Risks of endoprosthetic replacement of large joints in patients with obesity

Abstract

In developed countries, people are increasingly suffering from overweight and obesity. Today, in the world there are about 1.6 billion people whose body mass index (BMI) is greater than 25. Simultaneously with this "non-infectious epidemic" there are also rising costs for global health for the treatment of obese patients. A particular problem of this category of patients is for orthopedic surgeons. And obese patients are the every second person which according to statistics will inevitably become obese in his life. Being overweight is dangerous from the standpoint of the operation to replace a hip or knee replacement. There are many risks, as well as rising costs for the surgical treatment of these patients. Operation arthroplasty is becoming increasingly the treatment of choice in the treatment of diseases of large joints. However, this benefit is associated with a high risk of re-intervention, and often in the early stages. The main reason for failure is aseptic loosening of the implant. This article describes a complex clinical case of one of the possible complications, which we had to face in our practice of knee arthroplasty in obese patients.
