The Impact of Signaling on the 2022 to 2023 Orthopaedic Residency Application Cycle: A Survey of Incoming Residents.

Background: During the 2022 to 2023 orthopaedic surgery residency application cycle, "signaling" was added, allowing applicants to communicate strong interest to 30 programs of their choosing. This study's purpose was to evaluate signaling's impact on the 2022 to 2023 application cycle.

Methods: A cross-sectional survey was distributed to applicants who applied to a single residency program.

Open and Percutaneous Approaches Have Similar Biomechanical Results for Primary Midsubstance Achilles Tendon Repair: A Meta-analysis.

Purpose: To evaluate the biomechanical properties of open versus percutaneous Achilles tendon repair.

Methods: A systematic review of original research articles was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. To qualify for study inclusion, articles were required to be published in English, use a laboratory design using either human or animal tissue, and directly compare the biomechanical properties of open Achilles repair using a Krackow or Kessler technique with percutaneous repair using either a locking or nonlocking suture construct.

Management of the Mangled Extremity.

Mangled extremities represent one of the most challenging injuries. They indicate the need for a comprehensive trauma assessment to rule out coexisting injuries. Treatment options include amputation and attempts at limb salvage.

Biomechanics of subscapularis V-shaped tenotomy compared to standard tenotomy.

Background: Subscapularis function is critical after anatomic total shoulder arthroplasty (aTSA). Recently, however, a technique has been described that features a chevron or V-shaped subscapularis tendon cut (VT). This biomechanical study compared repair of the standard tenotomy (ST), made perpendicular to the subscapularis fibers, to repair of the novel VT using cyclic displacement, creep, construct stiffness, and load to failure.

Five-Strand Hamstring Grafts are Biomechanically Comparable to Four-Strand Grafts and Offer Greater Diameter for Anterior Cruciate Ligament Reconstruction.

Purpose: The purpose of this study was to compare the biomechanics of 4-strand and 5-strand hamstring constructs for anterior cruciate ligament grafts.

Methods: Thirty-six human cadaveric hamstring grafts were tested in 3 different conditions: (1) graft femoral fixation complex, (2) graft femoral and tibial fixation (GFTF) complex using a human model, and (3) GFTF complex using a porcine model. Grafts were tested on a tensile testing machine.

Biomechanical Comparison of Meniscal Allograft Root Fixation Techniques: Anterograde Interference Bone Plug Fixation Yields Favorable Results Compared to Transosseous Suture Fixation Alone.

Purpose: To compare the biomechanical properties of 2 different fixation techniques (interference bone plug fixation vs transosseous suture fixation) of the posterior horn of the medial meniscus using a porcine model.

Methods: Twenty-six matched pairs of fresh-frozen juvenile domestic porcine knees were used in this study. Specimens were randomly distributed among 3 groups: (1) native meniscus groups, (2) interference fixation, and (3) transosseous suture fixation.

Personalized Fiber-Reinforcement Networks for Meniscus Reconstruction.

The menisci are fibrocartilaginous tissues that are crucial to the load-sharing and stability of the knee, and when injured, these properties are compromised. Meniscus replacement scaffolds have utilized the circumferential alignment of fibers to recapitulate the microstructure of the native meniscus; however, specific consideration of size, shape, and morphology has been largely overlooked. The purpose of this study was to personalize the fiber-reinforcement network of a meniscus reconstruction scaffold.
