Here is an example of one of the early Chondrofix implants, doing well at nine months, that was rehabbed with early weight bearing.
I have six of these implanted, just over a year for the earliest ones. I am still finding my way on the utility of a sterilized allograft implant that has no living cells. There is one “second look’ (see prior post) and several MRs of this quality (3T), demonstrating good integration of the bony plug and retention of the cartilage cap. This surface is immediately put under load and so far has been holding up very well, but it is still early. IMO this MRI is very favorable at this (still) early timepoint.
Note the nice cartilage layer that spans the surface of the Chondrofix implant.
The long shelf life of this implant (24months) allows the surgeon to have it available just “in case” and unlike Denovo NT does not require a commitment to use it. This can be a significant advantage in certain situations, notably those of a partial joint replacement when the surgeon discovers a satellite lesion not covered by the implant.
The convenience of early weight bearing may be attractive to certain patients. However, the advantage of a biologically active implant like Denovo NT is that is improves and grows over time, which is a feature not to be anticipated with a large scaffold like Chondrofix,
