Abstract
Purpose
For patients with anterior cruciate ligament (ACL) rupture, A/S ACL reconstruction can be reliable treatment for stability restoration and functional improvement. The clinical outcomes after ACL reconstruction are dependent on the restore both the anteroposterior and rotational stability observed in normal knee. The purpose of this study was to analyze patient-reported outcome measures after A/S ACL reconstruction affected by additional anterolateral ligement (ALL) recontruction using propensity score matching(PSM) analysis with an average of 2-years follow-up.
Methods
Retrospectively, we reviewed the records of 2000 knees from January 2008 to December 2013. The patients who underwent A/S ACL reconstruction for ACL rupture and a minimum follow-up of 1 year were included. 44 knees, A/S ACL reconstruction with ALL reconsruction at initial surgery (group A); 150 knees, A/S ACL reconstruction without ALL recontruction were included in the study (group B). For comparison of both group, we equalized the baseline prognostic factors of the two groups by using PSM. The propensity score was based on the following baseline covariates: age, gender, body-mass-index (BMI), Laxity test (Pivot shift test, Lachmann test), MCL injury Hx and preoperative range of motion(ROM). Clinical outcomes were also assessed including Lysholm knee score, range of motion, Tegner activity scale, associated meniscal or chondral injuries, and laxity test at preoperatively and postoperatively at the final follow-up.
Results
PSM yielded 44 pairs of patients. Age, gender, body-mass-index (BMI), Laxity test, MCL injury Hx, meniscus tear, and preoperative range of motion(ROM) in knee were shown to be similar between two groups. This study showed no significant differences in clinicoradiologic outcomes between additional ALL reconstruction group and only ACL reconstruction group except tegner activity. We also could not find any differences in flexion contracture and maximal flexion. However, the stabilities regarding Lachman and pivot-shit tests shown significant differences between two groups.
Conclusion
ALL recontruction in A/S ACL recontruction was shown to affect patient-reported clinical outcome measures in short-term follow-up without significant difference. Additional ALL recontruction was showed better anterior stability than without ALL reconstruction in A/S ACL reconstruction. long term follow up studies are needed to evaluate survivorship of ACL recontruction and determine the correlation between ALL recontrucction and anterior stability.
