I had my surgery and reconstruction in January 2018. My leg healed quickly and with physical therapy I was able to get back to most physical activities after 6-8 weeks. I thought the radiation treatment was more difficult than the surgery. I was standing with a cane after the second day and walking with a cane on day 3. I was physically active prior to my diagnosis so I’m sure that helped with my recovery. Wishing your dad a speedy recovery!
