this may seem like an insignificant question but I was wondering if the new knee replacement would weigh more than our knee joint they took out.  It seems like it would.

thanks

      But a lot of implants are made of a cobalt-chromium alloy and not titanium.  Cobalt-chromium alloys are hard, tough, corrosion-resistant, biocompatible metals while pure titanium is generally used in implants where high strength is not necessary.  Gotta talk to your doc about which one he/she intends to use and why.

    Depending on the vendor, a full knee replacement joint can weigh anywhere from 1 to 2 pounds...some may be a bit more depending on how much of the original bone is cut away and the spacers required to fill the gap.  The original bone should weigh less than that of its replacement which, after all, is a mechanical device made of metal.

    I will have to ask my doc next week what he used.  I guess a couple of pounds is worth having a brand new working knee😊

    Hi Robin. Di in Australia. My knee is titaniam and my surgeon said weighed between half to one kilo, one and a half to 2.2 pounds, depending on thickness and size of the joint. There are 35 sizes as a tiny ladies knee would not fit a big man. He used a GPS to position the knee.

    Do you realise you are no longer weightless when swimming and also your knee gets cold in the winter from the inside. Some night pain may be caused by this.

    Good luck..i am 12 weeks post second knee.

    It certainly feels as if it weight about a hundredweight to begin with . . . like a block of cement!  I believe it actually is a bit heavier, but I wouldn't swear to it.
