My wife and I just saw her surgeon yesterday. Her knee was replaced in June of 2021. Our Pastor even asked her about two weeks ago as she walked by if that was her shoe making that noise. That’s when she finally gave in to my insisting she get it checked out. X-rays from yesterday, no change from last years. Surgeon has never heard of this happening a year after surgery. He did notice she has very tight hamstrings. He is consulting with his fellow knee and hip specialist. We have total confidence in him. She starts PT next week hoping this brings some improvement. Praying you get an answer too!
