How does the rate of surgical revision for autograft compare to recombinant human bone morphogenetic protein?

The correct choice indicates that the rate of surgical revision is lower for autograft procedures compared to those using recombinant human bone morphogenetic protein (rhBMP). Autografts, which involve using the patient's own tissue, generally promote better biological integration and healing, leading to a decreased likelihood of complications or failure requiring revision surgery.

In contrast, rhBMP, while effective in promoting bone healing, has been associated with complications such as seroma formation, inflammatory responses, or inadequate bone healing in some cases. These factors can contribute to a higher rate of revision surgeries when rhBMP is used, as patients may experience issues that necessitate a follow-up procedure.

Thus, the comparison showcases the advantages of using autografts in terms of lower revision rates, emphasizing the importance of selecting the appropriate graft type based on patient-specific factors and clinical considerations.
