Bioelectrical Activity of Vastus Medialis and Rectus Femoris Muscles in Recreational Runners with Anterior Knee Pain.

J Hum Kinet 2019 Mar 27;66:81-88. Epub 2019 Mar 27.

Medical University of Lublin, Lublin, Poland.

Patellofemoral pain syndrome (PFPS), the most common source of knee pain among physically active individuals, is defined as anterior knee pain involving the patella and retinaculum that excludes other intraarticular and peri-patellar pathology. Differences in the activation and endurance of the quadriceps components, causing an imbalance in the forces controlling patellar tracking during flexion and extension in the knee joint, appear to be the most commonly reported risk factors for PFPS. The aim of this study was to determine the differences in bioelectric activity of vastus medialis and rectus femoris muscles during half knee bend position in runners with PFPS. Read More

Sex Differences in Common Sports-Related Injuries.

NASN Sch Nurse 2019 Mar 28:1942602X19840809. Epub 2019 Mar 28.

Clinical Research Coordinator Brigham and Women's Hospital Department of Women's Sports Medicine.

Sex plays a role in mediating different susceptibilities and outcomes of disease and injury. Sports injuries are included in this phenomenon, as recent research demonstrates that males and females show differences in incidences of varying injuries, presentations of injury, and treatment outcomes. Incidence of certain sports injuries like anterior cruciate ligament injury or patellofemoral pain syndrome may vary widely between male and female athletes, with female athletes being more susceptible to anterior cruciate ligament injury and patellofemoral pain syndrome.

Braces and splints can immobilize and protect joints, reduce pain, decrease swelling, and facilitate healing of acute injuries. They are also used for injury prevention and chronic pain reduction, and to alter the function of a joint. The medial unloading (valgus) knee brace is an option for patients with medial knee osteoarthritis, but evidence of long-term benefit is limited. Read More

A New Technique for Distalization of the Tibial Tubercle That Allows Preservation of the Proximal Buttress.

Orthop J Sports Med 2018 Sep 25;6(9):2325967118798621. Epub 2018 Sep 25.

Center for Regenerative Medicine and Cartilage Repair Center, Brigham and Women's Hospital, Boston, Massachusetts, USA.

Background: Tibial tubercle osteotomy (TTO) is a treatment option for patients with patellofemoral instability and chondrosis. Occasionally, these patients also present with patella alta, and distalization of the tibial tubercle is desirable. Free distal transfer of the tubercle, however, can compromise mechanical stability of the osteotomy construct, leading to loss of fixation. Read More
