Overview of Meniscal Injuries

Area of Science:

• Orthopedics
• Sports Medicine
• Anatomy

Background:

• The menisci are vital for knee function, providing stability, load distribution, and shock absorption.
• Meniscal injuries constitute over 60% of all knee injuries, affecting both athletes and non-athletes.
• Tears result from combined axial loading and rotational forces, with the medial meniscus being most frequently injured.

Purpose of the Study:

• To detail the anatomical significance of menisci in knee biomechanics.
• To classify common meniscal tear patterns and their implications for treatment.
• To identify potential diagnostic challenges in evaluating meniscal injuries.

Main Methods:

• Review of anatomical and biomechanical literature on menisci.
• Classification of meniscal tear types based on location and pattern.
• Analysis of common causes and contributing factors to meniscal tears.
• Identification of diagnostic pitfalls and anatomical variations.

Main Results:

• Meniscal injuries are the leading cause of knee trauma, frequently linked to degenerative changes.
• Tear classification includes horizontal (simple, complex, flap), vertical/longitudinal (simple, bucket-handle, ramp), and radial (simple, parrot beak, root tears).
• Diagnostic challenges arise from anatomical variants, surrounding structures, and imaging signal variations.

Conclusions:

• Meniscal anatomy is intrinsically linked to knee stability and shock absorption.
• Accurate classification of meniscal tears is crucial for guiding appropriate treatment strategies.
• Awareness of diagnostic pitfalls is essential for precise evaluation of meniscal injuries.
