Tibiofemoral Cartilage Contact Differences Between Level Walking and Downhill Running.

ABSTRACT:

Background

Some studies have suggested that altered tibiofemoral cartilage contact behavior (arthrokinematics) may contribute to long-term cartilage degeneration, potentially leading to tibiofemoral osteoarthritis. However, few studies have assessed normal tibiofemoral arthrokinematics during dynamic activities.

Purpose

To characterize tibiofemoral arthrokinematics during the impact phase of level walking and downhill running.

Study design

Descriptive laboratory study.

Methods

Arthrokinematic data were collected on uninjured knees of 44 participants (mean age, 20.7 ± 6.6 years). Using a dynamic stereoradiographic imaging system with superimposed 3-dimensional bone models from computed tomography and magnetic resonance imaging of participant-specific tibiofemora
