Primary Outcome Measures:

Improvement in Western Ontario McMaster Osteoarthritis Index (WOMAC) Scores to be taken at Visits 2-5. [ Time Frame: Visit 3 (week 6-7), Visit 5 (week 13-14) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Determine if there is a decrease in amount of non-prescription pain medication taken and/or improvement in score on a timed walking test (Visits 2,3,4,5). [ Time Frame: Visit 3 (week 6-7), Visit 5 (week 13-14) ] [ Designated as safety issue: No ]
Determine if there is a decrease in serum uric acid levels. (Visits 1,3,5) [ Time Frame: Visit 3 (week 6-7), Visit 5 (week 13-14) ] [ Designated as safety issue: No ]

Estimated Enrollment:	50
Study Start Date:	March 2007
Estimated Study Completion Date:	December 2010
Estimated Primary Completion Date:	October 2010 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: 1 proprietary tart cherry juice blend (8 oz., BID)	Other: proprietary cherry juice blend (food) 2 bottles per day for 6 weeks, 1 in the morning and 1 in the evening
Placebo Comparator: 2 control juice (color matched kool aid blend),(8 oz., BID)	Other: control juice (kool aid blend) 2 bottles per day for 6 weeks, 1 in the morning and 1 in the evening

Detailed Description:

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.
