High Interspecimen Variability in Engagement of the Anterolateral Ligament: An In Vitro Cadaveric Study

Anterolateral ligament (ALL) reconstruction as an adjunct to anterior cruciate ligament (ACL) reconstruction remains a subject of clinical debate. This uncertainty may be driven in part by a lack of knowledge regarding where, within the range of knee motion, the ALL begins to carry force (engages).

Free Vascularized Fibular Grafting Improves Vascularity Compared With Core Decompression in Femoral Head Osteonecrosis: A Randomized Clinical Trial

Management of osteonecrosis of the femoral head remains challenging. Core decompression and free vascularized fibular grafting are commonly used surgical procedures for treatment of osteonecrosis of the femoral head. Few studies, however, have compared these two procedures in a randomized controlled study, in terms of improved vascularity of the femoral head, progression of disease, or hip scores.

Combined Administration of ASCs and BMP-12 Promotes an M2 Macrophage Phenotype and Enhances Tendon Healing

Outcomes after intrasynovial tendon repair are highly variable. An intense inflammatory cascade followed by a delayed healing response can cause adhesion formation and repair-site failure that severely impair the function of repaired digits. No effective remedies exist to fully address these issues. Cell- and growth factor-based therapies have been shown to modulate inflammation and improve cell proliferation and matrix synthesis and therefore are promising treatment approaches for intrasynovial tendon repair.

Knee Abduction Affects Greater Magnitude of Change in ACL and MCL Strains Than Matched Internal Tibial Rotation In Vitro

28th April 2017, Symposium: Improving Care for Patients With ACL Injuries: A Team Approach

Anterior cruciate ligament (ACL) injures incur over USD 2 billion in annual medical costs and prevention has become a topic of interest in biomechanics. However, literature conflicts persist over how knee rotations contribute to ACL strain and ligament injury. To maximize the efficacy of ACL injury prevention, the effects of underlying mechanics need to be better understood.

Variations in Knee Kinematics After ACL Injury and After Reconstruction Are Correlated With Bone Shape Differences

27th April 2017, Symposium: Improving Care for Patients With ACL Injuries: A Team Approach

The factors that contribute to the abnormal knee kinematics after anterior cruciate ligament (ACL) injury and ACL reconstruction remain unclear. Bone shape has been implicated in the development of hip and knee osteoarthritis, although there is little knowledge about the effects of bone shape on knee kinematics after ACL injury and after ACL reconstruction.

What Demographic and Clinical Characteristics Correlate With Expectations With Trapeziometacarpal Arthritis?

Lana Kang MD, MSc, Joseph Nguyen MPH, Sohaib Z. Hashmi MD, Steve K. Lee MD, Andrew J. Weiland MD, Carol A. Mancuso MD
19th April 2017, Clinical Research

Pretreatment variables have been shown to be associated with the fulfillment of patient expectations, yet in treating thumb trapeziometacarpal osteoarthritis (OA) it remains unclear how patient expectations correlate with the effectiveness of treatment. An increased understanding of the variables that affect patient expectations enables tailored patient education and patient-provider communication.
