Oxinium Knee Replacement - HealthClues

The company said yesterday that it had stopped sales of the cementless versions of two of its knee systems because of a higher than expected number of follow-up operations.According to a Smith & Nephew spokesman, about 30 of the 3,000 patients fitted with cementless versions of its Oxinium Genesis II and Profix II implants in the US have needed to have the procedure revised after the implants became loose.

Mr Rees is one of a few surgeons in the UK currently using a revolutionary new material called oxidised zirconium also known as oxinium. Oxinium is produced as a result of a chemical process that allows oxygen to absorb into zirconium metal thereby changing only its surface from metal to ceramic. This new material may be considered for young patients (under 65 years of age) undergoing total knee replacement.

Knee Replacement - Implants Subject to Recalls, Lawsuits

I am at 4 months post total right knee replacement. I am doing well, but what they say is so true. It does take 6 months to a year to totally heal. New bone has to grow around the parts than extend down and up into the bones. This does not happen over night, I have found. I have good ROM now, but still have the stiffness if I don’t rest often. Still have a catchy pain at times when moving the knee after sitting for awhile. I no longer have to prop my leg when sitting. Finally have been able to stop using the ice as the swelling is gone. I am 73 so I can afford to rest when I need to. I am still very active and healthy. Patience is the word to put at the top of the list after a surgery of this kind. My thoughts and prayers are with all of you that just had surgery. The surgery is a piece of cake, its the long long recovery and the physical therapy that is the pits. But it is well worth it in the long run.

Smith and Nephew Oxinium Genesis II and Profix Knee …

I guess God blessed me although I did not feel that way the first few days as the pain was terrible. I had a bilateral total knee replacement on April 29th, 2013. I am 58 yrs old and weigh in around 205-210 and am 6’3″. I came home on day 4 as day two they left in the nerve and pain blocks but by 10 the next morning I walked about 100 feet. I do believe that the pre-op exercising of the legs is by far the biggest thing that gets left out site after site. I worked quads, hams, and inner and outer legs for 3 days a week hard maxing out on the 3rd set of each exercise and limping out of the gym due to my left leg being so bad ( my fault I kept putting it off and playing basketball with my 2 sons 21 and 24) but within 10 days I was walking with no aid at all around the house..doing the therapy was murder but it is temporary where prior to it was forever, right. Stretch those knees, make it hurt and hold it there for at least 20 seconds if possible or work up to that. By day 14 I had walked 3 straight days of 1 mile in about 35 minutes. At end of week 3 I was able to walk 3 miles without stopping in 1 hour and 30 minutes thought right leg did swell some I propped it up and iced it with some ibuprofen, ( was off all pain killers except otc by day 14.) I was back at work after 4 weeks and I am just past week 5 and every hour or so I walk for 2-3 minutes and do 2-3 hard knee bends with each knee for 20-30 seconds and am walking the 3 miles in just over an hour, missing it by 3-6 minutes depending on day. My experience is that the harder you work bending or trying to improve the rom and walking to improve circulation and going to the gym and do light work know which pain is no good and to stop but do the quads, hams, and inner and outer legs too ( adductor and abductor machines ). On the first day of week 3 my ROM was 107 for the left and 103 for the right ( which by the way had the drain knocked out on way to recovery and never did get drained so the left drained 600ml while the right drained zero which explains why it is still tighter and does not have the ROM yet. I had 6 days of in house therapy and they sent me to out patient where I had one day and picked up a copy of their exercises and am doing this on my own. Does it hurt… only during therapy..but its a good hurt as I know. One drawback is I do not know what my ROM is but 1 week ago I could not do the leg extension machine for my quads as the right leg could not get under the roller but within a week I can and though I was doing 240 10 times for a 3rd set before operation I am only at 100 lbs for 3rd set. Why no one tells you that you lose so much strength in your quads and hams etc is irresponsible…and the pre-op exercise routine should be so much more extensive and I think the post-op would be so much better for everyone.

replacement is called the Oxinium knee ..

I had a TKR in March, 2013. Was skin tested for metal allergies – still became allergic to Nickel in implant (BEWARE- be blood tested before TKR). Toxins sent me on downhill spiral and ended up with upper muscle loss, pain everywhere (still do) and had to have revision(10 months) in January 2014. I am so weak and so down…feel like end of the world. Suffer so much – no appetite and cannot take so many meds due to sensitive and allergic. On Warfarin so no NSAIDS to help inflammation -any suggestions as to what I could take, what I can do to help my cause. Any advice would be appreciated. Been in constant pain for year now – ready to give up but know that is coward’s way out. If anyone has some hope they might share……please do so. I really need some positive feedback – or any feedback. Did 6 weeks outpatient PT….got to 117 ROM – nearly killed me. Not going back but do work out at home. Trying the rocking chair. Cry so much, depression – have ruined my life. Never, ever any pain like this before surgery. Just needed new knees – bone on bone and wanted before I got any older. I am 72 but was a hard working 72 – know family, friends hate to even call me. So many prayers out there for me. Please, please help me if you know any solutions to any of this including gaining appetite back once again. God bless each of you suffering with TKR pain or any pain. I know HE cares. I want my life back and pain gone. Can walk less than 10 minutes….cannot stand to cook, shop, etc. Have not cooked a meal in a year now. Bless my precious husband….he is my life now. Xrays look ok this time but they did before. Did not find allergy until Metal LTT Analysis testing in Chicago. Told them I could not wear nickel earrings…did not know they put nickel in until I got so bad and asked. Insisted on other testing. Was devastated when knew I had to have revision. Anyone had revision – how did you do……any revision due to allergy. Would love to hear. This sounds like a book – could not write anything this bad if I tried. Again……God be with all of you.
