Background The intent of double-bundle anterior cruciate ligament reconstruction is to reproduce the normal anterior cruciate ligament anatomy and improve knee joint rotational stability. However, no consensus has been reached on the advantages of this technique over the single-bundle technique. Hypothesis We hypothesized that double-bundle anterior cruciate ligament reconstruction could provide better intraoperative stability and clinical outcome than single-bundle reconstruction. Type of study: Cohort study; Level of evidence, 2. Methods Forty patients with anterior cruciate ligament injury in one knee were recruited; 20 were allocated to a double-bundle anterior cruciate ligament reconstruction group and 20 to a single-bundle anterior cruciate ligament reconstruction group. Intraoperative stabilities at 30° of knee flexion were compared between the 2 groups using a navigation system. Clinical outcomes including Lysholm knee scores, Tegner activity scores, Lachman and pivot-shift test results, and radiographic stabilities were also compared between the 2 groups after a minimum of 2 years of follow-up. Results Intraoperative anterior and rotational stabilities after anterior cruciate ligament reconstruction in the double-bundle group were significantly better than those in single-bundle group (P = .020 and P < .001, respectively). Nineteen patients (95%) in each group were available at a minimum 2-year follow-up. Clinical outcomes including Lysholm knee and Tegner activity scores were similar in the 2 groups at 2-year follow-up (P > .05). Furthermore, stability results of the Lachman and pivot-shift tests, and radiologic findings at 2-year follow-up failed to reveal any significant intergroup differences (P > .05). Conclusion Although double-bundle anterior cruciate ligament reconstruction produces better intraoperative stabilities than single-bundle anterior cruciate ligament reconstruction, the 2 modalities were found to be similar in terms of clinical outcomes and postoperative stabilities after a minimum of 2 years of follow-up.

AbstractThe purpose of this study was to report the demographics and clinical outcomes of patients at our institution following anterior cruciate ligament reconstruction (ACLR) with a planned or unplanned hybrid autograft–allograft. At a minimum 2-year follow-up, patients at our institution who had undergone primary ACLR with a planned (P) or unplanned (U) hybrid graft using fresh-frozen allografts were contacted to complete a survey containing the Knee Injury and Osteoarthritis Outcome Score, Subjective International Knee Documentation Committee score, Single Assessment Numeric Evaluation, 12-Item Short Form Health Survey, and visual analog scale for activity level. Demographics were compared between groups. Patient-reported outcomes (PROs) and a revision rate were reported for each group. Mean follow-up among all patients was 3.3 years. Revision rate at follow-up was 0.8 and 6.3% in the P and U groups, respectively (p = 0.03). Among patients reached for follow-up (90 P, 30 U), a lower proportion of males was found in the unplanned hybrid graft group (P: 52%, U: 23%, p < 0.01). Unplanned hybrid graft patients were significantly younger at the time of surgery (P: 41.0 years, U: 31.0 years, p < 0.0001). Graft size did not differ between groups (P: 9.1 mm, U: 8.9 mm, p = 0.11). Patients in both groups achieved moderate to high PROs. Demographics differ between patients undergoing ACLR with a planned or unplanned hybrid graft. Patients with a planned hybrid graft are at a significantly reduced risk of postoperative graft failure, likely due to the older age of this group.

Anterior Cruciate

Background: Biomechanical studies have demonstrated significant loosening of the adjustable-loop device as compared with the fixed-loop device used in anterior cruciate ligament reconstruction. Retensioning of the adjustable loop has been recommended; however, the timing of the retensioning is unknown. Hypothesis: Early (ER) and late retensioning (LR) will show similar gapping between the femoral tunnel and graft on follow-up magnetic resonance imaging (MRI) and similar clinical outcomes. Study Design: Cohort study; Level of evidence, 3. Methods: This study included 101 patients who underwent hamstring anterior cruciate ligament reconstruction using the adjustable-loop device for femoral fixation between June 2016 and January 2018. All patients a had follow-up MRI on postoperative day 1. Patients with revision surgery and those with reinjury after reconstruction were excluded. In the ER group, retensioning and knot tying of the initially tightened adjustable loop were performed after the flip of the button and before the graft was fixed at the tibia. In the LR group, retensioning and knot tying were performed after initial tightening of the adjustable loop and graft fixation at the tibial side. The tunnel-graft gap measured on multiplanar reformatted images of MRI scans was compared between the groups, as were clinical outcomes. Results: The mean age of the patients at the time of surgery was 30.3 years (range, 14-61 years). ER and knot tying were performed in 56 patients and LR and knot tying in 45. Preoperative characteristics of the 2 groups showed no significant differences. The mean ± SD tunnel-graft gap was 1.5 ± 2.0 mm in the ER group and 5.4 ± 4.0 mm in the LR group ( P < .001). There were no significant differences in clinical outcomes between the groups. Conclusion: ER and knot tying demonstrated less tunnel-graft gap than that of LR. However, there were no differences in clinical outcomes according to the timing of retensioning.
