Introduction: Osteoarthritis (OA) is a clinical condition affecting over 27 million Americans. There is no known cure for OA other than replacing the diseased joint with a joint prosthesis, total knee arthroplasty (TKA). Purpose: This study compared pre and post-surgical functional ability, exercise self efficacy and outcome expectations among total knee arthroplasty (TKA) patients who did and did not receive a prehabilitation exercise program. Methods: 67 participants were eligible to participate in the study. Twenty-five participants indicated that they were not interested in participating in the study. As a result forty-two OA participants (31 female, 11 male) of the 42, 37 were interested and recruited into the study (n = 19 PRE, n = 18 CON). The analytic sample (n = 16 PRE, n= 15 CON) included 31 subjects (22 female, 9 male). Outcome Variables: self-efficacy to exercise survey (SEE), outcome expectations to exercise survey (OEE), 6-minute walk distance, number of sit-to-stand repetitions in 30 seconds, the timed get up and go (TUG) test. Results: The effect of time was non-significant for SEE,p = .655 and OEE,p = .146. There was no significant interaction effect on SEE,p = .590 or OEE,p = .933. There was a significant effect of time on the six minute walk,p <.001, TUG,p < .001; sit-to-stand, p < .001, ascending stair, p < .001 and on descending stair, p = .001. Presentation: The dissertation is divided into five chapters, covering the clinical conditions of OA, treatment, impact of the problem, and the benefits of exercise. Chapter One gives an overview of the problem, impact of the problem, its history and discusses the significant health problem as a result of OA. Chapter two uses a review of the current literature to examine the conceptual framework and theory used in this study along with the introduction of the prehabilitation exercise intervention. Chapter three discusses the methodology used in the study and chapter four gives the data analysis and reports the findings of the data collected during the study. Finally chapter five gives a brief introduction of the study followed by the conclusions of the study. These conclusions include interpretations of the findings, discussions of the research hypotheses, recommendations, future research, theory application and finally future studies, limitations and a brief summary of the study.
