Summary
A distally based sartorius flap combined with a skin graft successfully reconstructed a large anterior knee defect after trauma. This technique provided excellent coverage and facilitated full patient recovery, demonstrating its efficacy in complex soft-tissue reconstruction.
Area of Science:
- Orthopedic Surgery
- Reconstructive Surgery
- Trauma Surgery
Background:
- Coverage of soft-tissue defects around the knee requires diverse reconstructive strategies.
- Large anterior knee defects pose significant reconstructive challenges.
- Primary closure is often not feasible for extensive knee joint soft-tissue injuries.
Observation:
- A 30-year-old male presented with a large anterior knee defect post-motorcycle accident, exposing the patella and patellar tendon.
- A distally based sartorius muscle flap was employed for wound coverage.
- The sartorius muscle flap was transposed via a subcutaneous tunnel and augmented with a full-thickness skin graft.
Findings:
- The distally based sartorius flap provided successful and viable coverage for the large anterior knee defect.
- The full-thickness skin graft integrated well with the underlying muscle flap.
- The patient achieved full recovery and returned to work within one month post-operation.
Implications:
- The distally based sartorius flap is a viable reconstructive option for large anterior knee soft-tissue defects.
- This surgical approach offers a successful alternative when primary closure is not feasible.
- Effective soft-tissue reconstruction promotes rapid patient recovery and return to function.
