What exercise plan would you recommend for a senior citizen with two knee replacements and limited mobility due to pain?

Quadriceps Sets
• Activate your thigh muscles
• Try straightening your knee.
• Keep holding for five to ten seconds.
• This exercise should be repeated approximately ten times in two minutes, followed by a minute of rest.
• Keep moving until your thigh feels fatigued.

Straight Leg Raises
• As with the quadriceps set above, tighten your thigh muscle while fully straightening your knee.
• Lift your leg several inches.
• Hold for 5 to 10 seconds, then slowly lower.
• Repeat until your thighs feel fatigued.
You can also raise your legs while sitting. Your knee should be able to straighten when your thigh muscles are completely tight.
• Keep doing this.
• Keep doing this periodically until full strength returns to your thigh.

Ankle Pumps
By contracting your calf and shin muscles, move your foot up and down rhythmically.
Exercise for 2 to 3 minutes twice or three times an hour in the recovery room.
If you have ankle or lower-leg swelling, continue this exercise until you fully recover.

Knee Straightening Exercises
• Make sure your heel doesn’t touch the bed by placing a small rolled towel above your heel.
• Keep your thighs together.
• The back of your knee should be in contact with the bed after fully straightening your knee. Keep it straight for 5-10 seconds.
• Repeat until you feel fatigued.

Bed-Supported Knee Bends
• Keep your heel on the bed by bending your knee and sliding your foot up toward your buttocks.
• Bend your knee maximally for five to ten seconds, then straighten it.
• You can repeat this several times until your leg becomes fatigued or when you can completely bend your knee.

Sitting Supported, knee bends
• If you are sitting in a chair or at your bedside, place your foot behind the heel of your operated knee.
• Begin to bend it as far as you are able.
• Stay in this position for five to ten seconds.
• Continually repeat until your knee can fully bend or your leg feels fatigued.
