| dcterms.abstract | Three-dimensional biomechanical gait analysis is an assessment tool that provides insight into patient functioning following a total knee arthroplasty (TKA) or a unicompartmental knee arthroplasty (UKA). Knee flexion moment is a biomechanical variable that provides insight into an individuals’ willingness to load the knee joint. One challenge of the data collection process with these patients suffering from osteoarthritis is function, especially pre-operatively, is limited due to pain and fatigue which can restrict the researcher’s ability to capture the required information. Additionally, how do both operative groups recover in terms of stair negotiation ability? Stairs are known to be a more challenging task that occurs with aging, and is even more challenging in osteoarthritis suffers. The degree to which an individual is able to perform the stair negotiation task in the absence of pathology remains in question. Results of this dissertation provide recommendations of the biomechanical data collection process. In patients that present with lower extremity joint pain and/or fatigue, identifying the force plate during the data collection process has limited clinical outcomes on biomechanical variables and will limit the number of redundant trials. Through using stair negotiation as an assessment tool, short-term (three months following surgery) functional ability favors those patients undergoing UKA. These UKA patients have knee flexion moments that are more similar to healthy controls. Furthermore, functional deficits in knee flexion moment remain in TKA patients out to one-year post-operatively when compared to healthy age-matched controls. Results of this dissertation also suggests that the long-term difficulty of the stair task in TKA patients is more related to the osteoarthritis pathology than the aging process as evident by the ability of all of the healthy controls participants to negotiate the stairs with ease. | |
