The aim of this study is to Compare functional outcome and the recovery time of reinsertion of achilles tendon VS zadek osteotomy in insertional achilles tendinopathy.
Insertional Achilles tendinopathy is characterized by chronic posterior heel pain associated with posterosuperior calcaneal exostosis or intratendinous ossification. The etiologies include retrocalcaneal exostosis, the diseased tendon, enthesopathy, and Haglund's deformity. The nonsurgical therapies, such as physical therapy, stretching and strengthening of the gastrocnemius-soleus muscle complexes, nonsteroid anti-inflammatory drugs, and footwear modifications, are chosen as the initial treatment. Local injection of the steroid is not recommended because it might lead to increase risk of tendon rupture.
Surgical intervention is a suitable option when conservative treatment for more than 6 months has failed. Open detachment with reattachment of the Achilles tendon is a common surgery combined with calcaneoplasty and debridement of the retrocalcaneal bursitis and pathologic Achilles tendon. Suture techniques using bone anchors have been described to reattach the Achilles tendon with excellent results. percutaneous Osteotomy is another option, first described by Zadek in 1939 which was later modified in 1965. zadek osteotomy is a dorsal closing wedge calcaneal osteotomy that allows the tuberosity of Haglund deformity to be brought forward. This operation can change the calcaneus' anatomical length and elevate the distal insertion point of the AT. The rationale of a ZO was to reduce the impingement between the anterior aspect of the Achilles tendon and the superior angle of the posterior calcaneal tuberosity. By shortening the calcaneus and altering the orientation of the Achilles tendon fibers it is believed to decrease stress across the tendon at its insertion.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Reinsertion achilles tendon | Active Comparator | Reinsertion Achilles tendon by 2-4 anchors. |

| Reinsertion achilles tendon | Procedure | Prone position, tourniquet over the thigh, direct midline incision, 2.0 cm proximal the insertion of the Achilles tendon up to 4.0 cm prolonged distal to the insertion is recommended. This is followed by a totally disinsertion of TA. At least a debridement of inflammatory or necrotic tissue as well as the removal of bony tissue is performed. tendon is re-inserted by 2-4 anchors. |
| Measure | Description | Time Frame |
|---|---|---|
| the time needed to return to normal daily activities (functional outcome) assessed by foot and ankle outcome score. | foot and ankle outcome score is a tool to measure the symptoms, stiffness, pain, function, daily living, sports and recreational activities of foot and ankle problems. It is based on 100 questions and ranges from 0 to 100, with higher scores indicating more severe symptoms or limitations. | up to1 year post baseline |
| Measure | Description | Time Frame |
|---|---|---|
| Pain assessed by the visual analogue scale. | The visual analogue scale (VAS) is a scale used to determine the pain intensity experienced by individuals. It consists of a line, approximately 10-15 cm in length, with the left side signifying no pain with a smiling face image and the right side signifying the worst pain ever with a frowning face image. The VAS is used to assist individuals to determine pain levels, who may not be accustomed to rating their pain on other types of scales, such as a numeric rating scale. |

| Zadek osteotomy | Procedure | lateral position, under spinal anesthesia, tourniquet over the thigh, oblique lateral heel incision starting just anterior to the Achilles tendon, at a 45 angle to the long axis of the calcaneus posterior to the course of the sural nerve. A calcaneal osteotomy was then performed, two Kirschner wires, were then inserted from the posterior aspect of the calcaneus, over which cannulated screws were used for fixation of the osteotomy. |
