A recent meta-analysis (a study combining results of many studies) has confirmed that patient smoking and surgery are a bad combination. They demonstrated in smokers hip replacement have 3.7 times the infection rate, 3 times the rate of joint replacement loosening, and 2.6x the risk of revision surgery compared with non smokers.
It has been known for a long time that smoking reduces the success in non union and infection related surgery to a point that the surgery probably shouldn’t be attempted. Ironically, the cost of smoking for a year in Australia is about the same as a year of private health insurance.
