Current status of virtual reality simulation education for orthopedic residents: the need for a change in focus.

Introduction: Advances in technology are changing surgical education. Simulation provides an important adjunct to operative experience. This pedagogy has arguably become more important in light of the COVID-19 pandemic, with resultant reduction in operative exposure for trainees.

Simulation training to retool practicing orthopedic surgeons is rare.

Purpose: Modern surgical practice is continuously changing as technology develops. New techniques are often implemented after a surgeon has made the transition to independent clinical practice. There is therefore a need to 'retool' technical skills.

Positive early clinical outcomes of bone marrow aspirate concentrate for osteoarthritis using a novel fenestrated trocar.

Background: This study sought to assess early clinical outcomes for knee osteoarthritis (OA) patients undergoing bone marrow aspirate concentrate (BMAC) treatment using a novel closed-end, fenestrated trocar (FT) that does not require centrifugation.

Methods: A prospective cohort of 17 knee OA patients undergoing BMAC treatment with the FT system from March 2018 to March 2019 was retrospectively evaluated. Approximately 10 mL of BMAC was harvested, no centrifugation was performed, and the BMAC was injected into the affected knee.
