Can softening of cartilage be reversed?

Cartilage Healing: The articular cartilage has a blunted ability to heal. Softening of the cartilage is the first phase of cartilage deterioration. Clinically, there is no proven means to reverse the softening. However, there are theoretical possibilities to stimulate cartilage healing, e.g., electromagnetic, such as the ceruleau probe and bionicare knee system--i am not endorsing either product.
