It's hard to believe that we've reached the start of another year, but here we are in 2023, with much to look forward to. 

I'm guessing that many of you will have been enjoying the feast of football recently on offer at the FIFA 2022 World Cup in Qatar. Although there was no shortage of controversy, the football itself was of the highest quality, the tournament culminating in one of the all-time classic finals between winners Argentina and runners-up France. ​

2023 will see the Ninth Women's World Cup tournament, hosted this year in New Zealand and Australia - the largest ever iteration of this tournament with a total of 32 teams competing. Other forthcoming sporting highlights for 2023 include the Rugby World Cup in France, ​Cricket World Cup in India, Pan American games in Chile, and the Netball World Cup in South Africa, as well as all of the regular major annual sporting events around the World. 

​We kick off our first issue of 2023 with an Editorial by Butler and Colleagues on the subject of youth sporting population classification and definitions. Historical inconsistencies of meaning amongst terms used in the youth sports literature, such as 'youth' and 'pediatric,' are discussed. In order to avoid inconsistencies of definitions when referring to certain age ranges of youth populations as described in the literature, the authors propose 3 new subcategories for defining young sports participants based on chronological age: childhood (age 5-12 yrs), early teen (13-15 yrs) and late teen (age 16-18yrs).  It will be interesting to see if these newly-proposed terms become widely adopted amongst researchers involved in youth sports medicine research studies in the future. 

Following on from their previous work, Professor Margo Mountjoy and Colleagues discuss the implementation of the International Olympic Committee Sport Mental Health Assessment Tool 1 (SMHAT-1) as used for mental health screening within a Canadian multisport university program. The results of this study, involving 542 university-level student athletes from 17 different sports, revealed that many students suffered from a variety of mental health symptoms, underlining the need for team physicians to recognise and treat those with mental health symptoms. 

Trbovich and colleagues present a comparison study of clinical outcomes between athletes with immediate and delayed (ie occurring greater than 60 seconds post-event) symptoms as a result of sport-related concussion. In this study of 152 participants aged 11-24, presenting within 7 days of a sports-related concussion, 24.3% of athletes were 'delayed'  supporting the continued evaluation of athletes for several days post-event. Delayed-onset symptoms were associated with post-traumatic migraine, whereas immediate-onset symptoms were associated with more pronounced vestibular symptoms. The authors suggest that clinicians should consider the timing of symptom onset when assessing and treating patients post-sports related concussion. 

Amongst general reviews this month, Dai and Colleagues present a meta-analysis of randomized-controlled trials (RCT) on platelet-rich plasma (PRP) versus placebo for the treatement of tendinopathy.​ Amongst 13 included RCTs, PRP was not shown to be superior to placebo in the treatment of tendinopathy as measured by pain relief and functional improvement either short-term (4 to 6 or 12 weeks) or medium term (longer than 24 weeks). The authors concede that the included studies were hetereogeneous for PRP preparation, and also that included studies had some inherent methodological limitations which may limit the validity of the authors' conclusions. It seems that the jury is still out for PRP, despite it's seemingly increasing popularity. 

We present two more general reviews, including a systematic review by Tuang and colleagues on the biomechanical effects of prophylactic knee bracing on anterior cruciate ligament injury risk, and a systematic review and meta-analysis by Bolia and Colleagues on outcomes for elite athletes following ankle syndesmosis injuries​
