Authors: Guoqiang Zhang


Obesity has become a global issue of public health, and the percentage of obese population has been increasing with the advancement of the society and its quality of life. The world has paid much attention to the health-related problems caused by obesity. The number of obese patients in need of knee replacement procedures is increasing as well. It is estimated that up to 50% of those receiving knee replacements will be obese patients by the year 2030. Obesity influences the outcome of knee arthroplasty in many aspects. Research has revealed that obesity could accelerate the development and progression of knee osteoarthritis, and bring forward the need for joint replacement for as much as 7 years (1).
