Revascularizing and Decompressive Effect of Subchondral Spongiosotomy with Muscle Implantation in Deforming Gonarthrosis (Experimental Study)

Spongiosotomy with implantation of the marginal portion of the m. tibialis anterior into the zone of trepanation foramen was suggested for the treatment of deforming arthrosis with hypertensive endosteal syndrome. To study revascularising and decompressive effect of the surgery experimental study in 28 dogs was performed. There three groups of animals, 8 dogs in each group: two first groups were control, third group - test one. Deforming gonarthrosis was reproduced in all animals. Animals from group II were subjected to subchondral spongiosotomy, dogs from group III - spongiosotomy with muscle implantation. The study of the intraosseous pressure dynamica and morphologic examination of microsamples confirmed the efficacy of the suggested method and allowed to recommend its use in clinical practice.
