Tibial bone loss behind your failed knee replacement
Hip & knee revision in Allegheny Health Network, PA — the answer to a contained tibial defect.
You had a knee replacement, and now it's loose. The tibial bone behind the implant has worn away, leaving a contained defect. In Allegheny Health Network, PA, hip and knee revision surgeons need a bone graft that packs the void and holds its shape while the new knee heals.
When a knee replacement fails, the tibial component can loosen. The bone underneath may resorb, leaving a cavity. This is called a contained tibial defect. It's like a bucket with walls. You can't just fill it with cement alone because cement doesn't turn into living bone. You need a scaffold that supports the new implant and remodels over time.
Bone graft material typically adds a few thousand dollars to the revision case, but it eliminates the need for a second surgery to harvest your own bone. The final cost depends on the size of the defect and the hospital's pricing. Using a synthetic graft avoids a separate incision for autograft, which means less pain and no donor site risk.
Your surgeon will plan the revision. Ask if they will use a synthetic bone graft to fill the tibial defect. Don't accept cement alone if the defect is contained. Elite Surgical can provide ACTIFUSE, a silicate-substituted calcium phosphate scaffold that is 80% porous and remodels into your own bone. You can call us to discuss if your surgeon is familiar with this graft.
Once the revision is done and the graft is packed, the new implant sits on a stable foundation. The scaffold slowly turns into your own bone over months. You go through rehab, and the knee feels solid again. No more loose baseplate. The bone defect is filled and healed.
Other things people in Allegheny Health Network ask
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.
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.
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.
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.
bone graft substitute cost revision hip
Ask for per-cc or pack pricing, not a flat case price. Cost depends on the size of the acetabular or femoral defect. Compare synthetic graft cost to autograft, which includes OR time and a second incision.
