The surgical treatment of full thickness cartilage defects in the knee joint remains a therapeutic challenge. Recently, new techniques for articular cartilage transplantation, such as mosaicplasty, have become available for cartilage repair. The long-term success of these techniques, however, depends not only on the chondrocyte viability, but also on a lateral integration of the implant. We evaluated the feasibility of cartilage welding using albumin solder that was dye-enhanced to allow coagulation with 808 nm laser diode irradiation. Therefore circular cartilage defects (1-2 mm depth and 6 mm diameter) were made and subsequently repaired using healthy cartilage grafts, which were solder welded through the graft. Conventional histology was compared with viability staining to precisely determine the extent of thermal damage after laser welding.
