Demographic Factors Associated With an Increased Incidence of Intra-articular Injuries After Delayed Anterior Cruciate Ligament Reconstruction.

Background: Delays from the time of an anterior cruciate ligament (ACL) tear to surgical reconstruction are associated with an increased incidence of meniscal and chondral injuries.

Purpose: To evaluate the association between delays in ACL reconstruction (ACLR) and risk factors for intra-articular injuries across 8 patient demographic subsets.

Study Design: Cross-sectional study; Level of evidence, 3.

Outcomes of reverse shoulder arthroplasty following failed superior capsular reconstruction.

Background: Superior capsular reconstruction (SCR) can be used for massive irreparable rotator cuff tears in the absence of significant degenerative changes; however, those who fail an SCR may require reverse shoulder arthroplasty (RSA). The effect of a previously performed SCR on outcomes following RSA remains unknown.

Methods: Subjects who underwent RSA from May 2015 to January 2021 at 2 separate institutions were retrospectively identified through prospectively collected databases.

Radiographic Appearance of Cosmetic Gluteal Injections in a Patient With Proximal Hamstring Tear: A Case Report.

Case: A 45-year-old woman presented 6 months after a right proximal hamstring repair with worsening pain over her surgical site. Anterior-posterior pelvis x-rays revealed bilateral soft-tissue densities around the hips. Extensive workup revealed no medical basis for the radiographic appearance.

Discoid Lateral Meniscus Saucerization and Treatment of Intrasubstance Degeneration Through an Accessory Medial Portal Using a Small Arthroscope.

Discoid lateral meniscus (DLM) is a rare meniscal variant characterized by an increased amount of meniscal tissue that resembles the shape of a disc as opposed to the typical crescent shape of the lateral meniscus. Surgical intervention is recommended for symptomatic DLM with persistent pain, mechanical symptoms, or motion impairment. The technique described is a reliable and reproducible method to identify and treat intrasubstance degeneration (ID) in the setting of DLM.

Ulna Fractures After Elbow Arthrodesis: A Report of 3 Cases.

Case: Two surgeons performed 3 elbow arthrodesis at 90° elbow flexion secured with a plate and screws. All 3 patients experienced fracture at the most distal aspect of the posterior plate, consistent with a stress riser in this location.

Conclusion: The risk of fracture is likely related to vulnerability of the arm with no elbow flexion and may not be ameliorated by changes in operative technique or bone quality.

Mechanical Considerations for Electrospun Nanofibers in Tendon and Ligament Repair.

Electrospun nanofibers possess unique qualities such as nanodiameter, high surface area to volume ratio, biomimetic architecture, and tunable chemical and electrical properties. Numerous studies have demonstrated the potential of nanofibrous architecture to direct cell morphology, migration, and more complex biological processes such as differentiation and extracellular matrix (ECM) deposition through topographical guidance cues. These advantages have created great interest in electrospun fibers for biomedical applications, including tendon and ligament repair.

Evidence of Altered Mitochondrial Protein Expression After Chronic Ethanol Consumption in the Aged Estrogen-Deficient Female Rat Heart.

Background: Estrogen loss has been implicated to increase the risk of alcoholic cardiomyopathy in postmenopausal women. The purpose of this study was to identify novel mitochondrial protein targets for the treatment of alcoholic cardiomyopathy in aged women using a state-of-the-art proteomic approach. We hypothesized that chronic ethanol (EtOH) ingestion exacerbates maladaptive mitochondrial protein expression in the aged female heart.

Comparison of the agar block and Lieber-DeCarli diets to study chronic alcohol consumption in an aging model of Fischer 344 female rats.

Introduction: Post-menopausal women have a greater risk of developing alcoholic complications compared to age-matched men. Unfortunately, animal models of chronic ethanol consumption with estrogen deficiency are lacking. Here, we characterize the ability of the agar block and Lieber-DeCarli models of chronic ethanol consumption to produce elevated blood alcohol content (BAC) and liver pathology in the F344 postmenopausal animal model of aging.
