This study aims to test the hypothesis that cartilage thickness would be significantly affected by the load bearing conditions in the human knee. Six healthy knees were scanned using magnetic resonance imaging. Three dimensional models were then created using computer software. Localized cartilage thickness analysis was then performed at various load bearing and non-load bearing regions. Load bearing regions were found to be 43% thicker than non-load bearing regions in the femur and 53% thicker in the tibia. In the patella, load bearing regions were found to be 33% thicker than infrequently olad bearing regions. All of these differences were statistically significant (p<0.05). Load bearing condition has a positive correlation with the thickness of the cartilage in human knees. A certain level of moderate dynamic loading experienced in daily activities may be the ideal biomechanical condition for cartilage maintenance.
