That’s great to hear! The expression “I feel like I have new knees” is often used metaphorically to describe the feeling of relief or improvement in mobility after a physical activity or a medical treatment that has made a significant positive impact on someone’s knees or overall well-being. It indicates a sense of rejuvenation or newfound energy, as if the person’s knees have been completely revitalized. Whether it’s from exercise, a medical procedure, or simply a positive change in one’s life, feeling like you have new knees signifies a positive transformation in your physical or emotional state.
