Mixed-Methods Analysis of a Validated Arthroscopic Knot-Tying Simulator With New Indirect Visualization Condition.

Background: Simulation provides low-risk opportunities for surgical trainees to learn and practice fundamental skills. One simulation tool for orthopaedics is the Arthroscopic Knot (ArK) Trainer, which has been validated as an effective simulation tool across multiple methodologies. Previous studies have investigated the ArK Trainer in its basic form using clear plexiglass, which allows direct visualization of tissue anchors.

Comparison of Complications in X-Ray Versus Ultrasound-Guided Hip Arthroscopy.

Purpose: To report the complication rates and frequency of iatrogenic injury to the cartilage and labrum when using an ultrasound-guided hip arthroscopic technique compared with the standard x-ray-guided technique.

Methods: In this retrospective cohort study of prospectively collected data, intraoperative videos were evaluated for iatrogenic injury during portal establishment. Postoperative complications and revision procedures were monitored for 12 months.

Posterior Glenohumeral Capsular Reconstruction Using an Acellular Dermal Allograft.

Posterior shoulder instability is an uncommon and challenging cause of shoulder pain and dysfunction. Surgical management has less reliable results and higher failure rates compared with techniques for anterior shoulder instability. The presence of generalized ligamentous laxity further complicates options for surgical management.

Editorial Commentary: Using Bankart "Plus" Techniques to Tackle Anterior Shoulder Instability With Bone Loss: Can Newer Arthroscopic Adjuncts Provide Long-Term Stability?

The debate between arthroscopic Bankart repair versus the Latarjet technique for patients with anterior shoulder instability largely hinges on the argument between redislocation rate versus complication rate. This difference becomes more apparent when considering patients with bone loss. We believe that Bankart "plus" techniques, including arthroscopic anatomic bone grafting, create a stable shoulder with a low instability recurrence rate, while maintaining a complication rate comparable to the Bankart repair.

Synthesis and biological activities of 4-N-(anilinyl-n-[oxazolyl])-7-chloroquinolines (n=3' or 4') against Plasmodium falciparum in in vitro models.

The synthesis (Pd-mediated coupling strategy) and characterization (NMR, IR, elemental analysis, etc.) of a short series of quinoline-oxazole hybrid compounds has been carried out. These materials are found to be moderately active against Plasmodium falciparum in vitro, with activities in the sub-micromolar range, and to display acceptable cytotoxicity to mononuclear leukocytes.
