The Knee's Vulnerable Position Knees sit between hips and ankles, absorbing forces from above and below. When hip or ankle mobility declines, knees compensate. Most knee problems are not knee problems. They are hip or ankle problems that manifest at the knee. These five signs indicate your knees need attention. The 5 Signs 1. Pain During or After Stairs Stair climbing and descending loads knees heavily. Pain with stairs indicates joint stress that exceeds what healthy knees tolerate. This early sign deserves attention before damage accumulates. 2. Swelling After Normal Activity Knees that swell after walking, standing, or routine activity are inflamed beyond normal. Swelling indicates irritation that healthy knees do not experience from basic use. 3. Grinding or Crackling With Movement Crepitus, the grinding or crackling sensation during knee movement, indicates surface changes in the joint. While not always painful, these sounds signal changes that may progress without attention. 4. Instability or "Giving Way" Knees that feel unstable, that occasionally "give way" during walking or standing, indicate weakness or structural issues that need assessment. Instability increases fall risk and suggests underlying problems. 5. Stiffness That Limits Bending Full knee flexion allows heel to touch buttock. If this range has decreased, if kneeling has become difficult, knee mobility has declined. Progressive stiffness indicates changes that warrant attention.

Each rep, try to find more space to move your leg higher - but don't force anything. Listen to your body and find what works for you. Ankle Mobility JME 104 Sitting in your chair, rotate your upper body to one side and extend one arm back. Hip Flexor Stretch JME 144 For stability, hold onto your chair or desk with one hand. Follow the movement of your leg to the diagram very specifically. Ultimately, you are making a big circle with your knee. You want to be finding your end range of motion at each point. Be slow and controlled - this isn't a race. Find what works for your joints. Protecting Knee Health Knee health depends largely on hip and ankle function. Addressing the joints above and below the knee often resolves knee symptoms more effectively than focusing on the knee itself. Full chain mobility protects the knee.
