Assessment of Balance and Function After Lateral Ankle Ligament Repair

Study Overview
=================
Brief Summary
-----------------
Approximately 85% of ankle injuries are lateral region injuries.Surgical repair of lateral ligaments is indicated if there is more than 20 degrees of varus or more than 15 mm translation, if conservative treatment is ineffective and degree of damage is high and chronic instability has developed.After the surgery in addition to pain and edema control, weight transfer is not performed on the ankle for 6 weeks.Therefore, this process may adversely affect the muscle strength and range of motion of the ankle, and lower extremity performance and muscular synergies of balance.Although pathological changes caused by ligament damage have been investigated very well in the literature, it is not clear how surgical repair affects these changes. In our study we aim to investigate post-surgical changes. Primary aim of the study is to evaluate the balance parameters of individuals who have undergone anterior talofibular ligament and / or calcaneofibular ligament repair, and its secondary purpose is to evaluate lower extremity performance, ankle functionality, pain, range of motion and muscle strength and compare them with healthy individuals. Our hypothesis is that the balance, lower extremity performance and functionality, pain, range of motion and muscle strength of patients who have undergone ankle lateral ligament repair are worse than healthy individuals.
