How to Improve the Strength of Your Knees

Knowing the underlying cause of weak knees helps determine the treatment. Following remedies can help improve the strength of the knee-joint.
  • Knee exercises performed under the guidance of your physician may help relieve the pain. Regular exercise promotes easy movement of the joint.
  • Ice packs and heat pads applied around knees offer pain relief.
  • Wearing knee pads and perfect shoes helps reduce the pain.
  • Massage with essential oils and application of balm or herbal pack help lower the pain.
  • If you are overweight, you should try to get rid of those extra pounds by following a weight loss diet. Reduced weight helps lower the burden on the knees. This helps lower the pain.
  • The 'acute inflammation' may subside gradually, with sufficient rest. This is the simplest way to relieve knee pain, if the symptoms are mild.
  • A balanced diet which provides all the essential nutrients in correct proportions is essential to maintain the health of the muscles and joints in the body.
  • You may take non-steroidal anti-inflammatory medications, commonly referred to as NSAIDs, prescribed by your doctor. These medications work great for knee pain caused by health problems like arthritis, bursitis, and tendonitis.
  • Cortisone is a powerful medication used to treat inflammation. Let the doctor decide whether taking cortisone injections is essential.
  • If nothing works, the doctor may recommend knee replacement surgery. Such surgeries are quite common, these days. After the surgery, rigorous physical therapy is necessary to achieve the goal of full motion and strength.
