Cartilage Regeneration
Rocky S. Tuan, PhD, Abstract Cartilage damaged by trauma has a limited capacity to regenerate. Current methods of managing small chondral defects include palliative treatment with arthroscopic débridement and lavage, reparative treatment with marrow-stimulation techniques (eg, microfracture), and restorative treatment, including osteochondral grafting and autologous chondrocyte implantation. Larger defects are managed with osteochondral allograft or […]
MRI Techniques: A Review and Update for the Orthopaedic Surgeon
Katherine G. Hartley J Am Acad Orthop Surg December 2012 ; 20 Abstract MRI plays a critical role in all orthopaedic practices. A basic working knowledge of the most commonly used pulse sequences in musculoskeletal imaging and the appearance of normal tissues on those sequences is critical to confident MRI interpretation. The orthopaedic surgeon should […]
Bone Morphogenetic Protein in Spine Surgery: Current and Future Uses
J Am Acad Orthop Surg. September 2012 ; 20 (9) Jesse Even, MD, Mark Eskander, MD and James Kang, MD Abstract The clinical use of bone morphogenetic protein (BMP) in spinal fusion surgery has recently become controversial. After its approval by the US FDA in July 2002, BMP was adopted by many spine surgeons as […]
Implantable Sensor Technology: From Research to Clinical Practice
J Am Acad Orthop Surg June 2012 vol. 20 no. 6 Eric H. Ledet Abstract For decades, implantable sensors have been used in research to provide comprehensive understanding of the biomechanics of the human musculoskeletal system. These complex sensor systems have improved our understanding of the in vivo environment by yielding in vivo measurements of […]
Biomechanical Testing of Fracture Fixation Constructs: Variability, Validity, and Clinical Applicability
Michael J. Gardner J Am Acad Orthop Surg February 2012 ; 20 Abstract Biomechanical testing of fracture fixation implants is crucial in preclinical evaluation and in comparing new devices with standard devices. Many variables must be considered when planning and implementing a biomechanical in vitro experiment. The type of test selected (eg, load-to-failure, stiffness, cyclic […]
Nerve Conduits for Nerve Repair or Reconstruction
Nicole Deal J Am Acad Orthop Surg February 2012 ; 20 Abstract Advances in treating peripheral nerve lesions have resulted from research in nerve regeneration and the use biomaterials as well as synthetic materials. When direct tensionless repair of peripheral nerve lesions is not possible, nerve conduits may be used to bridge digital sensory nerve […]
The Effect of Drill Bit, Pin, and Wire Tip Design on Drilling
NULL Bryce M. Fincham, Todd Jaeblon J Am Acad Orthop Surg September 2011 ; 19: Abstract Successful penetration of bone is dependent on several factors, including bone quality, drill bit and pin design, and drilling technique. Wires are also used in bone drilling, and the tip configuration can affect the efficiency of bone penetration. Incorrect […]
Tissue Engineering Solutions for Tendon Repair
J Am Acad Orthop Surg, Vol 19, No 3, March 2011 MaCalus V. Hogan, MD, Namory Bagayoko, MD, Roshan James, MS, Trevor Starnes, MD, PhD, Adam Katz, MD and A. Bobby Chhabra, MD Tendon injuries range from acute traumatic ruptures and lacerations to chronic overuse injuries, such as tendinosis. Even with improved nonsurgical, surgical, and […]

Randomized Clinical Trials in Orthopaedic Surgery: Strategies to Improve Quantity and Quality
NULL S. Samuel Bederman, MD, PhD, FRCSC, Josie Chundamala, MA and James G. Wright, MD, MPH, FRCSC J Am Acad Orthop Surg, Vol 18, No 8, August 2010 Randomized clinical trials (RCTs) generally provide the highest quality and least biased evidence for treatment effectiveness. Relatively few high-quality RCTs have been published in the orthopaedic literature. […]
