Could this complication be due to an allergic reaction?

Women may be at higher risk of complications after hip and knee replacements due to higher rates of hypersensitivity to the metals contained in their implants, a 2017 study suggests.

The study, published by The Journal of Bone & Joint Surgery reviewed more than 2,600 cases of patients who had unexplained joint pain after a hip or knee replacement. None of the participants could associate their post-procedure pain to an explainable reason such as infection. The study suggests one reason women may be more likely to have complications is due to allergic reactions from the metal in their joint replacement.

Prior to patient blood testing, 29 percent of the females studied said they had an allergy to metals, compared to 4 percent of men who responded the same. However, blood tests revealed that 49 percent of the women showed signs of immune sensitization – a predisposition toward developing allergic reactions based on environmental triggers like an implant. Only 38 percent of men had signs of immune sensitization present.

Women also had higher average pain scores than men. They averaged 6.8 on a pain scale of 10 versus men at 6.1.

“The occurrence of metal sensitivity in patients undergoing joint replacement surgery is relatively uncommon,” says Dr. Arif Ali, an orthopedic surgeon at Advocate Lutheran General Hospital in Park Ridge, Ill. “Therefore, routine screening for metal sensitivity is not an accepted standard of care. Patients who report a history of skin reaction to metal jewelry are screened before their procedure.”

Dr. Ali says that male or female patients who have documented metal sensitivity can still undergo joint replacement.

“Some joint replacements are manufactured without certain metals which are most commonly the offending allergen, such as nickel.”

    I am going through right now, in fact I’ve had pain, inflammation and rash. I was never checked for an metal allergy. Many tests MRI and Scans and no one can tell me why I’m having itching, pain and swelling of my knee implant. Repair of the meniscus was done first, didn’t last, thats when I had the replacment 2011. Things have not changed, I”m itching, swelling, numbness and pain, after all this time. Can you help me?

  3. I had a dental implant a few months ago. I expressed to my oral surgeon that I have a history of metal sensitivity and I wanted to be sure I would not have an allergy prior to agreeing to have a dental implant procedure. I did my own research and found the MELISA test for metal sensitivity. I had the MELISA blood test done, and my test result was negative across the board – I did not have any sensitivities to the multiple metals that are in a dental implant. I confidently had my dental implant procedure, and have had tremendous results!
