Lower body training after broken ankle

[whidor]

Just started weight training again (3x/wk) & cardio (3x). I am now about 60# more than I want to be at 5'4". I have a very definite pear shape. The dilemma is that I broke my ankle last Oct. (needed 2 surgeries to repair–has plate on one side/pins on the other. Squats, lunges and calf raises are difficult (even painful). Can anyone suggest variations or alternatives to the standard lower body exercises that don't require so much flexibility in the ankle area? Leg curls, extensions & toe presses don't seem to be enough over the long haul. I have a bit of equipment at home (bench with leg attachment and a standing abductor/adductor machine) and would prefer to do it there, but also have a gym membership.
