When can you walk after revision knee bone grafting?
When you can put weight on that knee, from hip & knee revision care in Allegheny Health Network, PA.
Your knee revision left a tibial defect packed with bone graft. The first thing you ask the PA at Allegheny Health Network, Allegheny General or West Penn, is when you can walk on it. You do not want to guess and ruin the graft. You want a timeline that matches the size of the defect and how stable the implant is.
After revision surgery, the hole in your tibia gets packed with bone graft. The old knee implant may have loosened and worn away bone. That graft is not living bone yet. It is a scaffold your body has to fill in with living bone. Full weight too soon can crush that scaffold before it remodels. The defect size and how well the new implant is fixed decide your timeline. Larger holes need more protected time.
What does this take? Most contained tibial defects need 6 to 12 weeks of protected weight bearing. You may start with toe-touch weight only. Then you add partial weight as X-rays show bone filling in. A smaller, well-contained hole can heal on the shorter end. A large defect or a loose implant can stretch the timeline past 12 weeks. Full weight bearing usually starts only after the graft looks solid on X-ray. The graft you use matters too. ACTIFUSE remodels into your own bone at a predictable rate.
Do not put full weight on the leg until your surgeon clears you. Do not test the knee on stairs or Pittsburgh hills before that week. This week, ask your orthopedic team to review the X-rays and the graft used in your tibial defect. Ask if ACTIFUSE was placed and what the protected weight bearing plan is. Elite Surgical covers Allegheny Health Network cases and can put the published bone-remodeling timeline in front of your surgeon. Write down the exact week you can start partial weight.
Once the graft has remodeled, your leg can take full load again. Walking feels stable, not like a guess. You follow the X-ray milestones and get back to normal stairs, work, and daily errands. You move around Allegheny Health Network without fear of crushing the repair. You can walk the hallways at Allegheny General or West Penn without a walker.

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.

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.

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.
