The outcomes of quadriceps tendon autograft for anterior cruciate ligament reconstruction in adolescent athletes: a retrospective case series.

Eur J Orthop Surg Traumatol 2021 Jun 10. Epub 2021 Jun 10.

Department of Orthopaedics, Penn State Health Milton S. Hershey Medical Center, 500 University Dr., 414 Hallmark South, Hershey, PA, 17033, USA.

Background: Multiple graft options exist for anterior cruciate ligament (ACL) reconstruction in an adolescent athlete. Patellar tendon harvest can lead to anterior knee pain, while hamstring tendon harvest can affect knee flexion strength and alter mechanics. Allograft is less desirable in pediatric patients due to the higher failure rate and slight risk of disease transmission. Read More

Editorial Commentary: Ligamentum Teres Reconstruction May Improve Hip Stability But Has High Revision Rates: Fad or Restoration of Function?

Arthroscopy 2021 Jun;37(6):1820-1821

Robbinsdale, Minnesota.

Ligamentum teres (LT) tears are correlated with hip instability, and biomechanical research suggests there is a stabilizing function of the intact native LT. With regard to LT reconstruction, currently, there are imaging studies demonstrating that the ligament goes on to heal and properly function. There are also no long-term clinical studies on the success rates of LT reconstruction. Read More

Comparison of Cellular Responses to TGF-β1 and BMP-2 Between Healthy and Torn Tendons.

Am J Sports Med 2021 Jun;49(7):1892-1903

Botnar Research Centre, Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences, University of Oxford, Oxford, UK.

Long-term Outcomes of Delayed Scapholunate Ligament Repair After Complete Rupture of the Ligament.

Orthopedics 2021 May-Jun;44(3):e446-e453. Epub 2021 May 1.

Treatment of isolated complete tear of the scapholunate ligament is challenging. The purpose of this study was to determine (1) whether delayed repair of only scapholunate ligament is an option without other reconstruction procedures and (2) whether functional outcomes are possible despite radiographic presence of arthritis. This study included patients who had complete ligament tear at exploration and underwent only scapholunate ligament repair without capsulodesis or tenodesis. Read More

The Natural History of Medial Meniscal Tears in the ACL Deficient and ACL Reconstructed Rat Knee.

Cartilage 2021 May 24:19476035211014588. Epub 2021 May 24.

Department of Rehabilitation, Faculty of Rehabilitation, Hiroshima International University, Higashi-Hiroshima, Hiroshima, Japan.

Objective: The process of anterior cruciate ligament (ACL) injury-induced meniscal tear formation is not fully understood. Clinical studies have shown that ACL reconstruction (ACLR) reduces the development of secondary meniscal tears, but it is difficult to gain insight into the protective effects of ACLR from clinical studies alone. Using rat ACL transection (ACLT) and ACLR models, we aimed to reveal (1) the formation process of meniscal tears secondary to ACLT and (2) the protective effects of ACLR on secondary meniscal tears.

Comparison of hamstring and quadriceps tendon autografts in anterior cruciate ligament reconstruction with gait analysis and surface electromyography.

J Orthop Traumatol 2021 May 21;22(1):20. Epub 2021 May 21.

Clinic for Orthopedics and Trauma Surgery, University Medical Center Schleswig Holstein UKSH Campus Luebeck, Ratzeburger Allee 160, 23538, Luebeck, Germany.

Background: Anterior cruciate ligament (ACL) tear is the most frequent ligamentous injury of the knee joint. Autografts of hamstring (HS) or quadriceps tendons (QT) are used for primary ACL reconstruction.

The Oblique Meniscomeniscal Ligament: A Case Report of a Rare Obstruction to Meniscal Root Repair.

JBJS Case Connect 2021 05 19;11(2). Epub 2021 May 19.

Twin Cities Orthopedics, Edina-Crosstown, Edina, Minnesota.

Case: The authors present a case of a 41-year-old woman who was treated for a chronic type 2 posterior horn tear of the medial meniscal root. During an arthroscopic repair, a broad, thick ligament coursing through the intercondylar notch caused difficulty in visualizing the posterior joint space and necessitated creation of an accessory portal. Given its course and attachments, this structure was an example of a rare variant of anatomy, an oblique meniscomeniscal ligament. Read More

Interpretable and Lightweight 3-D Deep Learning Model For Automated ACL Diagnosis.

IEEE J Biomed Health Inform 2021 May 18;PP. Epub 2021 May 18.

We propose an interpretable and lightweight 3D deep neural network model that diagnoses anterior cruciate ligament (ACL) tears from a knee MRI exam. Previous works focused primarily on achieving better diagnostic accuracy but paid less attention to practical aspects such as explainability and model size. They mainly relied on ImageNet pre-trained 2D deep neural network backbones, such as AlexNet or ResNet, which are computationally expensive. Read More
