I had a bilateral knee replacement surgery in 2015 and have been in constant pain ever since. My surgeon suggested CRPS and I ve had from nerve blocks to Ketamine treatments and going to Europe for the drug Neridronate IV infusions, all treatment, were proven unsuccessful. I am now back with the surgeon after learning what I should have asked him before surgery: #1 Am I allergic to any metals #2 Am I allergic to any adhesive substances. I was never asked these two questions.In the surgery report it states all three components were noncemented . I have been allergic to adhesive material used in medication patches, some adhesive tapes. Is it possible the adhesive material used especially on the tibia plate could be causing my pain whenever I stand or walk? Appreciate your assistance,
Hello,First, since all components are non-cemented which means press fit to the bone and hence no adhesive material is used. Allergy to metal may be issue with many patients, but that will lead to knee effusion and local symptoms more than pain. Loosening of components and low grade infection may be reason for constant pain. Detailed knee examination and aspiration of knee joint fluid is required. X-ray of the both knee anteroposterior lateral and skyline views is needed to look for loosening of components. Please get this done from radiology center nearby you. Visit to your operating surgeon is needed. Hope I have answered your query. Let me know if I can assist you further.
