'That time of the month' … for the biggest event of your career! Perception of menstrual cycle on performance of Australian athletes training for the 2020 Olympic and Paralympic Games.

Objective: This study explored the perceived effect of the menstrual cycle (MC) on the performance of Australian female athletes, preparing for the Tokyo Olympic and/or Paralympic Games.

Methods: 195 female athletes, nominated by 24 National Sporting Organisations as preparing for the Tokyo Olympic and/or Paralympic Games, completed an online questionnaire ('MCq perceptions'). The MCq perceptions investigated menstrual symptoms, hormonal contraceptive (HC) use and a preferred competition window within the MC.

Quadriceps Tendon Versus Hamstring Tendon Autografts for Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis.

Background: Autograft choice in anterior cruciate ligament reconstruction (ACLR) remains controversial, with increasing interest in the usage of quadriceps tendon (QT) autograft versus traditional hamstring tendon (HT) use. The current study undertakes an in-depth review and comparison of the clinical and functional outcomes of QT and HT autografts in ACLR.

Hypothesis: The QT autograft is equivalent to the HT autograft and there will be little or no significant difference in the outcomes between these 2 autografts.

Effect of tranexamic acid in arthroscopic anterior cruciate ligament repair: A systematic review and meta-analysis of randomised clinical trials.

Purpose: Perioperative blood loss remains a major challenge to surgeons in anterior cruciate ligament reconstruction (ACLR) surgery, despite of the introduction of minimally invasive approach. Tranexamic acid (TXA) is believed to reduce blood loss, which may minimise the complication of postoperative haemarthrosis with insufficient evidence on its effectiveness in ACLR. The primary aim of this study was to examine the effect of TXA on postoperative blood loss and other secondary outcomes in patients undergoing arthroscopic ACLR surgery.
