I had hyperextended knees all my life and never knew it until my orthopedic surgeon told me after first TKR. He said my knees would look different bc he couldn’t put the new ones in like mine were or they would break. It has been recently been suggested by Mayo drs that I have hEDS. Since having both knees replaced. I’ve had back, hip and foot pain and issues walking very far. It’s like my body doesn’t know what to do with these knees! Anyone else?
