Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

The STAR™ Ankle prosthesis shows excellent long-term survivorship, with 91% of implants remaining after nearly a decade. This total ankle replacement significantly improves pain and function for patients with ankle arthritis.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Medical Device Technology

Background:

  • Growing interest in total ankle replacement (TAR) due to advancements in prostheses.
  • Limited long-term survivorship data for existing TAR options.
  • The STAR™ Ankle prosthesis is a novel three-part design approved in the U.S.

Purpose of the Study:

  • To evaluate the long-term survivorship and clinical outcomes of the STAR™ Ankle prosthesis.
  • To assess the functional improvement and patient satisfaction following TAR.
  • To identify complications associated with the STAR™ Ankle prosthesis.

Main Methods:

  • Prospective study of 84 STAR™ Ankle replacements in 80 patients.
  • Postoperative evaluation using the AOFAS ankle-hindfoot score for pain and function.

  • Serial radiographic assessment of prosthesis stability, alignment, and complications.

    • Main Results:

    • 91% implant survival at an average 9.1-year follow-up; 90% at 10 years.
    • Significant improvement in AOFAS scores (average 39-point increase), pain, and function.
    • High patient satisfaction (92%), with 21 complications including 14 additional procedures.

    Conclusions:

    • The STAR™ Ankle prosthesis demonstrates excellent long-term survivorship.
    • It is a viable and effective option for treating ankle arthritis.
    • This study provides crucial U.S. prospective data on TAR outcomes.
