Brief Summary:
The purpose of this study is to determine if continuing fish oil supplementation leads to higher blood loss in patients undergoing total hip arthroplasty (THA). Another purpose is to determine if patients on fish oil have less pain after THA. Fish oil (Omega-3 fatty acid) is commonly used by patients as a natural anti-inflammatory to decrease joint pain from arthritis. Supplements, including fish oil, are typically stopped 1-2 weeks prior to surgery as there is an increased risk of perioperative bleeding. However, there are current methods in joint replacement surgery that decrease the risk of perioperative bleeding. With the risk of excessive bleeding being minimized, fish oil may not need to be stopped prior to surgery and could be continued immediately after surgery. The anti-inflammatory effect of fish oil may also help decrease pain after surgery.

Arm Intervention/treatment
Experimental: Fish Oil
Fish-Oil naïve subjects will be started on fish oil 4 weeks prior to surgery and continued until the 6 week follow up. Subjects already taking fish oil will be switched to the study fish-oil formulation of two capsules twice daily (3000 mg of EPA and DHA).
 Dietary Supplement: Fish Oil
Fish-oil formulation of two capsules twice daily (3000 mg of EPA and DHA).
No Intervention: Control
No fish oil supplementation


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Total perioperative blood loss [ Time Frame: Post-operative day 5 ]
    Calculated total perioperative blood loss (mL) using Bourke's, Gross', Camarasa's, and Lopez-Picado's formula based on Post Operative Day 5 (POD5) Hemoglobin and Hematocrit


Secondary Outcome Measures :
  1. Post-operative day 1 Hemoglobin [ Time Frame: Post-operative day 1 ]
    Post-operative day 1 Hemoglobin

  2. Post-operative day 1 Hematocrit [ Time Frame: Post-operative day 1 ]
    Post-operative day 1 Hematocrit


Other Outcome Measures:
  1. Post-operative pain scores [ Time Frame: Post-operative day 1 pain scores will be determined for each patient using the visual analog scale ]
    Post-operative pain scores will be determined for each patient using a numeric rating scales (NRS) with 0 being no pain and 10 being worst pain possible.
