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...

Total ankle replacement using the Ankle Evolution System showed satisfactory medium-term outcomes and high patient satisfaction. However, concerns regarding osteolysis led to the implant

Area of Science:

  • Orthopaedic Surgery
  • Biomaterials Science

Background:

  • Total ankle replacement (TAR) aims to alleviate pain and restore function in patients with end-stage ankle arthritis.
  • The Ankle Evolution System is a specific implant used for TAR, requiring evaluation of its long-term efficacy and safety.

Purpose of the Study:

  • To evaluate the medium-term clinical outcomes and implant survival of the Ankle Evolution System in total ankle replacement.
  • To assess patient satisfaction and identify complications associated with this specific TAR system.

Main Methods:

  • A prospective study of 38 consecutive patients undergoing total ankle replacement with the Ankle Evolution System.
  • Follow-up included clinical assessments (American Orthopaedic Foot and Ankle Society - AOFAS scores for pain and function) and radiographic evaluation.

  • Implant survival was analyzed using Kaplan-Meier survival analysis.

    • Main Results:

    • The cumulative survival rate at six years was 94.7%.
    • Mean AOFAS scores indicated good pain relief and functional improvement (Total AOFAS: 88.1, Pain: 35.8).
    • Nine patients (23.7%) showed radiological evidence of osteolysis, and ten patients (26.3%) experienced edge-loading, with nine requiring corrective surgery.

    Conclusions:

    • The Ankle Evolution System demonstrates satisfactory medium-term results and high patient satisfaction in total ankle replacement.
    • The occurrence of osteolysis is a significant concern, prompting the manufacturer to withdraw the implant.
    • Long-term benefits and risks of this specific TAR system require further investigation.
