Spacer-type tibial osteotomy versus open wedge high tibial osteotomy and unicompartmental knee arthroplasty for Kellgren-Lawrence grade 3-4 medial unicompartmental knee osteoarthritis in patients younger than 65 years.

ABSTRACT:

Background

Spacer-type tibial osteotomy have been proven a novel and effective osteotomy to treat osteoarthritis, while lack of comparison with other surgical methods in younger patients. This study aims to evaluate the short-term clinical outcomes of spacer-type tibial osteotomy versus open wedge high tibial osteotomy (OWHTO) and unicompartmental knee arthroplasty (UKA) for Kellgren-Lawrence (K-L) grade 3-4 osteoarthritis (OA) in patients younger than 65 years.

Methods

This retrospective study analyzed a total of 224 patients with K-L grade 3-4 knee OA treated from March 2018 to November 2020. Three groups were created according to the operation type. The clinical outcomes recorded preoperatively and at 6, 12 and 24 months postoperatively were the range of motion (ROM), vis
