Patients’ Understanding of OA After Knee Injury

Patient Knowledge and Beliefs About Knee Osteoarthritis After Anterior Cruciate Ligament Injury and Reconstruction

Bennell KL, Ginckel AV, Kean CO, Nelligan RK, French SD, Stokes M, Pietrosimone B, Blackburn T, Batt M, Hunter DJ, Spiers L, & Hinman RS.  Arthritis Care Res. 2016;68:1180-1185. doi: 10.1002/acr.22794

Take Home Message: Patients who suffered a knee injury have some understanding of their long-term risks.  However, there is an astoundingly low number of patients who recall having conversations with health care professionals about the long-term risks after an injury. 

We have an earlier post on Sports Med Res about athletic trainers’ knowledge and perceptions of osteoarthritis (OA) after a knee injury.  While it is important for sports medicine clinicians to be aware about OA, it is even more important that this information is communicated to patients who suffer a knee injury.  Therefore, the authors of this research study wanted to assess the knowledge of patients who had suffered a knee injury about OA, and whether these individuals had conversations with their health professional about their OA risks.

Osteoarthritis May Be Associated With More Than Just Joint Pain

Osteoarthritis is Associated with Symptoms of Common Mental Disorders Among Former Elite Athletes 

Shuring N., Aoki H., Gray J., Kerkhoffs GM., Lambert M., Gouttebarge V. Knee Surg Sports Traumatol Arthrosc 2016; ahead of print

Take Home Message: Former elite athletes with osteoarthritis are more likely to have symptoms of common mental disorders (distress, sleep problems, adverse alcohol use) compared to those without osteoarthritis.

Osteoarthritis (OA) is one of the most debilitating joint pathologies worldwide as it leads to physical pain and disability, which can also impact a patient’s mental health. Former elite athletes in certain sports are at risk for OA or report symptoms of mental health disorders. However, it is unclear the extent too which OA among elite athletes is associated with symptoms of common mental disorders. Therefore, the authors collected survey data from 602 (28% response rate) former elite athletes within 5 sports (rugby, football, ice hockey, cricket, and Gaelic players; ~37 years of age) to assess common mental disorders and history of a diagnosis of OA.

Has There Been Any Change in ACL Injury Rates?

Collegiate ACL injury rates across 15 sports: National Collegiate Athletic Association injury surveillance system data update (2004-2005 through 2012-2013)

Agel J, Rockwood T, and Klossner D. Clin J Sport Med. 2016. [Epub Ahead of Print].

Take Home Message: Anterior cruciate ligament (ACL) injury affect a small number of athletes. While overall ACL injury rates are decreasing, ACL injuries still affect a disproportionally higher number of women than men.

Anterior cruciate ligament (ACL) injury research has led to the implementation of preventative programs to decrease the risk of injury. Updated injury surveillance data can be useful in both evaluating the effectiveness of current clinical practice as well as directing future research. Therefore, Agel, Rockwood, and Klossner used NCAA ACL injury surveillance data to determine the rate of ACL injury among collegiate athletes from 2004 to 2013. This is an update of the data previously reported for the 15 academic years between 1988 to 2004.

How much is too much? International Olympic Committee consensus statements on load in sport and risk of injury and illness

How much is too much? (Part 1) International Olympic Committee consensus statement on load in sport and risk of injury

Soligard T, Schwellnus M, Alonso JM, Bahr R, Clarsen B, Dijkstra HP, Gabbett T, Gleeson M, Hägglund M, Hutchinson MR, Janse van Rensburg C, Khan KM0, Meeusen R, Orchard JW, Pluim BM, Raftery M, Budgett R, Engebretsen L. Br J Sports Med. 2016 Sep;50(17):1030-41. doi: 10.1136/bjsports-2016-096581.

How much is too much? (Part 2) International Olympic Committee consensus statement on load in sport and risk of illness

Schwellnus M, Soligard T, Alonso JM, Bahr R, Clarsen B, Dijkstra HP, Gabbett TJ, Gleeson M, Hägglund M, Hutchinson MR, Janse Van Rensburg C, Meeusen R0, Orchard JW, Pluim BM, Raftery M, Budgett R, Engebretsen L. Br J Sports Med. 2016 Sep;50(17):1043-52. doi: 10.1136/bjsports-2016-096572.

The International Olympic Committee organized an expert group to review the “evidence for the relationship of load—including rapid changes in training and competition load, competition calendar congestion, psychological load and travel—and health outcomes in sport.” Part 1 for risk of injury covers terminology and definitions, monitoring of load and injury, load and risk of injury in athletes, practical guidelines for load management, and research directions for load management in sport. Part 2 for risk of illness covers terminology and definitions, measures and monitoring, load and risk of illness in athletes, practical clinical guidelines, and suggested research.

Integrating Injury Prevention in Schools!

A School-Based Injury Prevention Program to Reduce Sport Injury Risk and Improve Healthy Outcomes in Youth: A Pilot Cluster-Randomized Controlled Trial

Richmond SA, Kang J, Doyle-Baker PK, Nettel-Aguirre A, & Emery CA.  Clin J Sport Med. 2016;26:291–298. doi: 10.1097/JSM.0000000000000261

Take Home Message: An injury prevention warm-up two to three times a week in a junior high school physical education class decreased injuries and improved overall fitness.

We have had multiple posts on Sports Med Res about the effectiveness of injury prevention programs for reducing the risk of injuries among high school and collegiate athletes.  Researchers have not evaluated the effectiveness of these programs in many younger groups and have not taken into consideration aerobic intensity.  The authors of this randomized trial wanted to evaluate the effectiveness of an injury prevention program in reducing injuries as well as improving body composition and fitness levels in a youth school-based population (11 to 15 year olds).

Hands off the Hands-free Ultrasound If You Are Looking for Deep Heating Effects

Comparison of Hands-free Ultrasound and Traditional Ultrasound for Therapeutic Treatment

Melanson H., Draper DO., Mitchell UH., Eggett DL. Athl Train Sports Health Care 2016;8(4):177-184

Take Home Message: A hands-free ultrasound unit at 1 MHz failed to increase the temperature deep in the gastrocnemius after 10 minutes.

Therapeutic ultrasound is an effective deep heating modality (heating to a depth of ~2 to 5 cm) when used properly. Traditional ultrasound treatments are labor intensive, time consuming, and prone to clinician error (e.g., treating too large an area, moving the sound head too fast). There is a hands-free ultrasound unit; however, there is little research whether the hands-free unit produces the same deep heating effects as traditional ultrasound. Therefore, the authors conducted a randomized cross-over experiment with 16 healthy participants (6 males and 10 females, age ~22 years, average gastrocnemius subcutaneous fat thickness ~0.85 cm) to determine whether the Rich-Mar AutoSound would be as effective as a traditional ultrasound at increasing the temperature of the gastrocnemius muscle during a 10-minute, 1 MHz, 1.0 W/cmtreatment.

Quick Clinical Model to Identify Chronic Ankle Instability

Comparison Between Single and Combined Clinical Postural Stability Tests in Individuals With and Without Chronic Ankle Instability

Ko J, Rosen AB, Brown CN. Clin J Sport Med 2016;0:1–6

Take Home Message: Clinicians may be able to use the single-leg hop test and Star Excursion Balance Test to identify people with chronic ankle instability.

There has been immense interest in trying to prevent or treat chronic ankle instability, which is characterized by recurrent episodes of giving way and functional limitations. However, the only measures that have demonstrated high reliability of identifying chronic ankle instability are self-reported questionnaires, and it is difficult to determine functional limitations without objective measures. Therefore, the authors assessed if clinical tests independently and/or in combination could accurately differentiate individuals with and without chronic ankle instability to determine which tests could best match self-report perception of function.
