[|Human|] I went to an orthopedic surgeon who told me my left hip was coming out of the socket. He also told me to wait as long as possible because of my age. I have two questions. When I walk, I get a sharp pain in my knee and my leg locks up for a moment. Is this normal for my condition? And, how do I know when the hip replacement is absolutely necessary?
[|AI|]  Hi their total hip replacement is indicated when your pain becomes so severe that it interferes with your daily activities and when common pain medications have failed to help relieve the pain and your hip function has becomes useless because of pain. All pain treatment modalities must be exhausted before thinking of doing a total hip replacement, and we like doing it for patients older than 50 years of age. A younger person might require a hip replacement when all other treatment options have failed to alleviate pain. Pain in the knee can be coming from a hip problem but your knee need to be examined as well by a doctor.
