ABSTRACT

Background:

The injury repair process in tendons and ligaments includes different phases such as inflammation, neovascularization, fibroblast proliferation and fibrosis. Collagen type and tissue characteristics of tendon and ligament repair are described such as type collagen differentiation and properties of the scars tissue. The degeneration of articular cartilage when, characterized by loss of the articular layers associated of the decreased of proteoglycans. The aim of this study is to describe by histochemistry techniques the characteristics of tissue scar, collagen type in the repair process of tendons and ligaments, as well as articular cartilage degeneration.Materials, Methods &

Results:

Tissue samples of equine tendons, ligaments and articular cartilage of the metacarpophalangeal joint region were evaluated by ultrasonography, macroscopically and prepared for routine histopathology (H&E staining). The inclusion criterion of the samples in this study was based on the presence of lesions characterized in H&E stain as fibroplasia, neovascularization, collagenolysis, chondroid metaplasia in tendons and ligaments and fibrillation and cartilaginous eburnation lesions in the articular cartilage samples. The Masson’s trichrome, Picrosirius red and Alcian blue staining techniques were also performed in addition to H&E. Pathologic findings in the tendons and ligaments included fibroplasia, collagenolysis, chondroid metaplasia and lymphohistioplasmacytic inflammation. Tendons and ligaments scars were composed of type III collagen but there was also some type I collagen. Fiber alignment of tendons and ligaments in the reorganization tissue was not flawless and the fiber appearance was characterized by a lack of the fiber crimp and parallelism. The fibroplasia was characterized by endotendinous tickening areas associated with the presence of loose connective tissue.[...]
