As a shoulder and sports medicine orthopedic specialist, I would not recommend surgery for a proximal biceps tear, even in a high level athlete. As some others have suggested, proximal and distal tears are treated differently. The exception for proximal tears would be for patients or athletes who also have a rotator cuff tear. Even in that setting, though, we generally operate on the rotator cuff and leave the biceps. If you search hard enough, I have no doubt you could find an orthopedic surgeon to fix it, but most well trained specialists will appropriately recommend against it.
