According to the American Academy of Podiatric Sports Medicine, one of the most common complaints of walkers, runners and joggers is knee pain. Knee pain while walking on a treadmill can stem from over-training, poor conditioning, inappropriate footwear or excessive pronation -- or rolling your foot in and down as you move on the treadmill. Consult your doctor if you experience persistent knee problems from walking on a treadmill.
Conditions
Knee pain usually is the result of overuse, poor walking form, failure to warm up or cool down or lack of stretching before using a treadmill. Knee problems can stem from arthritis, bursitis, tendinitis, knee dislocation, torn cartilage, a strain, sprain or a torn ligament in your knee. Knee pain also can be associated with connective tissue disorders including lupus. Overexertion on a treadmill also can result in runner's knee in individuals who over-pronate while they walk, jog or run. Runner's knee causes pain in the front portion of your kneecap near the thigh bone -- or femur.
Treatment
If you experience knee problems while walking on a treadmill, rest and stay off the treadmill until your symptoms subside. Ice your knee for 15 minutes at a time, at least four times a day. Avoid bearing weight and elevate your knee for the first 48 hours. An elastic bandage also can help reduce swelling, along with over-the-counter anti-inflammatory medication. Contact your doctor if pain persists after three days; contact immediately if you are unable to walk, experience severe pain, fever, numbness or notice a deformity in your knee.
Training
Overexertion on a treadmill can lead to pain and possible injury to your knees. Always warm up and stretch before a treadmill workout. Pay attention to your calves, hamstrings and knees while stretching. Additionally, start slow if you are just beginning a treadmill routine. Walk for a few minutes at a time and progress to 30 minutes a day, five days per week. If you become sore, allow your muscles a rest day to recover.
Footwear
Invest in a pair of running sneakers that fit appropriately to minimize pain and reduce risk of injury to your knees on the treadmill. There should be a 1/2 inch between the tip of your shoe and the top of your big toe, with enough room to wiggle your toes in your shoes. Replace your shoes if they become worn or damaged. Sneakers need shock absorption to help take some of the stress of treadmill use off your knees. Visit a running shoe store to consult with a professional to help you pick out the appropriate shoes for your treadmill routine. Individuals with flat feet can consider the use of an orthotic device to help your foot remain stable and avoid additional stress on your knees.
