Welcome everyone to the first Issue of the Clinical Journal of Sport Medicine in 2020, and let me be the first to wish all of our readers a very happy New Year. I'm excited to find us entering not just a New Year, but a new decade in which there will be much to look forward to both in the World of Sport and of Sports Medicine.

Over the last ten years, and going back to our first Issue back in October 1991, we have been proud to have been able to bring you a great wealth of Original Research from Institutions and researchers based all over the World. It's hard to believe that CJSM is nearly 30 years old!

CJSM continues to champion the work of our contributing Authors, and I'd like to take this opportunity to thank all of those who have sent in their work to us for consideration of publication in our Journal over the years. Thanks too to all of our valued Reviewers who spend so much of their precious time offering their expertise and advice to our Authors, and in helping to ensure that our peer review process results in the best quality research available to our valued readership.

This year, we look forward to what is officially known as the Games of the XXXII Olympiad (2020 Summer Olympic Games) and the 2020 Summer Paralympic Games which will both be based in Tokyo, Japan, from July to September inclusive. 2020 marks the second time that both Games have been held in Tokyo, and the fourth time that the Games have been held in Japan. We also look forward to the EUFA Euro 2020 Football Championships which will be held in 12 cities in 12 UEFA countries from 12 June to 12 July 2020. There are many other wonderful sporting occasions to look forward to, and I am sure that you will have your own personal favourites.

We are also looking forward to another great year of Original Research, and bringing you the best and most clinically-relevant information at the cutting edge of the World of Sports Medicine. We hope that the work published in CJSM will help you to improve your clinical practice, and will help to lead to improved patient outcomes.

We kick off this year with a number of Original Research articles examining the effects of various interventions on health outcomes.

Many of our readers will remember the Scientific Statement from our Affiliate Society, the American Medical Society for Sports Medicine (AMSSM) which was published in 2016 concerning viscosupplementation injections for Knee Osteoarthritis. This work concluded that hyaluronic acid injections were indeed efficacious for the treatment of knee osteoarthritis. In this month's Issue, Dallari and Colleagues examine the efficacy of Intra-articular polynucleotides associated with hyaluronic acid versus hyaluronic acid alone for the treatment of knee osteoarthritis.

In a randomized-controlled trial, 98 patients of Kellgren Lawrence Grade 2 scores were randomized to receive polynucleotide hyaluronic acid versus hyaluronic acid alone over a course of 3 weekly injections. Outcomes including KSS and WOMAC scores were assessed. The study found that KSS total scores decreased significantly in both groups, showing greater decreases in the polynucleotide hyaluronic acid group, and WOMAC scores were improved in both groups over time (1 year follow-up). The Authors concluded that intra-articular injections of polynucleotide hyaluronic acid led to greater improvements in knee function and pain when compared with injections of hyaluronic acid alone. It would be interesting to see if these improvements could be sustained over a greater period of time, and also in a larger study with more patients.

Bridges and Colleagues examine the effects of oral hypertonic saline in comparison to a bolus of intravenous hypertonic saline in symptomatic exercise-associated hyponatremic (EAH) triathlon finisher athletes. An unexpected study finding was significantly faster time to symptom resolution of mild-to-moderate symptomatic EAH with 100 mL of oral hypertonic saline when compared with intravenous hypertonic saline. The Authors concluded that oral hypertonic saline is a safe and practical treatment in the field for this condition.

Wheeler and Colleagues examine the effects of extra-corporeal shockwave therapy versus image-guided high volume injections of lignocaine and sterile saline for chronic non-insertional achilles tendinopathy in a prospective cohort study of 63 patients, who received either a single high volume injection or a course of 3 treatments of extra-corporeal shockwave therapy, with both groups also receiving a standardised, structured home exercise program of flexibility and eccentric strengthening exercises. The Authors found no difference in clinical outcomes between both groups, with similar improvements for both groups.

Other Original Research articles this month include the use of a pocket-sized ultrasound device in the diagnosis of shoulder pathology, the association between foot posture and lower limb-related injuries in professional male basketball players, and musculoskeletal injury in paddle sport athletes, amongst others.

Shanmugaraj and Colleagues present a General Review article asking how useful the Flexion-Adduction-Internal Rotation (FADIR) test is in diagnosing Femoroacetabular Impingement (FAI). We also bring you another General Review article by Brock and Colleagues on the use of actovegin in musculoskeletal medicine over the last 10 years.

For those of you who enjoy reading interesting Case Reports, we offer a grand total of eight different cases this month which are all available on the web. These diverse cases reports include Total Disc Replacement Surgery in a Professional Australian Rugby League Player, Rupture of the Patellar Tendon after Platelet-rich Plasma Treatment, and Catastrophic Return to Play in Rugby after Double Cervical Arthrodesis amongst others.

As ever, James MacDonald brings you up-to-date with the latest research and events in the World of Sports Medicine on our CJSM Blog, on our twitter account on @CJSMonline and on our Facebook account. 

Also, don't forget to check out our ever-increasing bank of CME articles on the CME Lippincott CME Connection website

Here's wishing you a great start to the New Year and to the New Decade ahead!

Best Wishes,
