My wife in 2022 had to have a total hip revision because she had two staph infection and chromium / Cobalt poisoning, in addition to a loose stem! You describe exactly what she had done! They had to put in a medicated spacer for 8 weeks along with antibiotics. I’m feeling this would be your worse case scenario. Three months out with groin pain is not that uncommon. Hopefully Physical Therapy and / or Home Health are working with you! My wife had her surgery at Dartmouth Hospital in New Hampshire. This made her 6th hip implant! She had both done at the same time in 2011, 2012 she had a revision on her Right because she was dropped on the shower floor in Rehab but the could not do the revision until the femur nerve woke up on her left from being compressed. In 2018 she had her Left hip replaced due to the Cobalt / Chromium poisoning and then in 2022 a complete replacement. I’m sure you will do just fine! One thing ! Have your vitamin D levels checked and have them check for Chromium / Cobalt levels! Her orthopedic surgeon declined so I had her primary check them and shared the results with her orthopedic surgeon! I’m sure my wife would be willing to share her experience with you should you feel the desire! Today, she has very little pain in her hips! She was vitamin D deficient which lead to fractured vertebrae in her lower back; I questioned if this was also caused be the continued injection in her back to numb her from waist down and they say, no, who know for sure?
Not trying to scare you, you will get through this, just be a strong advocate for yourself! Ask Questions and be sure to get answers! Hopefully they put ceramic coated implant!
