How long does it take for a 57 year old over weight man to recover from major knee surgery for a ruptured tendon in the knee and a fratured patella?

Normally 6 to 8 weeks but because of the age , overweight could take longer. Therapy post surgery will help a lot, it could be painful, but no pain no gain, take some motrim before the exercises and full recovery will never happen, specially at this age. Don't forget loss weight and your cane.
