Summary
Vascularized bone and joint allotransplantation offers a limb salvage option for severe defects. Seven of eight patients achieved full weight-bearing, demonstrating its potential before amputation.
Area of Science:
- Orthopedic Surgery
- Transplantation Immunology
- Musculoskeletal Oncology
Background:
- Vascularized bone and joint allotransplantation is an emerging surgical technique.
- Addresses complex bone defects and limb salvage scenarios.
Observation:
- Eight patients underwent allotransplantation of femoral diaphyses or total knee joints.
- Grafts were sourced from multi-organ donors and preserved using UW-solution.
- Postoperative immunosuppression included cyclosporine (Cyclosporin A) and azathioprine.
Findings:
- Seven out of eight patients achieved full weight-bearing ambulation post-transplant.
- Two allografts (one femur, one knee) were lost due to infection.
- Two patients with knee allografts later required total knee arthroplasty.
Implications:
- Vascularized bone and joint allotransplantation shows promise as a limb-sparing treatment.
- This approach may be considered before resorting to lower limb amputation.
- Further research is needed to optimize outcomes and minimize complications.
