Introduction

The purpose of this study was to investigate whether combining PRP or concentrated bone marrow aspirate (CBMA) with a biphasic collagen/glycosaminoglycan (CG) scaffold would improve the outcome of the treatment of full thickness osteochondral defects in sheep.

Materials and Methods

Osteochondral defects (5.8×6mm) were created in the medial femoral condyle (MFC) and the lateral trochlea sulcus (LTS) of the stifle joints of 24 sheep. Defects were either left empty or filled with a 6×6mm CG scaffold, either on its own or in combination with PRP or CBMA (n=6). At 6 months the sheep were euthanised, and the repair tissue subjected to mechanical testing, gross morphological analysis, semi quantitative histological scoring and immunohistochemical staining including types I, II and VI collagen.
