Abstract: Objective To investigate the application of suture anchors (SA) combined with bio-absorbable interference screw (BIS) for graft fixation on tibia in anterior cruciate ligament (ACL) reconstruction.Methods Seventy-six patients who were diagnosed with ACL tear for ACL reconstruction were recruited from March 2015 to May 2017 at Beijing Chaoyang Hospital. According to the principle of baseline feature matching between groups, they were divided into two groups: SA group (37 cases) and Staple group (39 cases). During surgery, Endobutton was used for cortical femoral suspensory fixation in both groups. BIS with SA were used for tibial fixation in SA group. Respectively, BIS with staples were used for tibial fixation in Staple group. Lysholm, the International Knee Documentation Committee Knee Evaluation Form (IKDC) scores, visual analogue score (VAS), range of motion (ROM) and the incidence of kneeling pain were evaluated. Anterior drawer test, Lachman test and pivot shift test were recorded. Besides, the baseline information [age, body mass index (BMI), operation time, incision length, intraoperative hemorrhage and hospitalization expenses] was also collected. Baseline information was analyzed by ANOVA. Repetitive measurement and analysis of variance was used to analyze Lysholm score, IKDC score, VAS and ROM between both groups. Results At the last follow-up, all patients, were associated with negative anterior drawer, pivot shift and Lachman tests. Lysholm, IKDC scores and range of motion were significantly better than those before surgery (P<0.05), but there was no statistical difference between the two groups (P>0.05). Besides, at 6 months after surgery, kneeling pain was performed in 8 patients in Staple group, five patients of whom were performed secondary surgery for removing staples and debridement. Relatively, kneeling pain was preformed in 1 patients in SA group. This difference was statistically significant (P<0.05). Conclusion This study demonstrates that both tibial cortical fixation, either BIS with staples or BIS with SA, achieved similar satisfactory clinical outcomes for ACL reconstruction. Besides, lower incidence of kneeling pain was performed in BIS with SA.
