Tissue Engineering for Meniscal Tears

OREF grant recipient seeks to preserve joint after treatment

Jay D. Lenn

When meniscal tears occur in the avascular region of the meniscus, treatment options are limited. Removing the damaged tissue (resection) is the most common treatment. Although the surgery relieves pain and restores a certain degree of function, it also alters the way mechanical loads are transferred across the joint and often contributes to articular degeneration in the joint.

Pathogenesis and Prevention of Posttraumatic Osteoarthritis After Intra-articular Fracture

Posttraumatic osteoarthritis (PTOA) occurs after traumatic injury to the joint. It is most common following injuries that disrupt the articular surface or lead to joint instability. The reported risk of PTOA following significant joint trauma is as high as 75%; articular fractures can increase the risk more than 20-fold. Despite recent advances in surgical management, the incidence of PTOA following intra-articular fractures has remained relatively unchanged over the last few decades. Pathogenesis of PTOA after intra-articular fracture is likely multifactorial and may be associated with acute cartilage injury as well as chronic joint overload secondary to instability, incongruity, and malalignment. Additional studies are needed to better elucidate how these factors contribute to the development of PTOA and to develop advanced treatment algorithms that consist of both acute biologic interventions targeted to decrease inflammation and cellular death in response to injury and improved surgical methods to restore stability, congruity, and alignment.

Guest Editorial: Plating of Distal Humerus Fractures

This special issue of Orthopaedic Knowledge Online Journal focuses on plating techniques for the open reduction and internal fixation of distal humerus fractures in adults. While variations in technique exist for any surgical procedure, two distinct approaches, namely 90–90 plating and parallel plating, have evolved over the past two decades as viable options for the surgical fixation of such fractures. Available evidence does not show a significant difference in the outcomes achieved with the two techniques. These articles offer two different perspectives on the treatment of distal humerus fractures, and are intended to help the treating surgeon recognize the similarities and differences between the techniques and avoid problems.

Arthroscopic Ankle Fusion: The Posterior Approach

Arthrodesis of the ankle is a well-established procedure for managing end-stage arthritis of the ankle. Because the most common cause of ankle arthritis is previous trauma, it often presents with compromised soft tissues. The evolution of arthroscopy has led to several arthroscopic techniques for ankle arthrodesis. The universal primary goal of these techniques is reliable fusion of the bones of the ankle with a reduced risk of complication. The posterior arthroscopic approach to ankle fusion presented in this article has several well-defined advantages. It offers a wide view and working area while allowing for maximal compression of the talar surface onto the tibial dome with two parallel screws. The position of the foot is well controlled through the direct visualization of hindfoot alignment. From the time of its introduction into our practice, the posterior arthroscopic approach to ankle fusion has proven to be a safe and reliable treatment option.
