Running & Joints

QUESTION: Does running cause arthritis (will it "wear out" my joints)?

ANSWER: Running (or other repetitive impact activities such as step class or aerobics) will not damage the surfaces of a NORMAL joint. Previous injuries (fractures involving the joint surface, meniscus cartilage surgery, ligament injury), abnormal joint alignment, muscle imbalance/weakness may alter the ability to tolerate certain types or amount (frequency) of load and CAN lead to degenerative changes over time. Soft tissue problems (tendinitis, bursitis, inflammation of the joint lining), however, are not uncommon. Attention to flexibility, muscle balance, and GRADUAL increase in running time or distance will avoid most problems. Persistent joint swelling with activity is worrisome and merits medical evaluation.
