Is synthetic bone graft safe in infected revision?
Straight talk on synthetic graft safety for hip & knee revision, Allegheny Health Network, PA.
You're revising an infected total knee. There is bone loss behind the tibial component. You need something to fill that defect, but you cannot put in a material that hides bacteria. In Allegheny Health Network, surgeons ask the same question: is a synthetic bone graft safe in a contaminated field?
When you revise an infected total knee, you often find a hole in the bone behind the tibial component. That hole worries you. Bacteria can hide in dead bone or in a dense block of donor bone. A structural allograft can act like a dead piece, called a sequestrum. Antibiotics cannot reach inside it. The infection comes back.
The size of the bone defect drives the scope. Small contained holes may need one or two ACTIFUSE syringes. Bigger defects behind a loose tibial tray take more volume and more time in the operating room. Cost depends on your hospital contract and the defect size. You avoid a second surgical site from harvesting the patient's own bone. Ask your rep for a case-by-case quote.
Inside Allegheny Health Network, call Elite Surgical this week. Ask for the clinical data on ACTIFUSE in infected revision. Confirm the graft is a porous silicate-substituted calcium phosphate, not a solid block. Use it only as part of a staged protocol with local antibiotics. Do not place a structural allograft in a contaminated field if a porous synthetic graft will fill the defect.
After surgery, the porous scaffold lets blood vessels grow in. Antibiotics reach the space. The graft then remodels into the patient's own bone over the next months. The revision knee seats on stable bone. You see a clean, quiet joint at follow-up.
Other things people in Allegheny Health Network ask
bone graft for tibial bone loss revision knee
Pack the contained defect with a porous synthetic bone graft scaffold. It should hold shape and remodel as the revision heals. Do not leave the defect empty or filled with cement alone.
bone graft substitute for large acetabular defect revision hip
Pick a graft that packs the defect well and has high porosity for bone ingrowth. ACTIFUSE's 80% porous scaffold fills contained defects and remodels into the patient's own bone as the revision heals. For very large defects, consider a moldable version like ACTIFUSE SHAPE to adapt to irregular contours. Avoid grafts that resorb too fast and leave the cup unsupported.
bone graft for tibial defect during knee revision
Pack the contained defect with a moldable bone graft substitute that has high porosity and remodels into host bone. Avoid autograft if the patient already has a second surgical site. The graft should support the new implant while healing.
how to choose bone graft femoral defect revision hip
Look for a porous scaffold that holds shape when packed and remodels over time. Match the graft format to the defect. A runny material will not stay in an open femoral defect.
how to choose bone graft substitute for femoral defect revision hip
Choose a moldable synthetic bone graft substitute for irregular femoral defects. It should pack into the canal without extra instruments. Look for a graft that remodels into host bone so the area is not left with permanent filler.
