Abstract

As the population of individuals undergoing total hip arthroplasty (THA) continues to grow, it becomes increasingly important to understand the progression of recovery from both functional and movement perspectives. Current research investigating movement symmetry following THA has focused on discrete 6 events such as peak angles, thereby disposing of the majority of data collected in a gait analysis. Therefore, the purpose of the current study was to utilize a vector coding technique to assess movement symmetry in the hip and knee joint angles and moments before and for multiple time-points up to 1 year after surgery. We observed that control participants consistently spent a significantly greater percentage of stance moving and loading the knee and hip joints symmetrically than the THA participants did at all time-points. THA participants exhibited a greater percentage of stance moving and loading the contralateral side, showing a continuing reliance and stress on contralateral joints. Though many measures did not change over time, the progression of the sagittal plan knee motion and moment in the contralateral joint suggest that risk may be increasing after the 1 year that these data were collected. Therefore, it is important that future work investigate THA patients for longer than 1 year after surgery and that rehabilitation programs emphasize health in both lower extremity limbs, not just the surgical side.
