Assessment of Alterations in Gait Parameters of Chronic Total Knee Arthroplasty – An Observational Study

Abstract

Purpose of the Study: This research investigates postoperative gait alterations in individuals aged 50 and above who underwent total knee arthroplasty (TKA) at least one year ago. The study aims to fill existing gaps in literature by comprehensively assessing various gait parameters and understanding the persistent changes in mobility following TKA. Materials and Methods: Conducted as an observational study, 30 TKA subjects were assessed using Kinovea software for gait parameters, including cadence, speed, step length, step width, stride length, and knee flexion angle. Statistical analysis with MS Excel compared obtained values with established norms. Results: Significant gait parameter alterations were observed in post-TKA subjects. These changes include decreased cadence, walking speed, step length, and stride length, along with variations in knee flexion angle. Approximately 36.67% of participants exhibited alterations in these parameters, highlighting the need for further understanding of mobility challenges post-TKA. Conclusion: This study contributes vital insights into the persistent impact of TKA on gait parameters, emphasizing the complexity of postoperative mobility changes. The observed alterations highlight the importance of tailored rehabilitation programs to enhance functional independence and address long-term gait concerns in this patient population.
