Elevate your leg and use a kitchen chair to sit in. Then exercise your arms with weights or cans of food for weight. I have even used potatoes in shopping bags. Do arm circles, lifting up and down, on your sides and in front. With elbows bent put your hands behind your head and lift up and down. Do 10 at a time for 10 reps. For the leg do straight leg lifts, also from straight leg pull back to chest then back straight again. Foot, straight leg through all, hold about 3" off floor, point toes and foot as far forward as you can then pull back as far as you can hold for a count of 3. 10 reps. Do circles in both directions, I hope that helps. Good luck.
