摘要

The plastic reconstruction of knee defects poses significant challenges to surgery. The goal is functional coverage with an esthetically pleasing result. Due to thin soft tissue layers over the knee, even superficial injuries can lead to serious complications, such as exposed joints or prostheses. In such cases, flap surgery is often the only way to preserve the limb. Preoperative diagnostics include assessing vascular status through clinical examination and imaging, particularly computed tomography (CT) angiography. In cases of bony defects after infection clearance, the insertion of a spacer is necessary, stabilized by flap surgery. The gastrocnemius flap is suitable for covering extensor surface defects. This muscle provides sufficient coverage area and stability. Medial and lateral flaps are used according to defect location. For extensive defects, a free flap surgery is required. Precise surgical technique is essential to avoid vascular and nerve damage. Postoperative care includes immobilization and careful follow-up. Early mobilization promotes joint function but must ensure transplant stability. Plastic coverage requires experience and interdisciplinary planning. The plastic reconstruction of knee joint defects often enables limb preservation. A clean wound bed and careful vascular management are crucial for success.
