Im 8 weeks post op from total knee replacement surgery. On 7 weeks out had a manuplation on knee bent to 135 degrees from 90. This week knee is back to 98 degrees and pain swelling is new implant to big for my body?
Total knee arthroplasty (TKA) has a strong postoperative pain response. Postoperative pain will not only affect patient satisfaction and postoperative joint function recovery, but also lead to an increase in the incidence of complications. Epidural analgesia and femoral nerve block (FNB). For TKA, FNB is the preferred method, but may have insufficient analgesia. If the analgesia is insufficient, additional sciatic nerve block seems to be a reasonable choice; however, the advantages of conventional sciatic nerve block have not been fully demonstrated. A single block usually provides adequate analgesia for the first 24 hours; continuous FNB prolongs the analgesia time to promote functional recovery. For muscle strength reduction, by adjusting the infusion rate and local anesthetic dose, muscle strength can be reduced and the risk of falling can be reduced. Compared with regional analgesia (such as FNB), epidural analgesia has no advantage in knee surgery. Lumbar epidural analgesia risk is greater than Benefits, and peripheral nerve block can provide similar analgesic effects. Large-volume local injection analgesia has a low incidence of adverse events and less motor block, which may be a promising technique for postoperative analgesia after TKA. However, the formulation and capacity of analgesics remains to be further studied.
i agree.  Very confusing and goes in circles, never answering the question
Hi Linda, Carol's problem is the postoperative pain after total knee replacement. Lucas mainly answered the question that there are two pathways to resolve the postoperative pain: one is Epidural analgesia; the other one is femoral nerve block (FNB). He also analyzed the effect, advantages and disadvantages of both methods. He thought FNB is a better one to treat postoperative pain of the replaced knee.
I had a total knee replacement December 4th 2018. I still have swelling and pain. At times when I bend my  knee it feels as if it's ripping my knee skin. Is there a possibility that the replacement is too big for my knee? It is well big over my other knee that had no surgery. Yes I have small knee caps before the surgery. Help..
Have you see your surgeon for follow-up? have X-RAY test? I am not sure what is the your situation? you should see your surgeon and do test to find out.
I have had pain in both Trithlon knees for 13 years.  X-rays always report everything is fine mechanically.  The pain is constant and debilitating. I have 4-5 X-rays and several "rehab" sessions and the rehab folks say they can do nothing more.  No serious swelling, no redness, just constant pain. Sometimes a little feeling of instability.
Do an MRI instead of just X-ray.  X-ray is very insensitive
I am now working directly with Stryker and they are accumulating applicable medical records from all three facilities that have been involved with the installation and follow up.  That includes the hospital that did the installation and two medical groups that have done x-rays and follow-up rehab.  I think their interest is only in verifying that their product was manufactured and installed correctly. I hope they can help with the pain issue but an not helpful.  I expect the result will be the same as the various Ortho groups, "Looks just fine."
Have you done MRI?
I have the same issue after my TLKR in Jan. 2019.  Don’t think my patella is tracking.  Have extreme tightness and stiffness and pain on the inside by my kneecap when I bend my knee.  Exercise only makes it tighter.  My surgeon did a manipulation in Feb but even with aggressive PT couldn’t get flexion past 90 degrees.  My surgeon refuses to answer my questions.  Says the joint is fine.  My knee is locked.  Have seen other ortho specialists who want to do open lysine and manipulation or revision but are not optimistic about results.  Still seeking answers.
It's weird that you have good joint with these symptoms. Did you do knee MRI also? Are the ligament and tendon also fine? I am thinking it might be tendinitis
Your surgeon refused to answer your question because he was exhausted from possible causes and treatments. Is he quite experienced? If not, you should see a specialist.
I have seen several surgeons and have had multiple X-rays over the past few years.  I was able to walk the same day of surgery and climbed stairs that same day and walked completely around the the Green hospital complex in La Jolla the day after surgery, about a mile in total.  I was in a gown and had an IV with mobile support with me.  The guards stopped me once, thinking I was an escaped mental case.  

Both knees easily bend over 100 degrees and always have since the second day of rehab. There is a factor that I didn't think to mention. I have what used to be called Nocturnal Myoclonus, which now has a new name.  Apparently my legs kick st night and there is knee pain every morning.  That I understand.  What I don't understand is why my knees hurt later in the day when I walk and stand for some period of time.
I think it is also related to your nocturnal myoclonus. You need to see a doctor to see if this has progressed.

Nocturnal myoclonus treatment begins with correction of any underlying disease or condition. For instance, anemia is corrected by giving iron or folic acid supplements.

The intensity of the symptoms of nocturnal myoclonus can be reduced with changing the lifestyle. A balanced diet supplemented with vitamins and iron need to be followed. You should avoid food and drinks containing caffeine, such as coffee, tea, and chocolate. Moderate exercise can contribute to better sleep habits.
New Question: I have developed hives and total body itching after my replacement. Can you help me to resolve this. My allergist needs to know the composition of my triathlon knee. is there a package insert that will tell me the knee components ?  thanks
26 days out of surgery from total left knee replacement still have pain and discomfort so much swellingin knee area and can't bend the knee I can stand with walker move around with walker the cut(scar);is really nasty looking this replacement was done at the VA hospital in Atlanta yes I'm worried I'll never gain my bend back someone please shoot straight with me will I gain at least 90-95 percent of the bend Thanks Ronnie
When there's heavy swelling it's hard for you to bend. Let's see how it comes when the swelling goes off. I think you should be able to bend then.
Milagros you should reach at least a 90/95 degree angle. I will make a month on September 12th that I had my TKR. N I'm at a 90/95 degree angle.. It still feels right but I work on it two times a week with physical therapy at home. I was in rehab in a nursing facility where I got intense physical therapy. God bless you n good luck ...
ABOVE ALL-DO THE RECOMMENDED THERAPY.  i went a3x week with daily therapy at home and within two wks walking with cane.  another two weeks and no cane.  i am now 2 months out and have complete use of knee.  DAILY exercises and ensure you are doing the them the correct way.  my therapist walked me through every exercise.  Keep those ice bags on the knee when swollen.  praying you be back to normal soon.
