Joint Replacement Runs Low Among Male Smokers, Study Says

Smoking is considered to be a bad habit by most of us due to its unhealthy effects to the human body. However, according to a study that has been published online in Arthritis & Rheumatism, male smokers were less likely to go through a total knee or hip replacement implant operation than those who never smoked.

Study author George Mnatzaganian, a PhD student from the University of Adelaide in Australia, said in one of their press statements that “Our study is the first to demonstrate a strong inverse correlation between smoking duration and risk of total joint replacement. The independent inverse associations of smoking with risk of total joint replacement were evident also after adjusting for major confounders and after accounting for the competing mortality risk in this elderly cohort of men.”

One of the reasons for which a man or woman may undergo a joint replacement operation is because of osteoarthritis. It is the most known type of arthritis. Almost 27 million Americans are afflicted with this degenerative condition.

Osteoarthritis is also called the wear-and-tear disease as it happens when the protective cartilage on the ends of your bones wears down in the long run causing pain and stiffness on the joints.

A joint replacement operation is the last resort of osteoarthritis patients when they cannot handle the pain anymore. It is an elective surgical procedure, although doctors may suggest it but in the end it is the decision of the patient that matters.

In the Health In Men Study (HIMS), Mnatzaganian and his team were able to gather medical records for 11, 388 men, and they found out that 857 of them had joint replacement surgery upon their primary assessment.

During the evaluation of the participants, they were classified by age groups. There were three age groups – 65 to 69 years old, 70 to 74 years old, and 75 years and above. Among them, 41 percent had total hip replacement while 59 percent experienced total knee replacement.

According to the Agency for Healthcare Research and Quality, almost 285,000 total hip replacements are done every year in the United States, on the other hand, 600,000 knee replacements are performed yearly as well. Statistics show that more and more osteoarthritis patients succumbed to replacement surgery.

Based on the results of the study, overweight or obese patients increased their chance to go through a joint replacement. However, those who have been smoking for almost 23 years are less likely to undergo a joint replacement. In addition, those who smoked for nearly 48 years were 51 percent unlikely to have a joint replacement operation than non-smokers.

Although joint replacement operation is considered to be the most successful orthopedic procedure, complications still exist such as inflammation, pain, and metallosis. Know more about these complications and other news about joint replacement here,
