The mission of SMR is to objectively summarize and describe the clinical relevance of research articles related to basic science, translational research, and clinical research that may be relevant to students and professionals interested in sports medicine. Furthermore, SMR aims to provide a forum for clinicians, researchers, and students in sports medicine-related fields to discuss the clinical relevance of new research.
Partial meniscectomy is commonly performed in symptomatic knees. It is a minimally invasive surgery that requires a relatively short recovery time, resulting in less missed activity. Meniscectomy is a recognized risk factor for the development of tibiofemoral osteoarthritis (OA). However, it remains unclear whether risk of patellofemoral OA is elevated as well. The purpose of this cross-sectional study was to evaluate the patellofemoral and tibiofemoral cartilage using magnetic resonance (MR........ Read more »

It has been suggested for years that knee injuries are a risk factor for developing knee osteoarthritis (OA). Unfortunately, most studies are inconsistent in how previous knee injuries are defined (e.g., type of injury, severity of injury) and this has made it challenging to accurately determine the true risk of developing knee OA after sustaining an injury. Therefore, Muthuri et al performed a meta-analysis of 24 observational studies to quantify the association between knee OA and history of k........ Read more »

Evaluations of anterior cruciate ligament (ACL) tears include a battery of clinical tests, including Lachman’s, anterior drawer, and pivot shift test. The pivot shift test is often cited as being able to assess the integrity of the ACL due to its ability to test both the anterior translation and rotational stability of the knee, as well as its ability to reproduce the common symptoms of “giving way.” However, it is difficult to objectively measure the results of this test. T........ Read more »

There are a number of symptoms that are associated with a mild traumatic brain injury (mTBI); however, neuropsychological testing and conventional neuroimaging techniques (e.g., standard magnetic resonance [MR] imaging, computed tomography [CT] scans) are not sensitive enough to detect subtle changes. There have been advances in the neuroimaging field that allow a more sensitive and specific detection of mTBI using functional magnetic resonance imaging (fMRI). This study used resting-state fMRI ........ Read more »

A recent study demonstrated that athletes with patellar tendinopathy had less ankle dorsiflexion but it was unclear if limited dorsiflexion causes patellar tendinopathy or if it was a consequence of the patellar tendinopathy. To determine if limited ankle dorsiflexion contributed to the onset of patellar tendinopathy, Backman et al conducted a 1-year prospective study to examine if reduced ankle dorsiflexion range of motion increases the risk of developing patellar tendinopathy among 75 Swedish ........

Su et al used 10 cadaver shoulders to examine the amount of humeral head displacement following varying degrees of anterosuperior (i.e., supraspintatus subscapularis) and posterior/superior (i.e., supraspintus infraspinatus) rotator cuff tears when loaded in a posterosuperior direction. ...

Ankle injuries are common in high school sports and it has been estimated that 24% of all ankle injuries among high school athletes are sustained by football players. Lace-up braces are commonly used with the goal of preventing ankle injuries. Unfortunately, there is limited data about the efficacy of lace-up braces among adolescent football players. Therefore, McGuine et al assessed whether using a lace-up ankle brace reduced the number and severity of acute first-time and recurrent ankle injur........ Read more »

This past week the new MacArthur fellowships, popularly referred to as the “genius grants” were announced and among the recipients was Kevin Guskiewicz. Dr. Guskiewicz has “made major advances in the diagnosis, treatment, and prevention of sports-related concussions.” Unlike many funding opportunities this award is unique in that you must be anonymously nominated, show exceptional merit and promise in your work, and the award money can be used in any way to advance the in........

Efficacy of Treatment of Trochanteric Bursitis: A Systematic Review
Lustenberger DP, Ng VY, Thomas M. Best TM, Ellis TJ. Clin J Sport Med. 2011 Sept; Vol 21(5), 447-453.
Trochanteric bursitis presents as lateral hip pain and can be a very frustrating condition to treat. To date, there have been no systematic reviews of the literature comparing the various treatment modalities used. In this systematic review, the authors attempt to evaluate the e........ Read more »
