Clinical effect of individualization anatomical reconstruction of anterior cruciate ligament

Objective To observe the clinical effect of arthroscopic individualization single bundle anterior cruciate ligament (ACL) reconstruction.Methods With the informed consents,60 cases with ACL injury who underwent arthroscopic reconstruction were selected from Henan province people' s hospital from January 2011 to September2011,all of the patients were followed up after ACL reconstructive surgery.To collect the data of knee stability,range of motion,myodynamic recovery,gait analysis,self-induction satisfaction,Lysholm score (0-100 points,higher scores indicated better functionaI recovery of knee joint),Tegner score (0-10 points,higher scores indicated better functionaI recovery of knee joint),and analyse the kinematic data.Results All of the 60 patients had been followed up for 12-18 months,average 16 months.Active range of motion,gait and quadriceps femoris strength can returned to normal in early postoperative.At the end of follow up:Lysholm scores increased from 48.4 ±8.7 to 92.2 ± 2.4 (P ＜ 0.05).Tegner scores increased from 2-4 to 6-8 (P ＜ 0.05).Conclusions Individualization anatomic ACL reconstruction seemed to best match the native femoral and tibial ACL footprint,and the function of knee joint can be obviously improved in ACL reconstruction.
