In Saudi Arabia, there has been a recent increase in total joint replacement surgery. However, there is insufficient literature regarding patient outcomes in this region. Here, we assessed characteristics of patients who underwent total knee arthroplasty and their improvements on knee society score, timed up and go test, and 2-min. walk test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Patients who underwent primary total knee replacement at our tertiary care private hospital in Abha from January 2013 to January 2020 were included. The same orthopedic surgery performed primary cemented cruciate-substituting knee replacement. Knee function was evaluated using the knee society scoring system, timed up and go test, and 2-min. walk test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Out of 420 patients, 350 were females (83.33%) and 70 males (16.67%). The mean age was 69.50 \u00b1 7.48 years (range, 48\u201390). Most patients had osteoarthritis (84.5%), either degenerative or secondary because of trauma. Knee society functional and knee scores were poor preoperatively (mean, 38.21 \u00b1 9.65; SD, 36.89 \u00b1 8.23) but improved postoperatively (mean, 81.42 \u00b1 12.74; SD, 85.49 \u00b1 11.69;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001).
