c. His history of anxious depression
Explanation:
Medical comorbidities like anxiety and depression pre and postoperatively will lead to suboptimal or poor functional outcomes after total knee arthroplasty.
Anxiety can increase the blood pressure which can lead to many postoperative complications after a TKA which in turn can result in poor outcomes from the surgery resulting in chronic pain.
A depressed patient will have a poor motivation to perform rehabilitative therapies in the postoperative period after TKA which are very vital for successful functional outcome of the operated knee. This also will lead to chronic persistent post-surgical knee pain.
Depression leads to dissatisfaction in the result after TKA which will make them feel pain.
Many studies have proved that anxiety and depressing will only lead to chronic pain syndrome among the elderly.
Nutrition is an important thing in regards to quality of life. With adequate nutrition your body will have the nutrients and vitamins that are vital in keeping the homeostasis of our bodies intact, and when this happens, you are feel good. However without adequate nutrition you are predisposed towards diseases that result directly from the lack of adequate nutrition (Like Bari-Bari if you lack Vitamin b12) or your body is inadequate when fighting illnesses like the flu because it doesn't have the energy and nutrition required to help fight.
