The articular cartilage, which lines the joints of the limb skeleton, is distinct from the adjoining transient cartilage, and yet, it differentiates as a unique population within a contiguous cartilage element. Current literature suggests that articular cartilage and transient cartilage originate from different cell populations. Using a combination of lineage tracing and pulse-chase of actively...

INTRODUCTION Intra-articular glenoid fractures are extremely rare and may be associated with other injuries. Traditionally open reduction and internal fixation has been recommended in displaced intra-articular glenoid fractures. However open reduction is difficult and it may not be possible to address the associated intra-articular soft tissue injuries. A few reports of arthroscopic assisted fi...

The TMJ, a structurally and functionally complex unit, is enclosed in an articular capsule, which extends from the articular eminence and mandibular fossa superiorly to the neck of the mandibular condyle inferiorly. The condyle is covered and protected by the TMJ disc as the disc slides between the mandibular fossa and articular eminence with joint movement. The presence of the TMJ disc reduces...

Degenerative joint disease is a major cause of functional disability and pain affecting globally hundreds of millions people. In the western countries, osteoarthritis is a major joint disease most often affecting people over 65 years of age. Aging, joint loading, articular cartilage injuries, obesity, and genetic factors are known to influence the development of osteoarthritis. In osteoarthriti...

Introducción: la luxación de articulación temporomandibular es un desplazamiento del cóndilo fuera sus posiciones funcionales dentro fosa articular y eminencia articular, cual ocasiona una pérdida completa función articular. La crónica toda aguda que progresa sin tratamiento específico puede ser carácter recurrente. eminectomía quirúrgico definitivo contra temporomandibular. Objetivo: reportar ...

BACKGROUND Patella alta describes an abnormally high-riding patella in relationship to the femur and has been shown to correlate with patellofemoral pain, instability, chondromalacia, and arthrosis. Conventional measurements of patella alta involve multiple measurements and are often not defined on cross-sectional imaging as related to radiographs. HYPOTHESIS Patellar articular overlap on sag...

Unlike the mandibular condyle, the temporal component of the temporomandibular joint (TMJ) has been the object of relatively few investigations concerning its growth and remodeling. This report provides qualitative and quantitative documentation of microanatomical changes in the mandibular fossa and articular eminence during growth of the rhesus monkey (Macaca mulatta). The thickness of the fib...

Objective(s): Three-dimensional biomimetic scaffolds have widespread applications in biomedical tissue engineering due to similarity of their nanofibrous architecture to native extracellular matrix. Co-culture system has stimulatory effect on chondrogenesis of adult mesenchymal stem cells. This work presents a co-culture strategy using human articular chondrons and adipose-derived stem cells (A...
