Hi there-
I needed a Bicep Tenodesis-it primarily fixes a torn
biceps tendon or one w/damage or instability. I was fortunate, had a great Dr in Boston, MA. It worked well and could go back to competitive softball and that is my throwing arm. In fact, that's how I hurt the bicep- it does take some force....I realize you had the replacement but it's likely that you may have injured the Bicep in PT or lifting since your surgery....Look for specialized shoulder Dr, 2nd opinion all the way.....Take Care.
