How to Use the TayCo Acute XAB Brace for Bridle Tendon Transfer Recovery by Dr. Nicholas Strasser, MD

An Evidence Based Approach for Success

Following a Bridle tendon transfer, maintaining alignment and support through the midfoot and ankle is critical for proper tendon healing and restoration of balanced gait mechanics. After a period of immobilization in a splint and cast for four weeks, I transition patients to a boot and then to the TayCo® Acute XAB external ankle brace for continued support.

I prefer the Acute XAB Brace because it provides reliable ankle stabilization without the discomfort of a traditional in-shoe brace. Since it attaches externally to the patient’s footwear, it eliminates direct pressure over the surgical site and foot, which patients often find uncomfortable or intolerable with standard ankle-foot orthoses.

The Acute XAB ankle support brace is locked in dorsiflexion, which helps reinforce the transferred tendon’s new line of pull and provides additional dorsiflexion support during early gait retraining. This helps reduce overuse of the healing tendons and encourages proper foot positioning during stance and swing phases.

Patients consistently report that the Acute XAB is comfortable, easy to wear, and provides a noticeable sense of pain relief and functional stability. It enables a smoother progression from immobilization to protected weight-bearing and ultimately back to full activity, with higher compliance and confidence in the recovery process.

By incorporating the Acute XAB brace into my protocol, I aim to protect the surgical reconstruction while promoting a more natural, supported gait — all without compromising patient comfort.

Postoperative Rehabilitation Protocol: Bridle Tendon Transfer

Informed by Johnson et al., Foot Ankle Int. 2015; 36(11):1287–1296

Overview

The Bridle tendon transfer (tibialis posterior + peroneus longus to the dorsum of the foot) is designed to restore active dorsiflexion and correct foot drop. Postoperative care must protect the transfer while gradually restoring mobility and strength. The following protocol is consistent with principles from established foot and ankle rehab programs and peer-reviewed recommendations.

Phase 1: Immobilization & Protection

Weeks 0–4

  • Immobilization: Short leg, non–weight-bearing cast with ankle in neutral
  • Weight-Bearing: Strict non-weight-bearing
  • Activity: Foot elevation, maintain mobility of hip and knee
  • Goals: Protect tendon repair, minimize swelling
  • Transition: Cast changed at 10–14 days post-op after suture removal

Phase 2: Transition to Controlled Mobility

Weeks 4–6

  • Immobilization: Transition to a CAM walker boot
  • Weight-Bearing: Begin touch-down weight-bearing, progress to partial then full weight-bearing as tolerated by end of week 6
  • ROM Guidelines:
    • Week 6: Begin active and active-assisted dorsiflexion
    • Gentle active plantarflexion may begin
    • Avoid passive plantarflexion until at least 12 weeks to protect the tendon repair
  • Therapy Focus: Muscle re-education, proprioception (seated or with brace), gentle isometrics

Johnson et al. emphasize starting active ROM at 6 weeks to retrain the transferred tendon while protecting it from elongation, and delaying passive plantarflexion until 3 months to prevent overstretching.

Phase 3: Functional Strengthening

Weeks 6–12

  • Bracing: Transition out of boot at 6 weeks into:
  • Weight-Bearing: Full weight-bearing in brace
  • ROM Focus:
    • Continue dorsiflexion ROM
    • Gradually introduce passive plantarflexion after 12 weeks
  • Therapy Goals:
    • Progress dorsiflexor strength
    • Normalize gait in brace
    • Initiate closed-chain balance drills
    • Begin stationary bike or elliptical as tolerated

Phase 4: Advanced Rehab & Weaning

Weeks 12–20

  • Brace Use: Continue brace for all activity through 16 weeks, then wean to brace only for outdoor or higher-risk activities
  • Therapy Focus:
    • Full active ROM
    • Calf strengthening (heel raises, resistance walking)
    • Proprioception, single-leg balance
    • Functional training, light jogging or sport-specific drills

Phase 5: Return to Activity

20+ weeks

  • Brace Use: Discontinue for daily use; may continue for sports or uneven terrain
  • Therapy Focus:
    • Full return to desired level of activity
    • High-level balance, agility, and plyometric drills if indicated
    • Functional testing for return to sport/work

Key Points from the Literature

  • All patients in the Johnson et al. study were brace-free for daily activities postoperatively by 3–6 months.
  • Initiation of active ROM at 6 weeks showed good outcomes with protection against overstretching.
  • Using tendon-to-bone fixation (vs tendon-to-tendon) appears to reduce the risk of failure due to elongation over time.
  • No evidence of arch collapse was seen on radiographic follow-up at 2 years.

 

Important: This protocol is a general guideline. All patients should follow the specific instructions provided by their surgeon. Always consult your physician before beginning or progressing with rehabilitation exercises.
