Bone on bone knee how much should i walk each day?

What you can tolerat: Walk to your tolerance. Options: you can talk with your orthopaedic surgeon and get an unloader brace if the wear is on one side of the knee joint. You can get injections with cortisone every 3-4 months if it helps. Try a cane in the opposite side hand. Consider a partial knee replacement done robotically "makoplasty" if only one side is worn. Consider total knee if both sides are worn.

Use pain as guide: There is no magic mileage number. Simply use pain and swelling as a guide. Exercise should not just be about walking. Remember to do simple stretching and range of motion exercises regularly to maintain a full range of motion. Walking is good for cardio and strength, which helps maintain ideal body weight and prepare for any surgeries.

Arthritis: If your knee is really bone on bone i suggest avoiding walking for exercise. It will only cause more pain. Try a nonimpact exercise like biking or swimming.
