Delayed ACL Reconstructions may be Associated with More Severe Meniscal and Chondral Lesions
by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field
Anterior cruciate ligament (ACL) ruptures often coincide with meniscal and cartilaginous injuries. These ruptures are generally treated with surgical reconstruction or non-surgical treatment. Patients who chose to delay surgical treatment may be at greater risk for increasing the severity of the associated injuries; however, this has not been demonstrated in the literature. Therefore, Fok and Yau completed a retrospective, comparative study investigating (1) if delaying ACL reconstruction is ass........ Read more »

New Evidence Supporting ACL Injury Prevention Warm-up Programs
by Stephen Stache, MD and Marc I. Harwood, MD in Sports Medicine Research (SMR): In the Lab & In the Field
Medications that improve the transmission of dopamine, a neurotransmitter, have been shown to improve functional outcomes in animal models of concussion. Amantadine, a dopaminergic agent, has recently been shown through preliminary research and anecdotal evidence to improve post-concussion cognitive function and symptoms such as attention, concentration, impulsivity, and fatigue. This retrospective study by Reddy, et al. examined the influence of amantadine on the improvement of cognitive defi........ Read more »

Effect of Inspiratory Muscle Training on Exercise Tolerance in Asthmatic Individuals
by Jeffrey B. Driban in Sports Medicine Research (SMR): In the Lab & In the Field
Patients with asthma place a greater demand on their inspiratory muscles, particularly during exercise. The greater workload may increase the risk of fatigue of the inspiratory muscles and therefore exacerbate dyspnea (shortness of breath) and reduce exercise tolerance. It has been hypothesized that strength training the inspiratory muscles in patients with asthma may help decrease the intensity of dyspnea and improve exercise tolerance. Therefore, Turner et al. performed a matched double-blind ........ Read more »

Knee Injuries and Knee Osteoarthritis: A Meta-analysis
by Jeffrey B. Driban in Sports Medicine Research (SMR): In the Lab & In the Field
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 »

Exercises Which Target Specific Hamstring Muscle Groups
by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field
With knee injuries, such as anterior cruciate ligament ruptures, being increasingly seen in sports, more and more emphasis has been placed on prophylactic exercises to reduce the risk of injury. Unfortunately, little is known about how different exercises challenge the hamstring muscles, which may be a key muscle group to optimize in prophylactic or rehabilitation programs. Therefore, Zebis and colleagues evaluated the levels of medial and lateral hamstring activation during selected exercises t........ Read more »

Adding Echocardiography to Pre-participation Screening
by Kris Fayock, MD and Marc Harwood, MD in Sports Medicine Research (SMR): In the Lab & In the Field
One of the main goals of pre-participation screening (PPS) is to identify unknown cardiac alterations in asymptomatic athletes with the intent to prevent sudden death in athletes. In Italy, it is mandatory by law that all children entering competitive activity must receive screening that includes physical examination and electrocardiogram (ECG), which is usually first done between the ages of 8 to 12 years of age. This mandatory screening has been shown to be effective in preventing sudden car........ Read more »

Biomarkers in Olympic Boxing: Diagnosis and Effects of Repetitive Head Trauma
by Jane McDevitt in Sports Medicine Research (SMR): In the Lab & In the Field
It has been shown that there are deleterious acute and long-term effects (e.g., chronic traumatic brain injury) in the brain among boxing athletes. Currently, there are no objective measures sensitive enough to diagnosis a concussion or monitor the long-term effects from head impacts (e.g., neurofibrillary tangles, amyloid plaques). Therefore the purpose of this study was to evaluate the relation between cerebral spinal fluid biomarkers (an objective measure that marks the state of a biological ........ Read more »

Head Case: What Role does Age and Gender Play Following a Concussion?
by Mark Rice in Sports Medicine Research (SMR): In the Lab & In the Field
There is no question that the topic of concussions is currently at the forefront of sports medicine. As with any injury, a structured approach must be taken regarding recognition, recovery and return to play. That said, our follow-up and treatment of concussions may need to take into account not only the athlete's age, but their gender as well. The purpose of this study was to examine how sex and age may affect post-concussion symptom reporting, postural stability and neurocognitive testi........ Read more »

Low Range of Ankle Dorsiflexion Predisposes Basketball Players to Patellar Tendinopathy
by Jeffrey B. Driban in Sports Medicine Research (SMR): In the Lab & In the Field
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 ........

New Evidence Supporting ACL Injury Prevention Warm-up Programs
by Christian Glaser in Sports Medicine Research (SMR): In the Lab & In the Field
Soccer is a popular sport throughout the world; however, female soccer athletes are much more prone to anterior cruciate ligament (ACL) injury than their male counterparts. One theory why female athletes are more prone to ACL injuries involves the different firing patterns of the muscles in the lower extremity in women compared to men, which leads to increased valgus load at the knee in females. Considering this hypothesis, is there a short, effective, and applicable intervention that could be........ Read more »

Patellar Tendon versus Hamstring Autografts: 11-year Follow-Up of a Randomized Clinical Trial
by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field
The goals of anterior cruciate ligament (ACL) reconstruction surgery are to decrease symptoms, increase function, and to return to pre-injury activity status. There are numerous techniques and grafts utilized for ACL reconstruction, including autografts or allografts. Autografts are frequently selected, and can consist of patellar tendon (PT) or semitendinosus and gracilis (STG) tendons. Currently, there is no consensus as to which graft is the best option for optimal outcomes. Therefore, th........ Read more »
