Yes, exercise can contribute to cartilage health and potentially stimulate some degree of regeneration. While cartilage doesn't regenerate as readily as other tissues, the right type of exercise can positively impact its health.
How Exercise Benefits Cartilage
Several studies indicate that appropriate exercise can improve cartilage health in a few key ways:
-
Increased Cartilage Turnover: Research shows that exercise, specifically joint loading training programs, increases cartilage tissue turnover. This doesn't necessarily mean complete regeneration of damaged cartilage, but it does suggest increased activity and potential repair at a cellular level.

-
Stimulating Stem Cell Activity: Exercise enhances the recruitment of bone marrow-derived mesenchymal stem cells to the joint, and increases their activity. These cells are crucial for tissue repair and regeneration. Source: Exercise as an Adjuvant to Cartilage Regeneration Therapy - PMC
-
Piezoelectric Stimulation: Exercise generates small electrical charges in the cartilage (piezoelectric effect), which has been shown to stimulate cartilage regeneration.

-
Strengthening Joints: The right exercises build up cartilage, making the joint stronger and less prone to damage. This preventative effect helps maintain existing cartilage and reduces the risk of further damage.

Limitations
It's crucial to understand that exercise alone may not fully regenerate severely damaged or lost cartilage. While it promotes health and potentially some repair, it's not a replacement for other treatments like surgery in cases of significant cartilage loss.

Also, the type of exercise is crucial. High-impact activities might exacerbate existing damage. A physical therapist can help determine the appropriate exercise regime for an individual's specific needs and condition.
Conclusion
Exercise plays a supportive role in cartilage health, potentially stimulating some regeneration and certainly improving overall joint function. However, it's not a standalone solution for significant cartilage damage.
