Dr. Vallotton describes in detail functional hallux limitus, a mechanical disorder of the big toe influencing the entire postural chain.

This video provides an introduction to the functional assessments performed at the Ouchy Orthopedic Center. Dr. Jacques Vallotton explains how biomechanical disorders of the foot can impact the knee and hip.

In this fascinating exchange, Dr. Jacques Vallotton talks with anthropologist Yvette Deloison about original bipedalism and the anatomical discoveries that challenge the classic paradigms of human evolution.

Dr. Jacques Vallotton presents the functional impact of hallux limitus on human walking, in particular the imbalances caused in the sagittal plane.

Meniscus tears do not always require surgery. Today, preserving the meniscus is prioritized to prevent early-onset osteoarthritis.

Dr. Vallotton explains the fundamental role of the meniscus in the biomechanical balance of the knee. He uses clear analogies to show how meniscal tears disrupt joint stability and shock absorption.

This video reviews the anatomical and biomechanical basics of the meniscus to better understand the origin of lesions. It shows how distant abnormalities (hallux valgus, femoral rotation, etc.)

This lecture explores Functional Hallux Limitus syndrome, a foot pathology linked to the blockage of the long flexor hallucis tendon.

Dr. Jacques Vallotton provides a detailed explanation of functional hallux limitus, a little-known condition that impacts foot propulsion. He describes its biomechanical consequences, clinical diagnosis, and conservative and surgical treatment options.

Knee sprains are common among athletes, but not all are serious. Dr. Jacques Vallotton emphasizes the importance of making a proper diagnosis when choosing between conservative or surgical treatment.
