A new study has found that obese patients tend to have a longer recovery time and worse mobility after knee surgery.
Researchers at the Hospital for Special Surgery in New York City analysed data from 309 patients who had undergone knee replacement surgery and found obesity was associated with a decreased range of motion after surgery.
In addition, obesity prolonged recovery and the need for physiotherapy, researchers revealed.
The findings were presented at the annual meeting of the American Academy of Orthopaedic Surgeons and lead author Dr Geoffrey Westrich noted that recovery time is important for patients undergoing knee replacement surgery.
Dr Westrich, who is an associate professor of orthopaedic surgery, said: "Patients often ask me if their pain is going to be relieved and if they will have better range of motion.
"Our findings will help set more realistic expectations for heavy patients. They need to be counselled that their weight will likely impede their recovery."
