Sumario: | Aim: The aim of our study was to assess the therapeutic effects of platelet-rich plasma (PRP) and bone marrow aspirate concentrate (BMAC) in an animal knee lesion complex associating a large osteochondral defect and meniscal defect resulted from partial meniscectomy, a clinical situation that occurs quite often in orthopedic practice. Materials and Methods: Twenty-one male rabbits were included in the study, and all underwent initial surgery on the right knee to create the osteochondral defect on the internal femoral condyle, and remove the anterior horn of the internal meniscus, simulating a clinical situation. Rabbits were separated in three study groups: control, PRP group, in which three PRP injections were administered, and BMAC group, in which one single BMAC injection was administered. At the end of the six months follow-up period, knees were harvested and further analyzed using confocal microscopy and three-dimensional (3D) reconstruction of the articular surface. Results: Therapeutic groups had better results concerning articular surface remodeling and joint degeneration indicators in comparison to trauma group. Conclusions: Our results suggest that using post-operative regenerative therapies does improve final results concerning surface contact remodeling that was investigated using confocal microscopy and should be considered a valid treatment adjuvant in managing patients with this type of lesion complex, as it improves global joint outcome. |
