ABSTRACT
Objective To evaluate arthroscopic PCL (posterior cruciate ligament) reconstruction with an implant fixaliun of hamstring tendon knot and bottle-neck technique.Methods Thirteen cases with PCL injury were treated with arthroscopic PCL reconstruction with an implant fixation of hamstring tendon knot and bottle-neck technique between April,2002 to June,2005.The patients were followed up fur at least seven months to evaluate the clinical effects by means of ROM of the joint,post drawer test,Lachman test,Lysholm and IKDC (International Knee Documents Committee) scores.Results The patients were followed up for an average of 13.4 months.No limitation of knee extension was found six months after operation.Eleven patients had normal knee flexion(＞140?), one had knee flexion of 120?and one 100?.In posterior drawer test,11 patients were gradeⅠand two gradeⅡ.In Lachman test,11 patients were rated as within gradeⅠand two gradeⅡ.By Lysholm knee function scale,the average knee scores were 90.47?4.13 and 78.82?2.46 respectively before and after operation,and the dif- ference was of statistical significance (t=2.416,P=0.029).By IKDC scale,six were grade A,five grade B and one grade C.Conclusion Arthroseopic PCL reconstruction with an implant fixation of hamstring tendon knot and bottle-neck technique is a reliable method to restore knee function and will have a prospect of wide application be- cause of its good tissue biocompatibility,less invasion,and less operative expenditure.
