Patients with obesity who undergo knee or hip arthroplasty (joint replacement surgery) are at an increased risk for post-operative complications, including problems with wound healing. Those who are obese tend to have higher cytokine levels (cell signaling molecules) indicating the existence low-grade inflammation in this population.
