Wound healing after the implantation of the cartilage autograft and allograft (an experimental study)

Abstract

Objective. To compare the wound healing after implantation of the freshly frozen allogeneic cartilage and the autogenic cartilage in a cutaneous flap.Materials and methods. Two groups of eighteen non-breed white lab rats weighing 180-200 g of both genders were studied. Each specimen had a plastic material with the inclusion of a skin flap and cartilage graft formed. Group 1 used the animal’s own cartilage, group 2 used freshly frozen allogenic cartilage. Histological examination of the flap and graft preparations was carried out on the 7th, 14th and 21st days after the intervention.Results. Semi-quantitative evaluation of inflammation and tissue reaction after cartilage autograft and allograft implantation was carried out. A gradual decrease in the evidence of the inflammatory reaction and the formation of a fibrous capsule around the implant during the study period was registered. The comparative analysis revealed no statistically significant differences in each of the indicators.Conclusion. Implantation of an allograft from freshly frozen cartilage has no negative effect on skin flap wound healing in the experiment. Freshly frozen allogenic cartilage can be used for reconstructive interventions on a par with autologous material.
