Comparison of Therapeutic Efficacy between Arthroscopic Anterior Cruciate Ligament Reconstruction without and with Residual Preservation
Objective:To compare the clinical efficacy and biomechanical indicators of arthroscopic anterior cruciate liga-ment(ACL)reconstruction without and with residual preservation.Methods:72 patients with ACL injury from March 2022 to January 2023 were selected and divided into control group and observation group,with 36 cases in each group.The control group thoroughly cleaned the residual ligaments according to routine procedures,while the observation group per-formed a small amount of cleaning while preserving the residual ligaments.Both groups received autologous ipsilateral hamstring tendons for tendon weaving and fixation.Observe the joint function(Lysholm score,IKDC score),propriocep-tion(reproduction of passive joint range of motion at 15°,45°,and 75°),elliptical area,stride width,stride length,biphasic support,hip flexion,ankle plantar flexion angle,knee extension torque,and knee internal rotation torque of two groups of patients at 6 and 12 months post surgery.Results:The Lysholm score of the observation group was higher than that of the control group at 6 months of surgery(P＜0.05),and there was no difference in the IKDC score between the two groups(P＞0.05).The Lysholm score of the observation group was higher than that of the control group at 12 months(P＜0.05),and there was no difference in the IKDC score between the two groups(P＞0.05).The passive joint range of motion was reproduced at three angles(15°,45°,75°),and the observation group was lower than the control group(P＜0.05).Among the multiple parameters of static standing and walking,the observation group had a lower proportion of plantar pressure ellipse area and double support compared to the control group,and a higher stride than the control group(P＜0.05);There was no significant difference in step width between the two groups(P＞0.05).Among the multiple parameters of leg vertical jumping,the observation group had lower hip flexion than the control group,and greater knee extension torque than the control group(P＜0.05);However,there was no significant difference(P＞0.05)in the ankle plantar flexion and knee internal rotation torque between the two groups.Conclusion:Arthroscopic anterior cruciate liga-ment reconstruction surgery with and without residual ligament preservation can better improve joint function scores and proprioceptive ability,as well as improve biomechanical indicators in patients.
