osteoarticular allograft
Cadaveric bone graft that includes both bone and articular cartilage for joint reconstruction after tumor resection.
Full Definition
An osteoarticular allograft is a specially prepared cadaveric bone transplant that includes both osseous tissue and viable articular cartilage, used for reconstruction of joint surfaces after oncological resection. These grafts are particularly valuable when tumor resection involves articular surfaces, as they can potentially restore both structural integrity and joint function. The cartilage component may remain viable for several years, providing a biologic joint surface. However, these grafts carry risks including immune rejection, infection, and long-term degeneration, requiring careful patient selection and long-term monitoring.
