ClinConnect Summary

This clinical trial is studying a new approach to ankle replacement surgery for patients with ankle osteoarthritis, a condition that causes pain and stiffness in the ankle joint. The researchers want to compare the outcomes of surgeries performed by both experienced and beginner surgeons using a special tool called Patient Specific Instrumentation (PSI). This tool is designed to help surgeons perform the complex procedure more accurately and quickly, which could potentially make it easier for new surgeons to learn the technique and help more patients in the future.

To be eligible for this trial, participants should be between the ages of 65 and 87, have had an ankle replacement surgery using specific prosthetic devices in 2022, and have at least three months of follow-up data. They must also be able to understand the study and agree to participate. Those who might not qualify include patients who had complications during surgery or other significant health issues that could affect their recovery. Participants will be monitored for surgery outcomes, including how long the surgery takes, any complications, and their recovery experience. Overall, this trial aims to improve the way ankle replacements are performed and make the surgery safer for new surgeons and patients alike.

Eligibility criteria

• Inclusion Criteria:
• • Patient can understand the study's meaning and is willing to sign the study-specific Informed Patient Consent Form.
• • Patient received the implantation of Infinity or Inbone prosthesis using PROPHECY PSI for primary TAR in 2022.
• • There are at least 3 months of follow-up data for this patient.
• • Patient can lay still during the length of duration of the CT-scan.
• Exclusion Criteria:
• • If per-operative the use of the PSI guides was abandoned.
