Thomas Gus Almonroeder, Thomas Kernozek, Stephen Cobb, Brooke Slavens, Jinsung Wang, Wendy Huddleston
Study Design Cross-sectional study. Background The drop vertical jump task is commonly used in anterior cruciate ligament injury risk screening; however, the predictive validity is limited. Part of the limited predictive validity may be because the drop vertical jump task does not impose cognitive demands that reflect sports participation. Objectives To investigate the influence of additional cognitive demands on lower extremity mechanics during execution of the drop vertical jump task. Methods Twenty uninjured females (ages 18-25 years old) were required to perform the standard drop vertical jump task, as well as drop vertical jumps which included additional cognitive demands...

Study Design Systematic review. Background Therapeutic exercise is commonly used to treat individuals with knee disorders, but dosing parameters for optimal outcomes are unclear. Large variations exist in exercise prescription, and research related to specific dosing variables for knee osteoarthritis, patellar tendinopathy and patellofemoral pain syndrome is sparse. Objectives To identify specific doses of exercise related to improved outcomes of pain and function in individuals with common knee disorders, categorized by effect size...

Mechanically assisted crevice corrosion (MACC) is a mechanism for trunnion damage in total hip arthroplasties (THAs). Retrieval studies have shown reduced MACC-related damage for ceramic heads compared with cobalt-chromium (CoCr) heads. We propose that ceramic heads demonstrate fretting at higher cyclic compressive loads than CoCr heads on titanium alloy trunnions in a simulated corrosion model. A closed electrochemical chamber was used to measure fretting current onset loads for two modern titanium alloy trunnions (Zimmer 12/14 and Stryker V-40) in which trunnion failure has been reported...

Study Design Systematic literature review with meta-analysis. Background Management of patellofemoral pain (PFP) may include the utilization of manual therapy (MT) techniques to the patellofemoral joint, surrounding soft tissues, and/or lumbospelvic region. Objectives To determine the effectiveness of MT, either used alone or as an adjunct intervention, compared to standard treatment or sham, for reducing pain and improving self-report function in individuals with PFP. Methods An electronic literature search (PubMed, OVID, CENTRAL, and CINAHL databases) was conducted for studies investigating MT for individuals with PFP...

Study Design Controlled laboratory study. Background Inclusion of specific exercises in rehabilitation after knee injury is currently expert-based as a thorough description of the knee contact forces during different exercises is lacking. Objective To quantify knee loading during frequently used activities such as squat, lunges, single leg hop, walking stairs, standing up and gait to grade knee joint loading during these activities. Methods 3D-motion analysis data of 15 healthy adults were acquired during 9 standardized activities used in rehabilitation...

A 20-year-old military cadet injured his left shoulder after landing in an abducted and externally rotated arm position while participating in a mandatory obstacle course. Following examination, the individual was taken to the emergency department, where radiographs confirmed an anterior dislocation of the glenohumeral joint and a large Hill-Sachs lesion wedged on the glenoid. Results of noncontrast magnetic resonance imaging and a computed tomography scan confirmed the presence of a large Hill-Sachs lesion...

A 15-year-old baseball pitcher presented to physical therapy with a 1-week history of acute right shoulder pain experienced during the acceleration phase of throwing. The week after physical therapy evaluation, the patient returned with radiographs and magnetic resonance imaging results that revealed lateral physeal widening with adjacent edema. Additionally, a nondisplaced labral tear was noted. In this case, imaging was necessary for an accurate diagnosis of lateral physeal widening, commonly referred to as "Little League shoulder...

Pain in the front of your knee or under your kneecap is often called patellofemoral pain. The pain may be a nagging ache or an occasional sharp twinge. Because the pain is around the front of your knee, treatment has traditionally focused on the knee itself. However, recent evidence suggests that strengthening your hip muscles can also help by decreasing the stress in your knee. A study published in the January 2018 issue of JOSPT provides new insights and evidence-based suggestions on how to strengthen your entire leg to decrease your knee pain and help you return to full activity...

As a potential high-yield tool for disseminating information that can reach many people, social media is transforming how clinicians, the public, and policy makers are educated and find new knowledge associated with research-related information. Social media is available to all who access the internet, reducing selected barriers to acquiring original source documents such as journal articles or books and potentially improving implementation-the process of formulating a conclusion and moving on that decision...

The etiology of patellofemoral pain (PFP) is thought to include both local factors (those near the patellofemoral joint and surrounding tissues) and nonlocal factors (those related to the mechanics of the distal and proximal joints). Traditionally, PFP rehabilitation protocols have focused on local factors. Strengthening of the hip may reduce excessive hip adduction and medial rotation during weightbearing activities and so decrease patellofemoral joint stresses. However, while previous studies indicate that including hip strengthening may lessen the intensity of PFP, the effects on strength and activity remain uncertain...

Study Design Cohort study. Background Multiple operational definitions of injury exist in dance research. The influence that these different injury definitions have on epidemiological estimations of injury burden among dancers warrants investigation. Objective To describe the influence of injury definition on injury prevalence, incidence, and severity in pre-professional ballet and contemporary dancers. Methods Dancers registered in full-time pre-professional ballet [n=85, 77 females, median age 15-years (range 11-19)] and contemporary [n=60, 58 females, median age 19-years (range 17-30)] training completed weekly online questionnaires (modified Oslo Sports Trauma Research Centre's Questionnaire on Health Problems) using three injury definitions: (1) time-loss (unable to complete ≥1 class/rehearsal/performance ≥1 day(s) beyond onset); (2) medical attention; (3) any complaint...

Study Design Clinical measurement study. Background Achilles tendinopathy is a prevalent sport-related injury. The Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire is a widely-used patient-reported outcome to assess the severity of symptoms for this injury. Objective To adapt the VISA-A questionnaire into Spanish and to assess its psychometric properties. Methods Cross-cultural adaptation was conducted according to recommended guidelines. The Spanish VISA-A (VISA-A-Sp) questionnaire was administered to 210 subjects: 70 healthy students, 70 active at risk subjects (participating in running and jumping) and 70 patients with Achilles tendinopathy diagnosis...

A 15-year-old adolescent boy was referred by an orthopaedic surgeon for treatment of right gluteal and thigh pain. Following treatment that reduced his pain, he experienced acute onset of bilateral radiculopathy. He was referred back to the physician, who ordered radiographs and magnetic resonance imaging, which identified a grade IV isthmic spondylolisthesis at the L5-S1 level.
