Is Immediate Postoperative Radiograph Necessary Following Robotic-Assisted Total Knee Arthroplasty?

The necessity of immediate postoperative radiographs following total knee arthroplasty (TKA) has long been debated. With the increasing use of robotic-assisted TKA (RTKA), and thus more precise implant placement, the need for immediate postoperative radiographs to determine implant positioning may be unnecessary. We sought to evaluate implant position on the immediate postoperative radiographs following RTKA to determine their necessity.

Publication Rates of Abstracts Presented at American Orthopaedic Society for Sports Medicine Annual Meetings From 2016 to 2019.

Background: Research in the form of poster and podium abstracts is disseminated at subspecialty society meetings. The quality of this research can be defined by exploring the ultimate publication rate of the presented abstracts.

Purpose: To investigate (1) the manuscript publication rate of abstracts presented at the American Orthopaedic Society for Sports Medicine (AOSSM) annual meeting; (2) whether abstract format (poster vs podium) influences overall or 2-year publication rates and time to publication; (3) the abstract factors that are associated with increased publication rate; and (4) whether publication quality as measured by journal of publication, level of evidence (LOE), and number of citations differs between posters and podiums.

A review of chronic pectoralis major tears: what options are available?

Rupture of the pectoralis major muscle typically occurs in the young, active male. Acute management of these injuries is recommended; however, what if the patient presents with a chronic tear of the pectoralis major? Physical exams and magnetic resonance imaging can help identify the injury and guide the physician with a plan for management. Nonoperative management is feasible, but is recommended for elderly, low-demand patients whose functional goals are minimal.

Residency Match Rates in Orthopaedic Surgery Based on Sex, Under-Represented in Medicine Status, and Degree Type.

Unlabelled: Orthopaedic surgery is well recognized as one of the most competitive and least diverse medical specialties. Despite efforts toward improving diversity, studies have shown that gender and racial/ethnic disparities continue to persist in orthopaedic graduate medical education. Therefore, we sought to identify the match rates of traditionally under-represented groups within orthopaedic surgery-female candidates, racial and ethnic minorities under-represented in medicine (URiM), and osteopathic physicians-compared with their application rates.

9-Phenanthrol modulates postinhibitory rebound and afterhyperpolarizing potentials in an excitatory motor neuron of the medicinal leech.

Postinhibitory rebound (PIR) responses in leech dorsal excitatory motor neurons (cell DE-3) are eliminated by Ca channel blockers but also exhibit a strong dependence on extracellular Na. These features could be explained by a voltage-gated Ca current acting in concert with a Ca-activated nonspecific current (I). In vertebrates, I is associated with TRPM4 channels which are blocked selectively by 9-phenanthrol.
