About this study

Tight ankle muscles can produce ankle equinus (limited ability to pull the foot upward) and occur often in children, significantly impacting their ability to walk. If not treated, children with ankle equinus frequently experience reduced function and long-term foot problems, such as pain. Currently, treatment options include surgery or Botulinum toxin (BoNTA) injection into the large calf muscles that point the foot downwards, aiming to reduce their tightness. However, these treatments can be less effective over time, can create prolonged calf weakness, and may require long-term bracing. Another small muscle in the leg, the plantaris, is believed to have some contribution to equinus in many children. It is sometimes included in treatment plans for equinus but its contribution is poorly understood. It is unclear whether targeting the plantaris alone could lead to better treatment of ankle equinus. Understanding the effect of treatments targeting the plantaris could help clinicians improve the management of ankle equinus. In this study, the investigators will look at the impact of surgical treatment to the plantaris in ankle equinus. The investigators hypothesize that the plantaris is a significant contributor to equinus. In this study, data will be collected from children undergoing surgical correction of ankle equinus, including lengthening of the plantaris and lengthening of the larger muscles producing equinus (the gastrocsoleus mechanism). Children will be randomly assig…
