I got a great, easy hip replacement in 2007. DePuy recalled hip ball and cup in 2009. Beginning of 2011 it began to disassemble!! Everyone in my medical ortho group with this experienced about 4 years til it began to reek havoc! I am now post recovery 3 weeks! I am walking, weight bearing on the hip etc. But I have a swollen knee and ankle. Just coping. Any advice send my way way. This is a great site!!!
