PROCRIT and Short-Term Outcomes in Orthopedic Surgery

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to compare the effect of perioperative administration of PROCRIT to that of autologous blood donation on post-operative rehabilitation outcomes in patients undergoing unilateral knee surgery.

Detailed Description
-----------------
The primary objective of this study is to compare the effect of perioperative administration of PROCRIT to that of preoperative autologous donation on post-operative rehabilitation outcomes in subjects undergoing primary unilateral knee arthroplasty. Secondary objectives are : 1) To compare the effect of perioperative administration of PROCRIT to that of preoperative autologous donation on hemoglobin, change in hemoglobin, number of units transfused and transfusion rate during the study period; and 2) To compare the effect of perioperative administration of PROCRIT to that of preoperative autologous donation on inpatient rehabilitation length of stay. The study will test the hypothesis that perioperative administration of PROCRIT will improve post-operative rehabilitation outcomes, compared with preoperative autologous donation. 40,000U PROCRIT or Placebo SC in relation to surgery date: Days -21, -14, -7, 0 (day of surgery), 7, and 14.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The primary endpoint is the change in composite FIM scores (from entry into the inpatient rehabilitation facility to discharge from inpatient rehabilitation) divided by the LOS, denoted as DFIM/LOS, or rate of functional recovery. |  |  | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| LOS in the inpatient rehabilitation facility; Total FIM score; FIM Physical Sub-score LASA score; FACIT-An score. Safety evaluations include the incidence of adverse events throughout the study |  |  |
