!st MTP joint removal

Last year I had my 1st MTP joint of my left big toe removed and the bone fused. The toe was set in the optimum position for running,(so the surgeon said). Since the operation my left thigh muscles have slowly become tighter and tighter no matter how much I stretch. Also the wear on my left shoe heel is considerably more than the right. I have been told that this is all caused by the fact that I cannot "toe off" as before the operation. Has anyone the same problem and what if anything can be done about it.
