Proprioception After Primary Repair of the Anterior Cruciate Ligament Am. J. Sports Med. (IF 4.8) Pub Date : 2024-03-04 Murat Ciceklidag, Ibrahim Kaya, Tacettin Ayanoglu, Inci Hazal Ayas, Mustafa Ozer, Muhammet Baybars Ataoglu, Ulunay Kanatli
Background:Primary repair of the anterior cruciate ligament (ACL) has some potential advantages over the reconstruction technique, which include but are not limited to better knee sensation due to preservation of the natural ACL tissue in patients compared with tendon graft. Proprioception is impaired after ACL injuries and the sense of the joint position is lost.Purpose/Hypothesis:The purpose of this

Background:Based in part on the results of randomized controlled trials (RCTs) that suggest a beneficial effect over alternative treatment options, the use of platelet-rich plasma (PRP) for the management of knee osteoarthritis (OA) is widespread and increasing. However, the extent to which these studies are vulnerable to slight variations in the outcomes of patients remains unknown.Purpose:To evaluate

Passaged Articular Chondrocytes From the Superficial Zone and Deep Zone Can Regain Zone-Specific Properties After Redifferentiation Am. J. Sports Med. (IF 4.8) Pub Date : 2024-02-29 Elizabeth E.R. Davis, Thomas J. Manzoni, Vanessa J. Bianchi, Joanna F. Weber, Po Han Wu, Suresh C. Regmi, Stephen D. Waldman, Tannin A. Schmidt, Alvin W. Su, Rita A. Kandel, Justin Parreno
Background:Bioengineered cartilage is a developing therapeutic to repair cartilage defects. The matrix must be rich in collagen type II and aggrecan and mechanically competent, withstanding compressive and shearing loads. Biomechanical properties in native articular cartilage depend on the zonal architecture consisting of 3 zones: superficial, middle, and deep. The superficial zone chondrocytes produce

The Utility of Stress Ultrasound in Identifying Risk Factors for Elbow Ulnar Collateral Ligament Tear: A Longitudinal Study of 203 Professional Baseball Players Am. J. Sports Med. (IF 4.8) Pub Date : 2024-02-26 Adeeb Jacob Hanna, Hannah R. Popper, John Hayden Sonnier, Brandon J. Erickson, Robert A. Jack, Steven B. Cohen
Background:Injuries to the medial ulnar collateral ligament (UCL) are common among baseball pitchers due to repetitive stress on the soft tissue stabilizers of the elbow during pitching. Dynamic stress ultrasound (SUS) can be used to evaluate the UCL and ulnohumeral joint to identify anatomic risk factors of those who will require UCL reconstruction (UCLR).Purpose:To determine whether any adaptive

The Effect of Acute Knee Injuries and Related Knee Surgery on Serum Levels of Pro- and Anti-inflammatory Lipid Mediators and Their Associations With Knee Symptoms Am. J. Sports Med. (IF 4.8) Pub Date : 2024-02-26 James Turnbull, Rakesh R. Jha, David A. Barrett, Ana M. Valdes, Jennifer Alderson, Andrew Williams, Tonia L. Vincent, Fiona E. Watt, Victoria Chapman
Background:Despite an acute knee injury being a major risk factor for osteoarthritis, the factors that initiate and maintain this risk of longer-term knee symptoms are poorly understood. Bioactive lipids derived from omega-3 and -6 polyunsaturated fatty acids have key roles in the regulation of the inflammatory response and have been linked to joint damage and osteoarthritis pain in translational models

Clinical and Functional Outcomes of Documented Knee Dislocation Versus Multiligamentous Knee Injury: A Comparison of KD3 Injuries at Mean 6.5 Years Follow-up Am. J. Sports Med. (IF 4.8) Pub Date : 2024-02-24 Andrew J. Hughes, Zachary I. Li, Sharif Garra, Joshua S. Green, Isabel Chalem, Jairo Triana, Laith M. Jazrawi, Michael J. Medvecky, Michael J. Alaia
Background:Previous research has found that the incidence of neurovascular injury is greatest among multiligamentous knee injuries (MLKIs) with documented knee dislocation (KD). However, it is unknown whether there is a comparative difference in functional recovery based on evidence of a true dislocation.Purpose:To determine whether the knee dislocation-3 (KD3) injury pattern of MLKI with documented

The Influence of Tibial Tubercle–Sparing Slope-Reducing Osteotomy on Patellar Height in Patients Undergoing Revision ACL Reconstruction Am. J. Sports Med. (IF 4.8) Pub Date : 2024-02-22 Sylvain Guy, Adnan Saithna, Alexandre Ferreira, Alessandro Carrozzo, Thais Dutra Vieira, Matthieu P. Ollivier, Bertrand Sonnery-Cottet
Background:A posterior tibial slope (PTS) >12° is an independent risk factor for anterior cruciate ligament (ACL) graft rupture, and a high tibial osteotomy (HTO) for slope correction can help avoid it. Management of patellar height is of major concern when performing HTO.Purpose:To evaluate the effect of tibial tubercle–sparing anterior closing-wedge osteotomy on patellar height in revision ACL reconstruction

Clinical and Functional Outcomes of Suture Versus Headless Screw Fixation for Tibial Eminence Fractures in Children Am. J. Sports Med. (IF 4.8) Pub Date : 2024-02-22 Niyazi Ercan, Gökhun Arıcan, Kemal Şibar, Ahmet Özmeriç, Serkan İltar
Background:Suture and screw fixations are widely used to treat tibial eminence fractures (TEFs). Although a few biomechanical and clinical studies have compared suture fixation (SF) and screw fixation in the treatment of TEFs in children, no comparative clinical studies are available regarding headless screw fixation (HSF).Purpose:To evaluate the clinical and functional outcomes of children with TEF
