| BACKGROUND: The growing maturity of Total Knee Arthroplasty(TKA)makes it a therapeutic tool for the treatment of various end-stage knee disorders and has achieved definite clinical efficacy.At the same time,with the aging process in China,the increasing standard of living,people pay more attention to their quality of life,coupled with the gradual popularization of artificial joints,artificial knee replacement surgery was gradually accepted,Expectations,not only limited to a simple solution to the pain,but also look forward to a more comfortable postoperative experience to meet the needs of daily life at the same time,to meet some special needs of life,such as squatting,kneeling,etc.,not only to The surgeon made a higher requirement,the knee prosthesis is also a great test,because the conventional conventional knee prosthesis,from the original design,the design of the prosthesis flexion angle of about 120 degrees,from the design The root cause can not meet the requirements,so the prosthesis designers,through the prosthesis in the clinical pain in the numerous problems,as well as a large number of biomechanical experiments,designed a new type of high flexion knee prosthesis,prosthesis In the buckling of 155 degrees when the conventional prosthesis will not appear in the face of contact,wear and other adverse factors,but the clinical efficacy of the actual efficacy is still controversial [ 1 ].OBJECTIVE: To investigate the difference in the clinical efficacy of early pregnancy after total knee arthroplasty(Nex Gex.LPS-Flex ZIMMER)and conventional flexion knee prosthesis(Vanguard PS Biomet).Methods: A total of 37 patients(11 males and 12 knees)with high flexion knee prosthesis were selected.The patients undergoing total knee arthroplasty were treated with total knee arthroplasty in the Second Affiliated Hospital of Dalian Medical University.39 knees)were divided into group A,and the general flexion knee joint prosthesis 38 were 52 knees(5 male and 6 knees,33 female 46 knees)were group B.The operation time,intraoperative blood loss,ROM activity before and after replacement were analyzed by SPSS20.0 statistical software.The femoral eccentricity(PCO)before and after replacement was analyzed before and after January,June and last After a KSS score of 2(Knee Society Score of American,the clinical score and functional score),and common clinical complications.RESULTS AND CONCLUSION: A total of 73 patients underwent postoperative follow-up.After follow-up,5 patients had delayed incision,1 had common peroneal nerve injury,2 had postoperative pain,and had poor function.No infection,prosthesis around the fracture,stiffness and other major complications.There was no significant difference between the two groups(P> 0.05).There was no significant difference between the two groups(P> 0.05).There was no significant difference between the two groups(P> 0.05)).There was a significant difference between the two groups(P <0.05).There was significant difference between the two groups(P <0.05).There was significant difference between the two groups(P <0.05)(P <0.05).The knee joint activity and KSS score of group A were better than those of B,suggesting that the use of different prosthesis artificial Knee arthroplasty,the patients have a significant effect after surgery,can improve the patient’s knee function,improve the quality of life;two groups of patients without statistical difference in intraoperative time,but the use of ordinary flexor type knee prosthesis patients Intraoperative bleeding less than the high flexion type knee prosthesis;but the use of high flexion type knee prosthesis has better knee flexion,postoperative knee function is better than the general flexion type knee prosthesis The... |
