Anterior Cruciate Ligament Reconstruction Basics: Quadriceps Tendon (All-Soft Tissue) Autograft Preparation-Part 2.

Anterior cruciate ligament reconstruction with quadriceps tendon autograft is a reliable graft option that has recently increased in use. Varying harvesting and graft preparation techniques available and improved technology and implant design continue to make quadricep tendon preparation more efficient and reproducible. In this Technical Note, we describe our preferred technique for all-soft tissue quadriceps tendon autograft preparation after harvest for anterior cruciate ligament reconstruction.

Anterior Cruciate Ligament Reconstruction Basics: Quadriceps Tendon (All-Soft Tissue) Autograft Harvest-Part 1.

Anterior cruciate ligament reconstruction with quadriceps tendon autograft has become increasingly popular for primary and revision anterior cruciate ligament reconstruction surgery. Although there are a variety of techniques available for performing quadriceps tendon autograft harvest for anterior cruciate ligament reconstruction, a minimally invasive, all-soft tissue harvest technique can result in a reproducible, reliable graft while minimizing donor-site morbidity. In this Technical Note, we describe our preferred technique for quadriceps tendon autograft harvest for anterior cruciate ligament reconstruction.

Rotator Cuff Repair Study Designs Correlate With Revision Shoulder Surgery Rates: A Systematic Review.

Purpose: To identify arthroscopic rotator cuff repair study groups and evaluate if study design or other study characteristics correlate with a repeat ipsilateral shoulder surgery.

Methods: A systematic search of the PubMed, Embase, and Cochrane Library databases was conducted on March 20, 2021, and April 2, 2021. The following search terms were used by 2 different researchers: ((Rotator cuff repair[Title/Abstract]) AND (Revision[Title/Abstract]) NOT (Systematic Review[Title/Abstract]) NOT (arthroplasty[Title/Abstract]).

Facile Synthetic Access Towards Sulfur- and Selenium-Functionalized Boron-Based Multiresonance TADF Emitters.

Thermally activated delayed fluorescence (TADF) materials with high photoluminescence quantum yields and a fast reverse intersystem crossing (RISC) are of the highest interest for organic light-emitting diodes (OLEDs). In the past decade, triaryl boranes with multiple resonance effect (MR) have captured significant attention. The efficiency of MR-TADF emitters strongly depends on small singlet-triplet energy gaps (ΔE), but also on large reverse intersystem crossing (RISC) rate constants (k).
