Comparation Of Medial Collateral Ligament Proximal Transfer And Medial Collateral Ligament Reconstruction To Treat Chronic Knee Medial Laxity

Objectives To investigate and contrastive analysis the clinical efficacy of medial collateral ligament proximal transfer and medial collateral ligament reconstruction to treat chronic knee medial laxity,provide the reference for clinical treatment of chronic knee medial laxity.Methods From Jan 2010 to Jan 2015,64 patients with chronic knee medial laxity who were admitted by the Orthopedic Hospital Affiliated to North China University of Science and Technology(The Second Hospital of Tangshan)were devided into the transfer group(31 cases)and reconstruction group(33 cases)according to different surgical methods.The transfer group was treated with medial collateral ligament proximal transfer,and the reconstruction group was treated with medial collateral ligament reconstruction.The function of knee was evaluated by the International K nee Documentation Committee(IKDC)score,Lysholm score and Tegner score respectively before operation and 18 months after operation.The stability of knee was evaluated by medial joint opening and joint space angle(JS)respectively before operation and 18 months after operation.The clinical efficacy of two groups was evaluated by the "C linical evaluation of the medial collateral ligament of the knee" 18 months after operation.Results There were no statistically significant d ifferences in cases,age,gender,disease duration and surgical side between 2 groups(P>0.05).All patients achieved primary incision healing without acute postoperative complications of incision infection and deep vein thrombosis in the lower limb.The patients were followed up 19-24 months(mean,21.05±1.55 months)in the transfer group,and 18-23 months(mean,20.95±1.47 months)in the reconstruction group.No knee stiffness,reinjury and knee joint infection occured in all patients.There were no significantly differences in IKDC score,Lysholm score,Tegner score,VAS score,medial joint opening and JS between two groups(P>0.05).Compared with preoperation,IK DC score,Lysholm score,Tegner score,VAS score,medial joint opening and JS of patients were significantly improved in two groups 18 months after operation(P<0.05).At 18 months after operation,IKDC score,Lysholm score,Tegner score and the rate of excellent clinical efficacy of reconstruction group were higher than that of transfer group(P<0.05).At 18 months after operation,the medial joint opening and JS of reconstruction group were lower than that of transfer group(P<0.05),but there was no significantly difference in VAS score between two groups(P>0.05).Conclusions 1 Chronic knee medial laxity could be treated effectively by both medial collateral ligament proximal transfer and medial collateral ligament reconstruction.2 Medial collateral ligament reconstruction was superior to medial collateral ligament proximal transfer in improving knee function,knee stability and clinical efficacy.However,There was no significantly difference in relieving medial knee pain between two kinds of operation method.
