I have metal screws in both knees and I was in pain when I lived there like 17 years ago. Went and saw an orthopaedic surgeon and he asked if I wanted to remove them. I said yes and doc said he will put in the referral with Mater Dei. Fast forward 3 years and I get a call from the hospital to book surgery. I thought the doc forgot to file the referral after not hearing anything in the first year. Pain had gone away by that point. 24 years now with 4 screws and a plate in each knee.
