The aim of this study was to evaluate macroscopically, histologically and immunohistochemically the quality of newly formed tissue in iatrogenic defects of articular cartilage of the femur condyle in miniature pigs treated with the clinically used method of microfractures in comparison with the transplantation of a combination of a composite scaffold with allogeneic mesenchymal stem cells (MSCs) or the composite scaffold alone. The newly formed cartilaginous tissue filling the defects of articular cartilage after transplantation of the scaffold with MSCs (Group A) had in 60 % of cases a macroscopically smooth surface. In all lesions after the transplantation of the scaffold alone (Group B) or after the method of microfractures (Group C), erosions/fissures or osteophytes were found on the surface. The results of histological and immunohistochemical examination using the modified scoring system according to O’Driscoll were as follows: 14.7+/-3.82 points after transplantations of the scaffold with MSCs (Group A); 5.3+/-2.88 points after transplantations of the scaffold alone (Group B); and 5.2+/-0.64 points after treatment with microfractures (Group C). The O’Driscoll score in animals of Group A was significantly higher than in animals of Group B or Group C (p
