OBJECTIVE: Strength training acute programme variables (APVs) can impact tibiofemoral joint injury outcomes. Exercise descriptors (EDs; e.g. patient-position) specify configurations within which APVs are applied. Evidence-based practice depends on adequate reporting of APVs and EDs to replicate strength training interventions in clinical practice. This systematic review assessed APV and ED reporting for adults with tibiofemoral joint injury (anterior cruciate ligament (ACL)/posterior cruciate ligament (PCL)/medial collateral ligament (MCL)/lateral collateral ligament (LCL)/meniscus/hyaline cartilage (HC))...

STUDY DESIGN: Case series. BACKGROUND: There is conflicting opinion on the incidence of pelvic avulsion injury within the literature, being depicted as both population and mechanism specific. A recent spate of pelvic avulsion fractures highlighted the condition and the need for greater awareness amongst stakeholders involved in the development of academy footballers. CASE DESCRIPTION: This case report describes a series of six pelvic avulsion injuries within a category 1 football academy season...
