Combining protein supplementation (3-40g/day of amino acids/protein) with exercise training significantly increases muscle mass, muscle strength, and functional mobility while reducing pain in older adults with lower-extremity osteoarthritis, particularly those who have undergone total joint replacement.

If you are an older adult with knee or hip osteoarthritis, especially after joint replacement surgery, combining resistance or multicomponent exercise with protein supplementation (3-40g/day of amino acids or protein) is highly effective. This combination significantly increases muscle mass, improves strength, enhances mobility (walking, stair climbing), and reduces pain more than exercise alone. Aim for 2-7 weeks of consistent training with daily protein support to see these benefits.
