Detailed Description
The purpose of this study is to determine feasibility of this study design and identify barriers that altered design could bring to overcome these barriers in the design of a large, pragmatic, multi-center clinical trial. It is also designed to estimate the effect size and variance of the main outcome measures, trust and fear, in patients undergoing rehabilitation after total knee arthroplasty (TKA). The study team hypothesizes that intramuscular (IM) oxytocin, in a dose and time determined by a series of previous studies under this grant to target the brain, will enhance trust and reduce fear and that these will be associated with improved outcomes. Again, the study is not designed to test this hypothesis, but to gather the critical data necessary to test it in a large, multi-center clinical trial that would follow this grant.
Participants that have decided to undergo unilateral TKA, will come to the Pain Clinical Research Unit at least 48 hours prior to surgery to confirm consent and complete a series of questionnaires. Participants surgery, anesthesia, and postoperative medication and therapy treatment will be routine. On the first outpatient study visit participants will complete a questionnaire of fear about pain and receive an intramuscular injection of oxytocin or placebo in a randomized, double blind manner. At the end of this session participants will complete a questionnaire assessing the degree of trust in the therapist. Physical therapy be will routine, and the fear and trust questionnaires will be completed at the 2nd, 4th, 8th, and last physical therapy session as well as routine measures of progress and function. The primary outcome measure is assessment of effect size and variability of the trust and fear questionnaires on the 1st and 2nd visit.

Description
Inclusion Criteria:
- Male or female > 18 and < 75 years of age, Body Mass Index (BMI) <40.
- Generally in good health as determined by the Principal Investigator based on prior medical history, American Society of Anesthesiologists physical status 1, 2, or 3. Scheduled for unilateral TKA and postoperative physical therapy at Davie Medical Center.
- Normal blood pressure (systolic 90-140 mmHg; diastolic 50-90 mmHg) resting heart rate 45-100 beats per minute) without medication or for those with hypertension, pressure controlled with anti-hypertensives and with a resting heart rate 45-100 beats per minute.
- Female subjects of child-bearing potential and those < 1 year post-menopausal, must be practicing highly effective methods of birth control such as hormonal methods (e.g., combined oral, implantable, injectable, or transdermal contraceptives), double barrier methods (e.g., condoms, sponge, diaphragm, or vaginal ring plus spermicidal jellies or cream), or total abstinence from heterosexual intercourse for a minimum of 1 full cycle before study drug administration.
Exclusion Criteria:
- Hypersensitivity, allergy, or significant reaction to any ingredient of Pitocin®
- Any disease, diagnosis, or condition (medical or surgical) that, in the opinion of the Principal Investigator, would place the subject at increased risk (active gynecologic disease in which increased tone would be detrimental e.g., uterine fibroids with ongoing bleeding), compromise the subject's compliance with study procedures, or compromise the quality of the data

Physical therapist deems stepping exercise begins; may walk up and down steps
Time Frame: Post-operative 24-48 hours after surgery
|
During routine physical therapy after this surgery, the therapist determines when the patient is ready to begin stepping exercised during therapy.
It is a subjective determination by the therapist.
The outcome measure is the number of days since surgery when the therapist notes in the electronic medical record (EMR) that the patient began stepping exercises.

Gait speed
Time Frame: Post-operative outpatient physical therapy sessions, up to 12 weeks post surgery
|
Gait speed will be measured by the physical therapist at the first physical therapy session and the last physical therapy session and at varying times during physical therapy after surgery using meters/seconds. Distance in meters is divided by the number of seconds. This data will be recorded in the electronic medical recorded and recorded from the electronic medical record. |
Post-operative outpatient physical therapy sessions, up to 12 weeks post surgery
|
Average pain score
Time Frame: Post-operative outpatient physical therapy sessions, up to 12 weeks post surgery
|
