Objective:
Defect reconstruction by transposition of well-vascularized muscle (muscle flap) or muscle/skin tissue (myocutaneous flap). Reconstruction of missing muscle unit by free functional muscle transplantation.
Indications:
Treatment of first choice for defect coverage at the distal thigh, knee (including exposed and infected total knee prosthesis), and proximal lower leg.
Contraindications:
Lesions of the popliteal artery. Concomitant lesion of the soleus muscle (impaired plantar flexion).
Surgical Technique:
Proximally pedicled flap: the distal tendinous insertion of the medial and/or lateral gastrocnemius muscle at the Achilles tendon is cut. Vascularization is assured by the medial and lateral sural artery, respectively. - Muscle flaps (medial gastrocnemius, lateral gastrocnemius). - Muscle-skin (myocutaneous) flaps. Distally pedicled flap: the proximal tendinous origin of the medial or lateral gastrocnemius muscle is cut. Vascularization is assured by vascular anastomoses between the two muscles crossing the midline. Because of its unpredictable vascularization, especially after trauma, this technique is rarely used today. To improve arterial inflow, the cut sural artery can be anastomosed in microsurgical technique with an adequate arterial blood vessel at the recipient site.
Postoperative Management:
Complete immobilization for 5-7 days (knee and ankle joints). Progressive increase of range of motion after 1 week (30 degrees /45 degrees /60 degrees /90 degrees ). Postoperative standardized compression therapy, combined with scar therapy (silicone sheet).
Results:
Reliable, excellent functional and aesthetic results.

01:28Muscles of the Leg that Move the Foot and Toes
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
01:23Muscles that Move the Leg
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
01:20Muscles that Move the Thigh
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar fascia...

01:15Veins of Lower Limbs
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the knee,...
