After being informed about the study and potential risks, all patients giving written informed consent will be screened to determine eligibility for study entry. Patients who meet eligibility criteria will be randomized into one of two groups: Standard of Care or the POPOP (20Lighter).
In this pilot study, we will test the hypothesis that a POPOP for currently ineligible UAMS orthopedic surgery patients wanting hip or knee replacement improves markers of preoperative health, ability to reach a BMI threshold <40 kg/m2 required for surgical eligibility, and postoperative outcomes versus SOC.
