The Claim
In patients undergoing knee arthroplasty, immediate postoperative oral carbohydrate supplementation is associated with a 4-point higher Quality of Recovery-15 score at 24 hours compared to plain water.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Patients who drink a carbohydrate solution right after knee surgery have a 4-point higher recovery score at 24 hours than those who drink plain water.
See the scientific wording
In patients undergoing knee arthroplasty, immediate postoperative oral carbohydrate supplementation is associated with a 4-point higher Quality of Recovery-15 score at 24 hours compared to plain water, suggesting improved overall recovery quality, likely due to better metabolic and psychological stabilization during the early postoperative catabolic phase.
After surgery, the body enters a stressed state that raises blood sugar and stress hormones, making patients feel hungry, anxious, and slow to recover. Drinking a sugary solution right after surgery tells the body that energy is available, which lowers stress hormones, helps insulin move sugar into muscles, calms the gut, and reduces hunger and anxiety. This lets the body shift from breaking down tissue to healing, leading to faster and smoother recovery.
What the research says
1 studyAfter knee surgery, patients who got a sugary drink right away felt better the next day than those who got plain water, and the study proves it—those patients scored higher on a recovery scale and felt less hungry and anxious too.
