An intense, focused beam is created from emission of light waves in the same phase and at the same frequency (i.e., coherent).

The Academy’s Board of Directors met last month during the AAOS 2019 Annual Meeting and approved two completely updated Clinical Practice Guidelines (CPGs): one on periprosthetic joint infection (PJI) and the other on rotator cuff injuries (RCIs).
