My husband had both knees done and his hips hurt, as well as his thigh muscles. Last year he had one side done, and same thing happened on that side but got better. This year, pain does not go away. He had physical therapy, even in the pool, to no avail. He had his last surgery back in September 2009. If you experienced the same thing, did it get better, and how. My question is addressed only to those who had it done, or those who know people who went through the same thing. Thanks.
