Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary purpose of this research study is to test the ability of a proprietary cherry juice blend to be helpful in the treatment of osteoarthritis (OA) of the knee.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The primary objective is to determine if the proprietary tart cherry juice blend improves the pain and function in persons with knee osteoarthritis. A secondary objective is to ascertain if the blend lowers serum uric acid.

This is a prospective double blind, placebo controlled cross-over study.

The study will be performed in the Philadelphia VA Medical Center 1 South Rheumatology Clinic with patients meeting ACR criteria for Kellgren grade 2-3 knee osteoarthritis and 4-9 pain severity on a VAS. Fifty patients will be studied with each having 5 visits. Subjects will take either the proprietary cherry blend or placebo for 6 weeks and then switch. WOMAC pain and function will be the primary outcome with acetaminophen use, walking time and serum uric acid as secondary outcomes.
