Early Scandinavian Total Ankle Replacement (STAR) shows promising results, with most patients experiencing pain-free daily activities. Surgeons should have specialized training due to a steep learning curve.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Early total ankle replacement (TAR) designs exhibited high failure rates.
  • Recent advancements in 3-piece, meniscal bearing total ankle replacement have shown improved outcomes.

Purpose of the Study:

  • To review the early clinical results of the Scandinavian Total Ankle Replacement (STAR) in Northern Ireland.
  • To assess patient satisfaction and identify complications associated with the initial use of STAR prostheses.

Main Methods:

  • Retrospective review of the first 22 Scandinavian Total Ankle Replacement (STAR) prostheses implanted in 20 patients.
  • Mean follow-up period of 26 months.
  • Analysis of patient-reported pain during daily activities and documented complications.

Main Results:

  • Seventeen out of 20 patients reported being pain-free during normal daily activities.
  • Two cases required revision surgery due to technical errors.
  • Complications included malleolar fractures, poor wound healing, and postoperative stiffness.

Conclusions:

  • The Scandinavian Total Ankle Replacement (STAR) demonstrates high patient satisfaction in early outcomes.
  • A significant learning curve exists, suggesting restricted use to specialized foot and ankle surgeons.
  • Continued use of total ankle arthroplasty is encouraged based on these promising initial results.
