    Whenever I run, I realize I end up putting more strain on my left knee. Does anyone have a suggestion to avoid this?

    There could be a number of reasons but we can't see how you run. Some runners have an insert that they place inside one shoe (which is custom made for their foot) to balance their legs. I wear a band on one knee to stablize it when I do long distance runs. There are other alternatives. My advice for you is to make an appointment with a physical therapist. (Your doctor should be able to recommend one or just google "Philadelphia physical therapist".)They will watch you walk/run and test your flexibility. I see that you're doing yoga. That should help. Are you doing it weekly? Do you find the similar stress in certain yoga positions? Hopefully the therapist can make an appropriate recommendation for you. Good Luck.

    Well, I'm a guy that's been running 50-75 mile weeks since the 1970s. This is very common, and you should see a podiatrist.

    And, no, you don't need to quit running...right out of the 1960s school of athletic sports medicine.

    Most of the guys in my club, which is oriented to racing, have orthotics custom designed by a podiatrist who knows runners/triathletes.

    The issue is that most of us have small leg length discrepencies....that don't cause a problem if you don't run or don't run much. But the longer you run over a longer distance, the more that leg length (or other issue) can cause torquing to occur around the knee, or ankle or hip. You'll end up with muscle strains, sciatic, and all sorts of other inflammatory issues because of that.

    The orthotics just don't go in one shoe. They are designed to give you a neutral foot plant (meaning, unpronate the pronators, unsuppinate the suppinators, level out the playing field for leg length discrepencies etc.

    It's not a scam and there is excellent science behind this. So my advice is to get to a podiatrist who knows athletes and DON'T just buy Dr. Scholl's inserts...because you have no idea what's causing the problem, exactly.

    Good luck with that.

    Wow, Fastprof said it all right there.
    Although I have never done the orthotics, I know that I should for my left shoe. Actually one leg shorter that the other is pretty common. (my left)
    Having done my share of long distance running, I do suggest to anyone to make the trip the a better athletic shoe store and be fitted to the correct shoe for you. As John said. unsuppinate the suppinators and unpronate the pronators!
    Happy Running. Great way to keep the fat off the middle.

    thanks for the suggestions. I do have a slight discrepancy in leg length. I will talk to my doctor about this. Again thx a lot for the suggestions, its very helpful.

    When I do Yoga, I don't experience it. Even when I do short run 3-4 miles on treadmills I am fine. However, in the last week in final prep for the 10K race, I was running much more. Thats when it started bothering me more; but I still finished the broad street run.

    That is a short distance for that to be bothering you. Get to the shoe store and your doc.

    as a endurance coach. check out if there is a chi running group in your area,; for orthotics go to they are the best. i have been wearing them for 15 years, of course not the same pair, i get new one's every two years. also check out the new running shoe Newton at, super nice shoe. definitely worth the price, because they last 25% longer than the other brands, no kidding.

    There can be many different reasons why you feel it only on your left knee...

    As you already mentioned, you have a leg length discrepency.

    However, did you know leg length discrepency comes in 2 flavors: anatomical and functional.

    Anatomical is the actual bone length. No one is exactly symetrical but above 1/4" can be felt by some patients.

    Functional leg length discrepency is caused by a rotated and uneven innominate (pelvic bones.) If one half of the pelvic bone is somehow tilted forward, the socket of the thigh bone would drop a bit lower and functionally be longer. If you have this condition, you would also likely have lower back pain and sacroiliac pain as well.

    Beyond leg length discrepency, the various joints in your feet can also have an affect on how the knee joint is loaded. The ankle is actuall 2 joints: The talocrual and calcaneal/subtalor. The subtalor can slide sideways too much, causing the entire ankle to lower. The mid foot nacivular joint can alos drop causing a pronated/flat foot, this will cause tilt and rotation of your tibia/shine boen and load your knee the wrong way as well.

    Then there is the shape of the joint and the long bones involved. Are you knock kneed, bow legged, the list goes on.

    Go see a GOOD PT and have a gait analysis done.

    Some of the conditions are corrected by shoe wear, shoe lifts, orthotics, heel cups, bracing, training of proper running pattern, orif this problem is inthe pelvis, manual adjustments in conjunction to flexibility and strengthening of specific muscle groups (likely flexibility of the ITB & hip flexors and strengthening of the gluteous meds and VMO)...

    I also have to point out:

    What did you mean "strain" on your left knee?

    DO you have an actual knee condition, which is aggrevated by the motion of running?

    The knee is 2 joints: the Condyle joints (the shine and thigh) and patellar (knee cap.)

    Knee cap joint problems comes in 4 flavors. There can be problems with the cartilage of the knee cap, the tracking and position of the knee cap, the knee cap tendon, and the plica or the synovial capsule folds.. Please refer to my post in the cycling thread:

    Then there is the condyle joint with the ligaments, capsule, meniscus, etc, etc..

    You could have a knee condition that is a result of the leg dicrepency or foot condition...

    always get your run shoes from a professional running shoppe. They know what to fit you in to correct a many of the ailments runners face.
