High-intensity walking could lead to a decreased risk of total knee arthroplasty (TKA)&nbsp;for osteoarthritis patients, according to recent research.&nbsp;For the study, researchers compared different intensities of walking and their impact on total knee arthroplasty risk. Data were found using the Osteoarthritis Initiative (OAI) for patients who did not have TKA. An accelerometer recorded step cadence; intensities were defined as follows:&nbsp;&lt;&nbsp;1 step/min&nbsp;was considered&nbsp;non-walking, 1-49 steps/min&nbsp;was&nbsp;very-light, 50-100 steps/min&nbsp;was&nbsp;light, and &gt;&nbsp;100 steps/min&nbsp;was&nbsp;moderate-to-vigorous walking.&nbsp;Researchers measured the impact of replacing not walking time with walking at very-light, light, and moderate-to-vigorous paces over five years.&nbsp;<blockquote class="twitter-tweet" data-width="500" data-dnt="true">
