摘要
Background: Extensive and complex contractures in the anterior knee area can pose a significant challenge for reconstruction due to insufficient skin and soft tissue coverage and poor cosmetic and functional outcomes using traditional methods. We presented our experience with pre-expanded muscle-sparing latissimus dorsi (LD) free flap as an alternative option for large-scale anterior knee reconstruction. Methods: From January 2016 to December 2020, we applied this surgical technique in six patients with large postburn or post-traumatic contractures of the anterior knee. After tissue expansion of several months, the expanded muscle-sparing LD free flap was harvested and transferred to resurface the lesions. Operative procedures, postoperative complications, and long-term outcomes were evaluated. Results: A total of six patients aged 7 to 32 years (mean: 20 years) were reconstructed successfully without any major complication. The flap ranged from 20 x 8 cm to 40 x 16 cm. All donor sites were primarily closed. Follow-up (range: 12 to 24 months) evaluation showed satisfactory results in both cosmetic and functional aspects. Conclusions: Pre-expanded muscle-sparing LD free flap is a reliable and effective choice for extensive anterior knee contracture reconstruction with satisfactory esthetic and functional outcome. It can provide substantial amount of soft tissue coverage with minimal complications and donor-site morbidity. Furthermore, it offers a good basis for next-step orthopedic surgery, such as total knee arthroplasty (TKA). (c) 2022 British Association of Plastic, Reconstructive and Aesthetic Surgeons.
