Objectives: The Bridge-Enhanced ACL Repair (BEAR) procedure is an alternate form of anterior cruciate ligament (ACL) surgery that involves suture repair of the ligament combined with a scaffold to bridge the gap between the torn ligament ends. In this paper, we report outcomes of this procedure and a non-randomized concurrent control group receiving ACL reconstruction with quadrupled hamstring tendon autograft. We hypothesized that patients treated with Bridge-Enhanced ACL Repair would have physical exam findings, patient reported outcomes and adverse events at one and two years that were similar to patients treated with ACL reconstruction. Methods: This was an observational cohort study. Twenty patients were enrolled. Ten patients received a Bridge-Enhanced ACL Repair (BEAR®) and 10 received a hamstring autograft ACL reconstruction. Outcomes were assessed at time points up to 2 years post-operatively, including the International Knee Documentation Committee (IKDC) Subjective Score, the IKDC Objective score, KT-1000 testing for AP laxity and functional testing. Results: There were no graft or repair failures in the first two years after surgery. The IKDC Subjective Scores in both groups improved significantly from baseline (p< 0.0001) but were similar in BEAR and ACL reconstruction groups at 12 and 24 months. An IKDC Objective score of A (normal) was found in 44% of the patients in the BEAR group and 29% of the patients in the ACL reconstruction group at two years; no patients in either group had a grade of C (abnormal) or D (severely abnormal). KT-1000 testing demonstrated a side to side difference that was similar in the two groups at 2 years (mean(±SD) 1.9(± 2.1) mm in the BEAR group, 3.1(± 2.7) mm in the ACLR group). Functional hop testing results were similar in the two groups at 1 and 2 years after surgery. Hamstring strength indices measured by dynamometer were significantly higher at all time points in the BEAR group than in the hamstring autograft group (mean percentages relative to contralateral side at two years, 98.6%(±10.5%) vs 56.3%(±19.0%), p=0.0001). Conclusion: In a small first-in-human study, Bridge-Enhanced ACL Repair produced similar outcomes to ACL reconstruction with autograft quadruple bundle hamstring tendon.

Abstract Purpose The purpose of this study was to evaluate sports activity before anterior cruciate ligament (ACL) injury and after surgical treatment of ACL rupture comparing ACL repair with an Internal Brace to ACL reconstruction using either a hamstring (HT) or quadriceps tendon (QT) autograft. Methods Between 12/2015 and 10/2016, we recruited 69 patients with a mean age of 33.4 years for a matched-pair analysis. Twenty-four patients who underwent Internal Brace reconstruction were matched according to age (± 5 years), gender, Tegner activity scale (± 1), BMI (± 1) and concomitant injuries with 25 patients who had undergone HT reconstruction and 20 patients who had undergone QT reconstruction. The minimum follow-up was 12 months. Results Overall, the return-to-sports rate was 91.3 %. There were no significant differences (p ≥ 0.05) in the number of sports disciplines and the time before return to sports within or among the groups. Overall and within the groups, the level of sports participation did not change significantly (p ≥ 0.05) postoperatively. The patients' sense of well-being was excellent after either ACL repair with an Internal Brace or ACL reconstruction with autologous HT or QT. Conclusion At short-term follow-up, ACL repair using an Internal Brace enables sports activity and provides a sense of well-being similar to that of classic ACL reconstruction using hamstring or quadriceps tendon autografts in a selected patient population. Level of Evidence: Level III Retrospective comparative study.

Background: Anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries in skeletally immature patients are increasingly recognized and surgically treated. However, the relationship between the footprint anatomy and the physes are not clearly defined. The purpose of this study was to identify the origin and insertion of the ACL and MCL, and define the footprint anatomy in relation to the physes in skeletally immature knees. Methods: Twenty-nine skeletally immature knees from 16 human cadaver specimens were dissected and divided into two groups: Group A (ages 2-5 years), and Group B (ages 7-11 years). Metallic markers were placed to mark the femoral and tibial attachments of the ACL and MCL. CT scans were obtained for each specimen used to measure the distance from the center of the ligament footprints to the respective distal femoral and proximal tibial physes. Results: Median distance from the ACL femoral epiphyseal origin to the distal femoral physis was 0.30 cm (interquartile range, 0.20 cm to 0.50 cm) and 0.70 cm (interquartile range, 0.45 cm to 0.90 cm) for Groups A and B, respectively. The median distance from the ACL epiphyseal tibial insertion to the proximal tibial physis for Groups A and B were 1.50 cm (interquartile range, 1.40 cm to 1.60 cm) and 1.80 cm (interquartile range, 1.60 cm to 1.85 cm), respectively. Median distance from the MCL femoral origin on the epiphysis to the distal femoral physis was 1.20 cm (interquartile range, 1.00 cm to 1.20 cm) and 0.85 cm (interquartile range, 0.63 cm to 1.00 cm) for Groups A and B, respectively. Median distance from the MCL insertion on the tibial metaphysis to the tibial physis was 3.05 cm (interquartile range, 2.63 cm to 3.30 cm) and 4.80 cm (interquartile range, 3.90 cm to 5.10 cm) for Groups A and B, respectively. Conclusion: Surgical reconstruction is a common treatment for ACL injury, and occasionally MCL reconstruction or repair is also required. Cadaveric dissection and CT scanning of exceptionally rare pediatric tissue clearly defines the location of the ACL and MCL with respect to the femoral and tibial physes, and may guide surgeons for physeal respecting procedures for both ACL reconstruction, and ACL repair procedures. Clinical Relevance: In addition to ACL reconstruction, recent basic science and clinical research suggest that ACL repair may be more commonly performed in the future. MCL repair and reconstruction is also occasionally required in skeletally immature patients. This information may be useful to help surgeons avoid or minimize physeal injury during ACL/MCL reconstructions and/or repair in skeletally immature patients.

Abstract Introduction The object of this study was to evaluate the primary stability of tibial interference screw (IFS) fixation in single-stage revision surgery of the anterior cruciate ligament (ACL) in the case of recurrent instability after ACL repair with dynamic intraligamentary stabilization (DIS), dependent on the implant position during DIS. Materials and methods Tibial aperture fixation in ACL reconstruction (ACL-R) was performed in a porcine knee model using an IFS. Native ACL-R was performed in the control group (n = 15). In the intervention groups DIS and subsequent implant removal were performed prior to single-stage revision ACL-R. A distance of 20 mm in group R-DIS1 (n = 15) and 5 mm in group R-DIS2 (n = 15) was left between the joint line and the implant during DIS. Specimens were mounted in a material-testing machine and load-to-failure was applied in a worst-case-scenario. Results Load to failure was 454 ± 111 N in the R-DIS1 group, 154 ± 71 N in the R-DIS2 group and 405 ± 105 N in the primary ACL-R group. Load-to-failure, stiffness and elongation of the group R-DIS2 were significantly inferior in comparison to R-DIS1 and ACL-R respectively (p < 0.001). No significant difference was found between load-to-failure, stiffness and elongation of R-DIS1 and the control group. Conclusion Primary stability of tibial aperture fixation in single-stage revision ACL-R in case of recurrent instability after DIS depends on monobloc position during ACL repair. Primary stability is comparable to aperture fixation in primary ACL-R, if a bone stock of 20 mm is left between the monobloc and the tibial joint line during the initial procedure.

Anterior Cruciate

Primary repair of the Anterior Cruciate Ligament (ACL) had some popularity among a select group of surgeons in the mid 20th century. Techniques described by Ivar Palmer of Sweden were adopted in the United States by surgeons such as O’Donoghue, Marshall, and Feagin. However, promising early results were followed by disappointing failure rates at 5-year follow-up, and ACL reconstruction became the norm. Recently there has been a renewed interest in ACL repair. One use has been in conjunction with ACL reconstruction as remnant preservation. Isolated repair has been reported using a variety of techniques, including bridge-enhanced repair (BEAR) with a sheath, meticulous suturing with or without suture tape reinforcement, and repair to a dynamic intraligamentary stabilization (DIS) device. Early reports have been encouraging. However, in the case of the BEAR, the series is so far small and short-term; the two other techniques have more results reported but they include some studies with a concerning level of failure, especially in younger or more active patients. My current recommendation is to await more clinical documentation before adopting these technique in lieu of ACL reconstruction.
