Normal Knee vs Damaged Knee! In a healthy knee joint, there’s a clear gap — that’s the cushion (cartilage grease) between your bones. But when this gap disappears, the bones start scratching against each other. That’s why you feel pain, hear cracking sounds while climbing stairs, or even face knee locking. 👉 If your knees feel tight, painful, or make noise — don’t ignore it! The more it rubs, the closer you get to joint replacement. I’ll show you how to stop that damage before it’s too late. |
