Hello @tonycn, Welcome to Connect. It is good to do some research before undergoing any kind of surgery. You will notice we changed the title of your discussion a little to hopefully bring more members into the discussion who may have experience or information to share. @sueinmn @contentandwell and others may have some thoughts on which type of hardware may be better for a hip replacement.

Here is some information that I found on the topic that may be helpful.

"Which is better cemented or uncemented hip replacement? -- Modern fixation techniques and implants using cement have resulted in better outcome than older cemented and historical uncemented series. However, uncemented devices over the past 30 years have shown improved stability equal, in many cases, to cemented fixation." -- (2017) The Relative Merits of Cemented and Uncemented Prostheses in Total Hip Arthroplasty: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5525518/

Are you leaning toward one or the other of choices?
