If both knees need to be done do one knee at a time. You need the other knee for rehab. The key for a normal return is to religiously do the rehab. Generally what you get in range after 30 days of rehabilitation is all the range you will get. I wouldn’t recommend a partial replacement. Get a total knee replacement. Find an orthopedic surgeon who does a minimum of 300 knees per year.
