Total Ankle Replacement Surgery: Expected Duration and Factors

Total ankle arthroplasty (TAA) typically takes 90–120 minutes of operative time. Factors influencing duration:

  • Deformity Severity: Correction of varus/valgus, rotational malalignment adds time.
  • Bone Quality: Osteoporosis, cysts, prior trauma/fusion require grafting or specialized implants.
  • Surgical Approach: Anterior (standard) vs. anterolateral; navigation/robotics may add setup time.
  • Concomitant Procedures: Achilles lengthening, hindfoot fusion, syndesmotic stabilization.
  • Surgeon Experience: High-volume surgeons often faster with fewer complications.

Preoperative anesthesia time (~30–45 min) and postoperative recovery room stay (~1–2 hrs) are additional. Discuss specifics with your surgeon during consent.
