You will NOT necessarily need a cane!!!! I was going up and down stairs in 4 days. Using both legs. It has been 18 days since surgury and I was doing squats and lunges(with no weghts) this morning with no pain. It gets a little sore, but I dont even need tylenol!! You wont be moving much anyway the first week, so pain from walking wont even be an issue. Using your own bone is considered "the gold standard." Dont you deserve whats best for your body?
