Simultaneous induced membrane technique to reconstruct an obliterated floating knee.

Area of Science:

• Orthopedic surgery
• Regenerative medicine
• Biomaterials science

Background:

• Segmental bone loss presents a significant challenge in orthopedic trauma.
• The induced membrane technique offers a biological solution for bone reconstruction.
• Previous applications have demonstrated its potential in various bone defect scenarios.

Observation:

• A patient presented with severe open lower limb trauma, involving both femur and tibia bone loss.
• Articular surfaces of both the knee and ankle joints were compromised.
• The Masquelet technique was employed to manage the extensive bone defects.

Findings:

• Successful reconstruction of both femoral and tibial bone segments was achieved using the induced membrane technique.
• The approach facilitated bone regeneration and limb salvage in a complex, multi-site injury.
• This case highlights the technique's efficacy in managing combined diaphyseal and articular bone loss.

Implications:

• The Masquelet technique is a viable option for complex, combined diaphyseal and articular bone defects.
• This case expands the understanding of the technique's application in severe lower limb trauma.
• Further research into optimizing the technique for combined injuries is warranted.
