Risk Factors for Medial Tibial Stress Syndrome and Tibial Stress Fractures in Runners

by Jill R. Crosson DO, MBA in Sports Medicine Research (SMR): In the Lab & In the Field

Medial Tibial Stress Syndrome (MTSS), also known as ‘shin splints,’ is commonly seen in runners and can be a very frustrating and nagging injury. Tibial stress fractures (SF) are another significant injury that can potentially force athletes to take long periods of rest. Despite the high frequency of MTSS and the implications of SF, it is unclear what risk factors may be related to these conditions. Therefore, the authors of this study wanted to identify the incidence and also estab........ Read more »

Failed Healing of Rotator Cuff Repairs Relates to Degradative Enzymes Levels Prior to Repair

by Katie Reuther in Sports Medicine Research (SMR): In the Lab & In the Field

Rotator cuff tears are a common cause of shoulder pain and disability. Surgical repair is often recommended in an attempt to reduce pain and restore function. Unfortunately, recurrent defects often persist (20-94% of cases) due to failure of the rotator cuff to heal. Several biologic and environmental factors have been implicated as important to tendon healing and remodeling; therefore, their presence (or lack thereof) may be critical when repairing torn rotator cuff tendons. The objective o........ Read more »

Return to High School- and College-Level Football After Anterior Cruciate Ligament Reconstruction

by Kathleen White in Sports Medicine Research (SMR): In the Lab & In the Field

Anterior cruciate ligament (ACL) injuries are common among young football players. Surgical reconstruction is currently the most common intervention to facilitate return to play, however not all athletes are successful. Unfortunately, there is a lack of data regarding how many football players return to play and what factors may increase the risk of a player not being able to return to play. The purpose of this study was to determine the percentage of high school and college-level football playe........ Read more »

Implications for Dexamethasone Treatment of Tendon Injury

by Sarah Ilkhani-Pour in Sports Medicine Research (SMR): In the Lab & In the Field

Tendinopathy is a clinical diagnosis characterized by focal tenderness, activity-related pain, weakness, and increased tendon size. Unlike the commonly used term “tendinitis” suggests, inflammation is not normally seen in the late stages of tendinopathy but may be present in early stages. Clinically, despite lack of evidence of inflammation in chronic tendinopathy, prescription of glucocorticoids, such as Dexamethasone, is often used as a quick-fix to reduce pain and “inflamm........

Adaptations of Shoulder Joint Stiffness may Lead to Increased Muscle Efficiency and Neuromuscular Control

by Jane McDevitt. in Sports Medicine Research (SMR): In the Lab & In the Field

During overhead throwing energy must be absorbed and distributed across soft tissues (i.e., musculotendinous structures, joint capsule/ligaments) within a limited range of motion to minimize the risk of injuries. This is primarily accomplished by the interaction between the nervous and musculoskeletal systems that influences shoulder stiffness. Active stiffness, which combines passive (e.g., capsule, ligament, and tendons) with dynamic components (e.g., muscles co-contraction and reflex response........ 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 »

The Effectiveness of “The 11” in Preventing Injuries among Male Amateur Soccer Players

by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field

Incidence of injuries in soccer is among the highest of all team sports. FIFA developed an exercise program, called the 11, that focuses on injury prevention. This program has been tested among younger soccer players but not among male adults, which represents a large number of soccer players. Therefore, van Beijsterveldt and colleagues completed a cluster-randomized controlled trial to investigate the effectiveness of The 11 program to reduce the incidence and severity of injuries among adult m........

Do NSAID’s Delay Healing in Stress Fractures?

by Kris Fayock in Sports Medicine Research (SMR): In the Lab & In the Field

Non-steroidal anti-inflammatory drugs (NSAIDs) are a commonly used medication for pain related to musculoskeletal injuries that can be obtained both over the counter and with a prescription. They act by inhibiting the effects of cyclooxygenase (COX) enzymes, which play a role in bone biology, specifically bone resorption by COX-2. Stress fractures are common injuries that affect many people of all ages and level of activity. There are studies that show negative effects of NSAIDs on complete f........ Read more »

Survival of the ACL Graft and the Contralateral ACL at a Minimum of 15 Years

by Andrew Lynch in Sports Medicine Research (SMR): In the Lab & In the Field

Anterior cruciate ligament injury is devastating to the athletic career of an athlete, but it is also potentially only the beginning of knee problems for an athlete. ACL reconstruction likely follows, which can restore static stability (but not prevent the development of arthritis or guarantee a return to sports), but we know that there is at least some risk for suffering a graft injury or a contralateral ACL injury. However, like many aspects of function after ACL injury, we don’t have s........ Read more »

Calcium Phosphate Soaking to Improve ACL Graft Tendon-Bone Healing?

by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field

Anterior cruciate ligament (ACL) reconstruction is performed regularly in the orthopedic world with relatively favorable results. While the selection of a hamstring autograft allows for fewer issues at the harvest site than the patellar tendon autograft, the problem that arises is the lack of bone block to assure graft fixation and possible widening of bone tunnels over time. The purpose of this randomized controlled trial was to assess the effectiveness of calcium phosphate (CaP) graft hybrid........ Read more »

Are Your Parents Cramping Your Style?

by Jane McDevitt in Sports Medicine Research (SMR): In the Lab & In the Field

Previous research has shown that variants, like single nucleotide polymorphisms (SNPs), within collagen genes (e.g., COL5A1, COL3A1, COL6A1, and COL12A1) can influence the structure and function of different collagen fibers. Furthermore, altered collagen fibers may be a predisposing factor to exercise-associated muscle cramping, however, research has yet to examine if genetic variants in these collagen genes are associated with a history of exercise-associated muscle cramping among runners. Ther........ Read more »

Factors Associated with Patellofemoral Pain Syndrome

by Hallie Labrador in Sports Medicine Research (SMR): In the Lab & In the Field

Patellofemoral pain syndrome (PFPS) is a very common diagnosis, making up about 25% of all running injuries. It can also be a very frustrating diagnosis for both patients and clinicians. Whereas short-term treatments can be successful in alleviating symptoms, long-term results are variable, and there is no definitive operative management for PFPS. Several studies have examined risk factors for the development of PFPS with the goal of directing treatments at modifiable factors. The purpose of thi........ Read more »

Quadriceps Function in Braced ACL Reconstructed Patients

by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field

Following anterior cruciate ligament (ACL) reconstruction surgeries many patients wear a variety of knee braces with the intent to increase joint stability and prevent further injury. However, little is known about the neuromuscular effects of these braces during exercise among patients with ACL reconstructions. Therefore, Davis and colleagues completed a crossover study to compare quadriceps muscle activation (maximal contraction and central activation ratio [CAR]) among 14 patients with ACL re........

Can the Sleeper Stretch Increase Range of Motion and the Sub-Acromial Space?

by Stephen Thomas in Sports Medicine Research (SMR): In the Lab & In the Field

It is well known that overhead athletes develop a loss of internal rotation (IR; also called glenohumeral internal rotation deficit or GIRD) and a gain of external rotation (ER). Recently, it has been demonstrated that baseball players with GIRD are more likely to develop shoulder injuries. It has been suggested that GIRD is caused by a tight posterior capsule and during ER the tight capsule may alter the arthrokinematics of the shoulder by moving the head of the humerus in a posterior-superio........

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 »

The Accuracy of Hip Special Tests

by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field

In recent years, there has been a significant increase in the number of diagnosed hip pathologies due to greater attention to this area. “Chronic groin pain” is no longer an accepted diagnosis for athletic injuries. Therefore, we need a closer look at the accuracy of hip special tests for athletic injuries to help determine which special tests can help us make differential diagnoses. The purpose of this systematic review was to analyze the literature on hip special tests to determ........ Read more »

Re-evaluating RICE for Ankle Sprains

by Jane McDevitt in Sports Medicine Research (SMR): In the Lab & In the Field

Ankle sprains are one of the most common musculoskeletal injuries. Rest, ice, compression, elevation (RICE) is an easy and popular therapy option in the acute stage of an ankle sprain, however, there is a lack of evidence-based research supporting this treatment. Therefore, the objective of this study was to utilize a systematic review to determine the effectiveness of using RICE therapy within 72 hours after an ankle sprain.... Read more »

Balance and Neurocognitive Deficits in Non-Concussed Athletes

by Stephen Stache in Sports Medicine Research (SMR): In the Lab & In the Field

Post-injury management of sports-related concussion has become increasingly dependent on the results from neurocognitive assessments, which rely on both subjective and objective data, including Balance Error Scoring System (BESS), the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT), and the Postconcussion Symptom Scale. A recent study examining high school athletes 2 days following a concussion found that even in the non-concussion control group, 30% of the athletes had sign........ Read more »

Kinesio Tape and Cervical Manipulation Help Decrease Mechanical Neck Pain

by Kyle Harris in Sports Medicine Research (SMR): In the Lab & In the Field

Mechanical neck pain is a common ailment which can affect as much as 33% of the population. While manual therapy is often performed, a gold standard for managing mechanical neck pain has yet to be determined. Also supported for managing mechanical neck pain is the use of Kinesio Tape, although there is limited evidence to support this. Therefore, Saavedra-Hernández and colleagues completed a randomized clinical trial comparing manual therapy to Kinesio Taping.... Read more »

Injuries in High School Softball and Baseball Players

by Laura McDonald in Sports Medicine Research (SMR): In the Lab & In the Field

Over the last ten years, participation rates have increased in baseball and softball (3.9% and 8.4% at the interscholastic level, respectively). Despite this rise in popularity, a dearth of knowledge exists concerning the incidence of injuries sustained by high school baseball and softball players. Therefore, the authors conducted a prospective cohort study of high school athletes (247 athletes; 103 female, 144 male) to determine initial and subsequent injury rates; compare injury rates between ........
