I appreciate your advice. I am service-connected for my original hip replacement. My symptoms included server pain and weakness in my right thigh of the right hip when weight bearing. It was replaced on February 2023 and my pain has lasted since a month after the surgery which was 13 months ago. I sought a second opinion and a bone scan was ordered and it showed that my entire arthroplasty was loosening therefore I would need a revision surgery to take care of my pain. I will undergo revision surgery on May 30th and I will submit for an increase in my ratings. Hopefully, I can go from a 90% rating to 100%. The temporary 100% rating for convalescent has changed from 12 months to 4 months for both hip and knee replacements. I will be requesting it as well once my surgery is complete. I will also submit for TDIU at the same time. Once again thank you for your advice it was very helpful.
