Knee Joint Irritation: The knee can become irritated from injury, inflammation, arthritis, repetitive stress, or poor movement mechanics. This may lead to pain, stiffness, swelling, and reduced mobility.
Muscle Weakness or Imbalance: Weakness or poor coordination in the hips, thighs, glutes, calves, or core can change how the knee tracks during walking, stairs, squatting, and exercise.
Previous Injuries: Sprains, strains, falls, sports injuries, work injuries, and old trauma can affect knee stability, mobility, strength, and long-term comfort.
