Several factors affect the success of an anterior cruciate ligament reconstruction, including graft origin, type, and morphology. Hamstring and bone-patellar tendon-bone autografts are the most widely used, and there are many different techniques of graft preparation with each. In this Technical Note and accompanying video, a 4-strand hamstring autograft technique is described that uses a simple diamond-type braid to produce a more ovoid morphology with increased cross-sectional area. Increased graft diameters have been associated with higher success rates and more positive long-term outcomes. Therefore, this braiding construct may provide additional tensile strength with increased resistance to failure than grafts that are otherwise undersized using conventional techniques.

Purpose: This study aimed to compare the return to sports, return to competition, Tegner score and anterior cruciate ligament-return to sports injury (ACL-RSI) scores between patients who underwent ACL reconstruction (ACLR) combined with anterolateral ligament reconstruction (ALLR) and those who underwent ACLR alone.
Methods: Two independent reviewers conducted a literature search in PubMed (MEDLINE), EMBASE, Google Scholar and the Cochrane Library in July 2024, followed by data extraction and quality assessment. This study followed the Preferred Reporting Items for Systematic Reviews and meta-analysis guidelines.
Minimizing Unnecessary Harvesting of an Extremely Thin Gracilis Tendon During ACL Reconstruction by Referencing the Diameter of the Doubled Semitendinosus Tendon Alone.

Background: The incidence of anterior cruciate ligament reconstruction (ACLR) graft failure is inversely related to the diameter of the ACLR graft. When the diameter of a 4-stranded hamstring tendon graft with a doubled semitendinosus and doubled gracilis tendon (ST×2 + G×2) configuration is <8 mm, the gracilis tendon is often thin.
Hypothesis: (1) The diameter of the doubled semitendinosus tendon (ST×2) alone would be able to predict the probability of a 4-stranded ACLR graft having a diameter of ≥8 mm, and (2) there would be a specific cutoff value for the ST×2 diameter such that the addition of a doubled gracilis tendon (G×2) will not result in a 4-stranded graft with a ≥8-mm diameter.
Uncovering the State of Current Data on Quadriceps Tendon Autograft Use Versus Bone-Patellar Tendon-Bone and Hamstring Tendon Autografts in Anterior Cruciate Ligament Reconstruction at ≥5 Years After Surgery: A Systematic Review and Meta-analysis.

Department of Orthopaedic Surgery, University of Cincinnati, Cincinnati, Ohio, USA.
Background: The use of quadriceps tendon (QT) autograft for anterior cruciate ligament (ACL) reconstruction has been increasing since 2014. Studies have shown that QT is comparable to hamstring tendon (HT) and bone-patellar tendon-bone (BTB) autografts in terms of outcomes, although QT autograft has lower rates of donor site morbidity. Systematic reviews and meta-analyses have been previously conducted on this topic, although none have focused solely on data of patients at least 5 years out from surgery.

Background: Patients with simultaneous ruptures of the patellar tendon (PT) and anterior cruciate ligament (ACL) underwent PT repair and ACL reconstruction in a single or staged surgery. However, due to the limited cases, the design of previous studies was mostly case report with varying conclusions regarding recommended surgical strategy selection, the optimal surgical strategy remains a subject of debate.
Methods: We conducted a retrospective case series and literature review, including 10 cases from local institution and 27 cases from 17 studies.
[Effectiveness of peripheral nerve blockade in pain management for patients undergoing anterior cruciate ligament reconstruction: a retrospective observational study].
Acta Ortop Mex

Unidad de Investigación. Clínica INDISA. Santiago, Chile.
Introduction: therapeutic equivalence has been established in the effectiveness of peripheral nerve blocks in the management of pain in the postoperative period of anterior cruciate ligament reconstruction. However, it is unknown whether this effect is modulated by the anesthesiologist's experience. The objective was to describe the effectiveness of peripheral nerve blocks during the first 24 hours of the postoperative period, considering patient characteristics and the anesthesiologist's experience.
