Effect of remnant preservation and remove in anterior cruciate ligament reconstruction under arthroscopy

Objective: To compare the clinical effects of remnant preservation and remnant remove in anterior cruciate ligament(ACL) reconstruction under arthroscopy.Methods: The clinical data of 70 ACL rupture patients followed by 12 months were retrospectively analyzed.The observation group(35 cases) and control group(35 cases) were treated with ACL reconstruction through remnant preservation and remove,respectively.The joint stability,joint function and proprioception recovery between two groups were analyzed.Results: All patients were followed up for 12 to 27 months.The difference of joint stability between two groups was not statistically significant(P>0.05).At the end of following up,the joint function in observation group was better than that in control group(P<0.01).The proprioception in observation group was better than that in control group(P<0.01).Conclusions: The effects of remnant preservation and remove in the anterior cruciate ligament reconstruction under arthroscopy are good,and which can recover the joint stability.The remnant preservation method can more conducive to the recovery of knee joint function and proprioception.
