Nevertheless, some well being circumstances, together with weight problems, can put you in danger for problems with therapeutic after one of these surgical procedure.
We requested Stephen Engstrom, MD, an grownup reconstruction surgeon with Vanderbilt Orthopaedics, to elucidate what makes somebody a candidate for joint substitute, and the way those that don’t meet the factors can work towards that purpose.

“With each affected person who comes into my workplace with a BMI over 40 and different medical comorbidities that I feel would make joint substitute unsafe,” Engstrom added, “I ensure that they’ve a referral to the burden loss middle and that they’ve a follow-up appointment with me. I allow them to know that the factor that’s actually going to assist their joint ache probably the most goes to be the joint substitute, however the hot button is doing it as safely as potential.”
Is a BMI of 40 or increased a strict barrier to surgical procedure?
The danger of problems does go up considerably with a BMI over 40, Enstrom stated. However that’s not all the time a deal-breaking quantity. Threat additionally will depend on total well being. “If somebody comes into my workplace and their solely medical comorbidity is that they’ve a BMI of 41 or 42 — they don’t have diabetes, they’re a nonsmoker they usually don’t have coronary heart illness — then I feel that locations them in a suitable danger class,” he defined.
