Background: Timely removal from activity after concussion symptoms remains problematic despite heightened awareness. Previous studies indicated potential adverse effects of continuing to participate in physical immediately sustaining a concussion. Hypothesis/Purpose: The purpose was determine the effect timing play on clinical outcomes. It hypothesized that immediate sport-related (SRC) would be associated with less time missed sport, shorter symptomatic period, and better outcomes acute...
There is recent evidence that use of allograft tendons for anterior cruciate ligament (ACL) reconstruction in young patients may result increased failure rates compared with autologous grafts.Allograft ACL will higher athletes autograft reconstruction.Cohort study; Level evidence, 2.A prospective cohort study cadets at the United States Military Academy (USMA) was performed to assess performance reconstructions before entrance service. Members classes 2007 through 2013 who had undergone...
Background: There is no consensus on the optimal treatment of in-season athletes with anterior shoulder instability, and limited data are available to guide return play. Purpose: To examine likelihood sport recurrence instability after an event based type (subluxation vs dislocation). Additionally, injury factors patient-reported outcome scores administered at time were evaluated assess predictability eventual successful during competitive season. Study Design: Cohort study (prognosis);...
Context: Few population-based studies have examined the incidence of meniscal injuries, and limited information is available on influence patient's demographic occupational factors. Objective: To examine injuries factors among active-duty US service members between 1998 2006. Design: Cohort study. Setting: Using International Classification Diseases (9th revision) codes 836.0 (medial meniscus), 836.1 (lateral 836.2 (meniscus unspecified), we extracted injury data from Defense Medical...
