Bilateral occurrence and morphologic analysis of complete discoid lateral meniscus.

Purpose: The aim of the study was to investigate and analyze bilateral incidence and morphology of complete discoid lateral meniscus (DLM) with possible relation to tears and symptoms in knee joints.

Materials And Methods: Thirty-eight consecutive patients with symptomatic or already-torn complete DLM on magnetic resonance imaging in a unilateral knee underwent diagnostic arthroscopy on both knee joints upon agreement. The presence and shape of complete DLM as well as presence and pattern of tear were recorded accordingly.

Difference in knee rotation between total and unicompartmental knee arthroplasties during stair climbing.

Purpose: The purpose of this study was to compare knee kinematics during stair walking in patients with simultaneous total knee arthroplasty (TKA) and unicompartmental knee arthroplasties (UKA). It was hypothesized that UKA would reproduce more normalized knee kinematics than TKA during stair ascent and descent.

Methods: Six patients who received UKA in one knee and TKA in the other knee were included in the study.
