Metaphyseal Sleeves for Revision Total Knee Arthroplasty: Good Short-Term Outcomes.

Abstract

Metaphyseal sleeve prostheses have shown promising results in the management of bone defects at revision TKA. We present a study of their use in aseptic revision TKA. Thirty-five revisions were included in 34 patients with wear or aseptic loosening indicated in 71% of cases. The majority of cases (63%) were AORI grade 2 or greater on the tibia or femur. Knee Society scores were excellent or good in 83% of patients with the same percentage having no or only mild pain. One patient suffered a sleeve-related complication with femoral condylar fractures three years postoperatively; these united with good outcomes. All radiographs were satisfactory; no patient required a further revision. We report good outcomes with the use of metaphyseal sleeves in revision TKA.
