    Biochemical, Functional, and Emotional endpoints


Estimated Enrollment: 60
Study Start Date: October 2010
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: oral Apatone®B
An amalgum of Vitamins C & K3
Drug: Apatone®B
Two capsules taken twice daily with meals
Placebo Comparator: Placebo
Oral capsule of similar appearance and taste without Apatone®B
Drug: Placebo
Two capsules taken twice daily with meals

Detailed Description:

To perform a prospective, randomized, double-blind clinical trial to determine if oral Apatone®B, an amalgam of vitamins C and K3, has a therapeutic efficacy beyond the conservative care customarily used to reduce inflammatory synovitis and to increase the functional capacity of proven non-infected symptomatic postoperative total joint replacements.
