The Use of Metaphyseal Cones and Sleeves in Revision Total Knee Arthroplasty.

Abstract

The burden of revision total knee arthroplasty (rTKA) is expected to increase with the rise in the number of TKA procedures being performed yearly. Management of bone loss during rTKA is challenging and necessitates appropriate surgical planning. Metaphyseal cones and sleeves have emerged as an increasing popular option for addressing metaphyseal femoral and tibial bone loss when performing rTKA. Understanding what cones and sleeves are commercially available and when to use them are critical parts of preoperative evaluation and planning. The purpose of this comprehensive review was to present different design philosophies, types of manufacturing, clinical outcomes, and the versatility and interchangeability of varying cones and sleeves with different TKA revision systems.
