Anatomy and Physiology of Knee Stability

TLDR

Knee instability remains common despite extensive research, because stability depends on a complex integration of anatomical structures and physiological mechanisms, and compromising any of these increases injury risk. The report examines knee joint anatomy and physiology, highlighting structures and soft tissues that contribute to stability and function. The authors review the knee’s structural and soft‑tissue components that provide stability and function. This introduction appears in the Journal of Functional Morphology and Kinesiology’s Special Issue “The Knee: Structure, Function and Rehabilitation.”.

Abstract

Knee instability has been the focus of large number of studies over the last decade; however, a high incidence rate of injury still exists. The aim of this short report is to examine knee joint anatomy and physiology with respect to knee stability. Knee joint stability requires the integration of a complex set of anatomical structures and physiological mechanism. Compromising any of these structures leads to destabilisation and increased risk of injuries. This review highlights the structure and soft tissue of the knee that contribute to its stability and function. This introduction is part of the Journal of Functional Morphology and Kinesiology’s Special Issue “The Knee: Structure, Function and Rehabilitation”.
