Recent renewed interest in the anatomy of the anterolateral complex of the knee, combined with concern regarding persistent instability after anterior cruciate ligament reconstruction, has led to an expansion of the literature on the biomechanics of many structures of the anterolateral complex of […]
Rotational instability of the knee in the presence of intact cruciate and collateral ligaments is a complex clinical problem to accurately diagnose and treat. Although advances in anatomic and biomechanical understanding of the knee have led to improved treatment of ligament injuries, there is still a subset of patients who present with symptoms of […]
Few studies have reported on the incidence, injury mechanisms, ligament injury patterns, and associated injuries of knee dislocations. Most studies are retrospective in nature, and few patients are included. The incidence of these injuries is reported to be between 0.02% and 0.2% of all orthopaedic injuries. There is […]
It is not yet clear whether current and emerging biologic strategies to treat musculoskeletal injuries will provide tangible benefits to patients . Platelet-rich plasma (PRP) is used widely despite a lack of evidence supporting its efficacy. Enthusiasm for mesenchymal stem cell (MSC)-based therapies is reflected by the prodigious number […]
Complete radial meniscus tears constitute a unique subset of meniscus injuries, resulting in disruption of the circumferential fibers and compromising their ability to with-stand hoop stresses. This results in decreased contact area and increased tibiofemoral contact pressure, which can lead to the onset of an accelerated joint degenerative […]
Increased attention has been directed toward the identification and treatment of concomitant knee injuries associated with anterior cruciate ligament (ACL) tears to best restore knee biomechanics and function. Studies have reported that 43% of patients with ACL tears have concomitant lateral or medial meniscal tears. Meniscocapsular tears of […]
Cell-therapy has been promoted among the therapeutic arsenal that can aid in 6 bone formation and remodeling, in early stages of osteonecrosis of the femoral head (ONFH). The purpose of this systematic review was to assess the evidence supporting the: (1)clinical efficacy; (2)structural modifying effect; as evaluated radiographically (3) revision rates; and (4)safety of […]
Menisci are crescent-shaped, fibrocartilaginous wedges that play an important role in complex knee mechanics and function. The menisci are primarily responsible for distributing loads through the tibiofemoral joint, joint stabilization, and congruency. The circumferential collagen fibers in the meniscus body continue into the anterior and posterior root insertional […]
Historically, a lateral retinacular release was a popular mode of treatment for a variety of knee conditions, including lateral patellar instability, anterior knee pain, and patellar chondromalacia. This procedure was often preferred because of the reported low complication rates. In 1988, Hughston and Deese described medial patellar instability as […]
Bone marrow obtained by iliac crest aspiration is a common source for harvesting mesenchymal stem cells, other progenitor cells, and associated cytokine/ growth factors. Because the use of bone marrow aspirate concentrate (BMAC) is currently approved by the United States Food and Drug Administration, it represents one of the […]
