Parents, Where are You Getting Your Concussion Information?

Knowledge assessment of sports-related concussion among parents of children aged 5 years to 15 years enrolled in recreational tackle football

Mannings C., Kalynych C., Joseph MM., Smotherman C., Kraemer DF. Journal of Trauma and Acute Care Surgery. 2014; 77(3) Supplement 1:S18-S22.
http://www.ncbi.nlm.nih.gov/pubmed/25153049                           

Take Home Message: Parents of young athletes (5 to 15 year olds) lack of knowledge regarding concussion definition, signs and symptoms, and mechanisms. We need to implement more concussion education programs for parents of young athletes.

Pediatric concussion care is challenging due to a lack of medical personnel at events and young athletes may not be able to articulate or recognize their concussion signs and symptoms. This leaves parents responsible for recognizing a concussion injury. However, we lack research regarding the knowledge of concussions among parents of youth recreation tackle football. Therefore, the purpose of this study was to determine parental knowledge concerning the definition as well as the signs and symptoms of concussion in young athletes (5 to 15 years old) who participate in recreational tackle football.

Performance May Not Mirror Patient-Reported Outcomes Following Autologous Chondrocyte Implantation

Patient-oriented and performance-based outcomes after knee autologous chondrocyte implantation: A timeline for the first year of recovery.

Howard JS, Mattacola CG, Mullineaux DR, English RA and Lattermann C. J Sport Rehabil. 2014 [Epub Ahead of Print].
http://dx.doi.org/10.1123/jsr.2013-0094

Take Home Message: Following autologous chondrocyte implantation (ACI), performance based and patient-reported outcomes can be valuable for measuring success. Patient-reported outcomes were better at all post-operative time points while performance-based measurements decreased for the first 6 months following ACI.

The success of autologous chondrocyte implantation (ACI), a common treatment for symptomatic articular cartilage defects, is normally measured through patient-reported outcomes. Despite this, performance-based metrics could also be used yet no one has recorded the timeline for recovery with patient-reported or performance-based measurements. A better understanding of the recovery timeline for both types of outcomes could help us optimize our rehab protocols and educate our patients about their anticipated recovery. Therefore, Howard and colleagues assessed performances-based and patient-reported changes in knee function over 1 year after ACI.

Statins: Lower Cholesterol and Improve Tendon Healing While You’re at it!

Statins Enhance Rotator Cuff Healing by Stimulating the COX2/PGE2/EP4 Pathway: An In Vivo and In Vitro Study

Dolkart O, Liron T, Chechik O, Somjen D, Brosh T, Maman E, Gabet Y.
Am J Sports Med. 2014 Sep 2. [Epub ahead of print]

Take Home Message: Statins enhance rotator cuff healing following repair through stimulation of the acute inflammatory phase. Statins may be a useful modality to improve tendon healing and reduce re-tear rates.

Rotator cuff repair failure (i.e., gap formation, incomplete healing) is common.  The mechanism by which poor healing occurs is multifactorial (for example, mechanical, biochemical). One contributing factor of insufficient healing may be a lack of inflammatory cells at the insertion site, which reduces the tendon’s natural reparative process.  The use of pharmaceuticals to control inflammation may improve tendon healing.  For example, statins, the popular lipid-lowering drugs, are suggested to modify inflammation.  Therefore, the objective of this study was to determine the effect of statins on tendon healing following rotator cuff repair in rats and on tenocyte (a type of cell in tendons) cultures in a petri dish.

Not So Competitive Return Rates to Activity Following ACL Reconstruction

Fifty-five percent return to competitive sports following anterior cruciate ligament reconstruction surgery: an updated systematic review and meta-analysis including aspects of physical functioning and contextual factors

Ardern CL, Taylor NF, Feller JA, & Webster KE. Br J Sports Med.  Published online first August 25, 2014. doi: 10.1136/bjsports-2013-093398 http://bjsm.bmj.com/content/early/2014/08/24/bjsports-2013-093398.short

Take Home Message:  Only 55% of athletes returned to competitive sport following anterior cruciate ligament (ACL) reconstruction.  The debate continues as to whether hamstring or patellar tendon autograft is better.  However, factors that may favor return to competitive sport include younger age, male gender, elite sport, and a positive psychological response.      

Return to sport participation following anterior cruciate ligament (ACL) reconstruction is often considered a measure of surgery success.  Unfortunately, we don’t have a good estimate of how often athletes successfully return to activity rates after an ACL reconstruction and which factors (individual and external) may affect return to activity.  Therefore, Ardern and colleagues conducted a meta-analysis to determine the return to sport rate after an ACL reconstruction and which factors favored returning to play.

Acute Gains in Motion After Single Bout of Stretching Predicts Short-Term Gains

Correlation between acute and short-term changes in flexibility using two stretching techniques

Beltrao NB., Ritti-Dias RM., Pitangui ACR., De Araujo RC. Int J Sports Med. 2014; ahead of print

Take Home Message: Acute changes in flexibility after either static or PNF stretching predict the gains in flexibility after a 7-day stretching program.

We often try to improve flexibility among our patients; but yet improved flexibility often depends on the type and duration of a stretching regimen and various patient characteristics. If we could predict gains in flexibility this would help us develop more individualized flexibility plans. One strategy could be to determine if a response to an acute bout of stretching could predict flexibility gains over time. Therefore, the purpose of this study was to determine whether increases in flexibility after a single session predicted increases in flexibility after a short-term stretching training program of static stretching or proprioceptive neuromuscular facilitation (PNF).

Can You Hear Me Now?

Is there sufficient evidence for tuning fork tests in diagnosing fractures? A systematic review

Mugunthan K, Doust J, Kurz B, and Glasziou P. BMJ Open. 2014. 4.

Take Home Message: The use of a tuning fork in ruling out fractures is not currently recommended due to low diagnostic accuracy. Little clinical standards, low study quality and small sample size limits the results therefore more standardization and training should be done to improve its clinical efficiency.

In some situations radiographic imaging is not readily available and clinicians must attempt to assess an injury with other tools such as a tuning fork. Unfortunately, the diagnostic accuracy of tuning forks is not known. Therefore, Mugunthan and colleagues completed a systematic review to determine the diagnostic accuracy of tuning forks for assessing fracture.
