The "Lollypop" technique for polyethylene exchange in total ankle replacement
1Musgrave Park Hospital, Stockmans Lane, Belfast, United Kingdom.
Summary
This study presents a straightforward method for removing the polyethylene meniscus bearing during revision total ankle replacement surgery. This technique aids in the exchange of worn components for improved patient outcomes.
Area of Science:
- Orthopedic surgery
- Biomaterials science
- Medical device engineering
Background:
- Total ankle replacement (TAR) is a common procedure for end-stage ankle arthritis.
- Polyethylene bearing surfaces in TAR can wear over time, necessitating revision surgery.
- Revision TAR presents unique challenges, including the removal of existing components.
Purpose of the Study:
- To describe a simple and effective technique for removing the polyethylene meniscus bearing surface during revision total ankle replacement.
- To facilitate the exchange of worn bearing surfaces in previously implanted total ankle prostheses.
Main Methods:
- The study details a specific surgical technique for the removal of the polyethylene meniscus bearing.
- This method is applicable to patients requiring re-operation for component exchange after initial total ankle arthroplasty.
Main Results:
- The described technique allows for straightforward removal of the polyethylene meniscus bearing.
- This facilitates the planned exchange of the bearing surface during revision surgery.
Conclusions:
- A simple technique for polyethylene meniscus bearing removal in revision total ankle replacement is presented.
- This method simplifies a critical step in revision total ankle arthroplasty, potentially improving surgical efficiency.
