Patologiczne zerwanie więzadła krzyżowego przedniego u psów

The authors present a hypothesis about the relationship of the mode of life without sufficient movement activity and the regressive lesions of the ligaments and fascias. They suggest to call the state of the rupture of such ligaments more precisely: pathologic rupture of the cranial cruciate ligament (CCL). Histologic examinations of the pathologically ruptured CCL and the fascia lata, collected from four dogs with the above diagnosis, revealed hyaline degeneration, an imperceptible morphologic structure and focal necrosis, acidophileness and homogenization. In addition, there was found the presence of cellular infiltration composed of neutrophils, histiocytes, fibroblats and lymphoid cells. The age of the dogs ranged from 3 to 10 years and the lameness appeared without joint overextension or overloading. In dogs with pathologic rupture of the CCL an extracapsular stabilization of the joint or synthetic prosthesis of the ligament should be made.
