Background: Knee replacement enables the surgical management of end-stage knee joint osteoarthritis. 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. Methods: 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. Results: Out of 420 patients, 350 were females (83.33%) and 70 males (16.67%). The mean age was 69.50 ± 7.48 years (range, 48–90). 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 ± 9.65; SD, 36.89 ± 8.23) but improved postoperatively (mean, 81.42 ± 12.74; SD, 85.49 ± 11.69; P < 0.001). The timed up and go test significantly changed from 28.51 ± 3.29 s to 18.18 ± 3.17 s (P < 0.001) and 2-min. walk test from 51.83 ± 6.48 m to 85.72 ± 8.92 m (P < 0.001). Conclusion: Despite knee replacement's late acceptance in Saudi Arabia, there have been increased cases in recent years and excellent improvements in knee function. The resulting knee society functional and knee scores, timed up and go tests, and 2-min. walk tests were better or similar to results seen by other researchers worldwide.
