I struggled with my first hardshells on a slalom ski. Starts, performance, buoy count - everything but comfort. So I abandoned the hardshell idea (for slalom). I demoed a ski with Fogman hardshells and loved it. The boots had been ground so there was easy fore aft movement. So I tried my slalom hardshells again with no pins and some grinding to allow more forward movement and loved the hardshells after that.
Look carefully at your shells to see whether you can adjust or modify them to allow more forward flex. For the rear shell, a lot of people have removed the top cuff completely and there are factory offerings like that.
On another note, after hip surgery, I could barely get up. I was profoundly weak for a surprisingly long time. After an injury, you lose strength. Once you recover, too often you dial back the physical therapy. It takes a long time to rebuild strength. Get back with a physical therapist and follow the rehab program religiously. Getting up is actually very difficult and demanding of strength.
