Mastering Meniscus Basic Science & Biomechanics: Orthopedic Board Prep MCQs

Key Takeaway

The menisci primarily consist of longitudinal (circumferential) type I collagen fibers, essential for converting vertical compressive knee loads into 'hoop stresses.' These stresses are then efficiently resisted by the circumferential fibers, allowing the meniscus to transmit load, absorb shock, and protect articular cartilage. Radial fibers act as tie-ropes, enhancing structural integrity.
