The Claim

In patients undergoing knee arthroplasty, postoperative oral carbohydrate intake is associated with a 0.7-day reduction in hospital length of stay compared to plain water.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Patients who drink carbohydrate solutions after knee replacement surgery stay in the hospital 0.7 days less on average than those who drink only water.

See the scientific wording

In patients undergoing knee arthroplasty, postoperative oral carbohydrate intake is associated with a 0.7-day reduction in hospital length of stay compared to plain water, suggesting a potential impact on resource utilization and recovery efficiency.

Why this might work

After knee surgery, drinking a sugary solution tells the body that energy is available, which stops the stress response, lowers inflammation, and gets the gut moving again. This lets the patient eat normally sooner, feel less hungry and anxious, and leave the hospital half a day earlier.

1 study
  1. Study: Effects of postoperative oral carbohydrate intake immediately on the quality of recovery: a propensity score-matched and multivariate analysis

    After knee surgery, patients who drank a sugary drink right away left the hospital half a day sooner than those who only drank water, according to this study. The sugary drink helped them feel better and recover faster.
