved (with Kirschner's needle on the periphery of bone island) and sub osteotomy (partial osteotomy of the lateral and anterior side of the bone island). During the operation, the PCL was kept in a relaxed state, and the balance of the flexion and extension gap of the knee joint could be effectively reduced repeatedly by using the self-made tool in this study. The incidence of bone island fracture caused by the flexion and extension gap was measured with a test model. Although the CR TKA patients were at ROM and the femoral condyle roll distance on the 3 day after operation, the VAS score was obviously better than that of the PS TKA patients (P0.05). The satisfaction rate of the patients was improved, the recovery cycle was significantly shortened. However, 3 months after the operation, CR type TKA and PS TKA were scored in AKS score There is no significant difference in ROM (P0.05). Therefore, in view of the height of the majority of the people in TKA is generally below 170cm, the tibial plateau is 0 degrees behind, and when the 9mm osteotomy is taken, the PCL is successfully retained, the operation difficulty and the technical requirement are high, the operation time is increased, the bone island avulsion is easy to take place, the posterior cruciate ligament is failed, and the two types of prosthesis are made. After TKA, there was no significant difference in long-term efficacy (P0.05). Most Chinese OA patients were not suitable for CR TKA.
