Peroneus Longus Graft :Effect in Foot and Ankle Function

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to report the ankle and foot functions via American orthopedic foot and ankle society score (AOFAS), peronei muscle testing ,handheld dynamometer and radiological outcomes after harvesting autogenous peroneus longus tendons for ligaments reconstruction.

Detailed Description
-----------------
Using a Peroneus longus tendon (PLT) as an autograft is a common procedure and has been used previously for deltoid ligament reconstruction in flatfoot deformity correction . Recently, (PLT) is gaining popularity as a graft option in primary anterior cruciate ligament (ACL) reconstruction surgeries with biomechanical studies showing tensile strength and clinical outcomes comparable to quadrupled hamstring grafts. In addition to using PLT for isolated (ACL), it is also used in posterior cruciate ligament (PCL) reconstruction, medial collateral ligament reconstruction, posterolateral corner reconstruction of the knee, or knee multiple ligament injuries . The partial-thickness of the tendon has been used variably in knee ligament surgery.. Being a powerful muscle in plantar flexion and eversion of the foot, there might be associated ankle functional impairment. To the authors knowledge, there is a gap in science evaluating donor site morbidity. The aim of this study is to report the clinical and functional outcome of the donor site for better explanation of the cons and pros of using PLT as a graft in joint ligamentous injury .

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: treatment arm<br>peroneus longus autograft | Procedure: peroneus longus autograft<br>* Peroneus longus tendon graft will be harvested with a longitudinal skin incision at 2 to 3 cm (2 finger-breadths) above and 1 cm (1 finger-breadth) behind the lateral malleolus, followed by superficial fascia incision in line with skin incision followed by incision of the tendon sheath proximal to the retinaculum. The peroneus longus and peroneus brevis tendons will be then identified. The tendon division location marked at 2 to 3 cm above the level of the lateral malleolus.The peroneus longus tendon will be exposed on its posterolateral surface through the incision after carefully incising the fascia<br>|
