Meniscus extrusion on standing weightbearing ultrasound is associated with limb alignment and posterior tibial slope in healthy knees.

ABSTRACT:

Purpose

The purpose of this study was to report meniscus extrusion in asymptomatic knees using ultrasound sonography (US) and evaluate the association between the extrusion and joint space width, coronal alignment, and posterior tibial slope (PTS).

Methods

Patients ≥18 years with meniscus allograft transplantation with a contralateral knee that was asymptomatic, Kellgren-Lawrence grade ≤1, without a history of pathology were included. Knee pain or acute injury requiring orthopaedic evaluation, prior knee surgery, and inflammatory arthropathies were excluded. Meniscus position was captured via US in supine, bipodal, and unipodal stances. Participants underwent radiographic imaging, and joint space width, alignment, and PTS were measured. Statistical analyses included t
