Abstract:
The majority of patients with Achilles tendinopathy respond to nonoperative treatment. In patients with refractory symptoms, surgery can be considered. If paratenonitis is present, the paratenon is partially excised, and adhesions are released. Areas of symptomatic tendinosis are excised with repair of the residual defect in the Achilles tendon. An alternative for patients with tendinosis who are at increased risk for wound problems or who do not want a large open incision is percutaneous or endoscopic tenotomy. A symptomatic Haglund's deformity or inflamed retrocalcaneal bursa is excised. Augmentation of the Achilles tendon may be considered if debridement threatens the structural integrity of the tendon, in older patients, and in revision surgery.

Muscles 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.

Muscles 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...
