Surgical Treatment for Ankle Equinus
(Plantaris Sx Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial investigates whether targeting a specific small muscle in the leg, the plantaris, can improve treatment for children with ankle equinus. Ankle equinus makes it difficult to pull the foot upward, leading to walking problems and long-term foot issues. Participants will undergo surgery to lengthen the plantaris muscle alongside other standard procedures, and researchers will compare the results. The trial seeks children who struggle with conditions like cerebral palsy or toe walking and plan to have surgery to manage ankle tightness. Understanding the plantaris muscle's role could lead to better treatments for children with tight ankles. As an unphased trial, this study offers a unique opportunity to contribute to groundbreaking research that could enhance future treatments for children with similar conditions.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this surgical treatment is safe for children with ankle equinus?
Research has shown that focusing on the plantaris muscle-tendon during surgeries for ankle equinus is generally safe. Previous studies on similar treatments have demonstrated positive results. For instance, one study found that removing the plantaris tendon during surgery led to good outcomes, with patients experiencing fewer complications and requiring fewer follow-up surgeries.
Another method studied is percutaneous needle tenotomy, a minimally invasive procedure that cuts tight tendons. This method has proven safe, even for patients with other health issues. This suggests that procedures targeting tendons, like the plantaris, are well-tolerated.
Overall, existing evidence supports the safety of focusing on the plantaris muscle-tendon in treating ankle equinus. This is promising for those considering participation in clinical trials for this condition.12345Why are researchers excited about this trial?
Researchers are excited about these surgical treatments for ankle equinus because they explore new approaches to addressing muscle tightness and limited range of motion. Unlike traditional methods that often involve physical therapy, casting, or standalone surgical techniques, these treatments combine Plantaris tenotomy with either Tendoachilles (TA) lengthening or gastrocnemius (GN) recession. This dual approach aims to improve flexibility and mobility more effectively by targeting multiple components of the calf muscle complex. Additionally, by varying the order of these procedures, researchers hope to discover the most effective sequence for maximizing patient outcomes.
What evidence suggests that targeting the plantaris muscle could be effective for treating ankle equinus?
Research has shown that focusing on the plantaris muscle can greatly improve ankle movement in people with ankle equinus. In this trial, participants will undergo different surgical sequences involving the plantaris muscle. One group will receive Plantaris tenotomy surgery before Tendoachilles (TA) lengthening or gastrocnemius (GN) recession, while another group will undergo Tendoachilles (TA) lengthening or gastrocnemius (GN) recession before Plantaris tenotomy. Previous studies have demonstrated that simply cutting the plantaris tendon improved ankle movement by over 50%. Another study identified the plantaris muscle as a key factor in causing this condition. This suggests that treating the plantaris muscle might effectively help children with ankle equinus. Treatments targeting this muscle could lead to better walking and less pain.26789

Are You a Good Fit for This Trial?
This trial is for children with conditions like Cerebral Palsy or Spinal Cord Injury that cause tight ankle muscles, limiting their ability to pull the foot upward. They must be undergoing surgery for ankle equinus and can't have other treatments planned.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Surgical Intervention
Participants undergo surgical intervention for ankle equinus, including plantaris tenotomy and either Tendoachilles lengthening or gastrocnemius recession
Intra-operative Assessment
Maximum passive ankle dorsiflexion is measured at several intervals during surgery
Follow-up
Participants are monitored for safety and effectiveness after surgical intervention
What Are the Treatments Tested in This Trial?
Interventions
- Plantaris Muscle-tendon Targeting
Trial Overview
The study tests if changing the order of lengthening the plantaris muscle affects treatment outcomes in ankle equinus. Children are randomly assigned to have plantaris lengthened before or after gastrocsoleus lengthening, all in one surgery session.
How Is the Trial Designed?
