Collagenous Ultrastructure of the Discoid Meniscus: A Transmission Electron Microscopy Study.

Background: The collagen ultrastructure of the discoid lateral meniscus (DLM) has not been precisely defined.

Purpose: To investigate the ultrastructure of the DLM, focusing on its collagen fibers, and to compare the collagen net architecture between intact and torn DLMs using the Collagen Meniscal Architecture (CMA) scoring system.

Study Design: Descriptive laboratory study.

A Comparison between Clinical Results of Selective Bundle and Double Bundle Anterior Cruciate Ligament Reconstruction.

Purpose: The purpose of this study was to compare the clinical outcomes of arthroscopic anatomical double bundle (DB) anterior cruciate ligament (ACL) reconstruction with either selective anteromedial (AM) or posterolateral (PL) bundle reconstruction while preserving a relatively healthy ACL bundle.

Materials And Methods: The authors evaluated 98 patients with a mean follow-up of 30.8±4.
