ObjectiveTo compare the clinical efficacy of the treatment of anterior cruciate ligament(ACL) injury between with and without preservation stump single bundle reconstruction under arthroscopy.

MethodsA total of 30 patients treated with ACL reconstruction under arthroscopy were randomly divided into the preservation group and unpreservation group(15 cases in each group).The preservation group and unpreservation group were treated with and without ACL reconstruction, respectively.The Lysholm score, IKDC score and Tegner score in two groups between before operation and after 6 months of surgery, and postoperative knee joint mobility and stability between two groups were compared.The propensity indicators after 6 months of operation between two groups were compared.

ResultsThere was no statistical significance in the preoperative Lysholm score, IKDC score and Tegner score between two groups(P>0.05), and the Lysholm score, IKDC score and Tegner score in preservation group after 6 months of operation were significantly higher than those in unpreservation group(P < 0.05).There was no statistical significant difference in the side-to-side difference value of KT-1000 and ROM angle in two groups between before operation and after 6 months of operation(P>0.05).The passive angle regeneration test angle and passive activity detection threshold in preservation group after 6 months of operation were lower than those in unpreservation group(P < 0.01).

ConclusionsThe preservation stump single bundle reconstruction of ACL can better promote the recovery of postoperative knee function and proprioception, and the clinical effect of which is better than that of unpreservation stump single bundle reconstruction.
