Introduction This research, set in 2023 in Saudi Arabia, addresses the rising prevalence of knee osteoarthritis (OA) among obese individuals. It explores associations with age, BMI, and gender, aiming to enhance our understanding of this pressing health issue within the Saudi context and contribute to global research on OA and obesity. Methodology A retrospective cohort study was conducted at King Saud Hospital and Buraydah Central Hospital in the Al-Qassim region from November 2022 to February 2023. It included the patients' records that fit the inclusion criteria during the study period. A data collection sheet was used to collect data, and data was analyzed using SPSS Statistics version 27.0.1 (IBM Corp. Released 2020. IBM SPSS Statistics for Windows, Version 27.0. Armonk, NY: IBM Corp.). Results In 2023, a study on knee OA among 267 obese individuals in Saudi Arabia yielded significant findings. The median age of participants was 60 years, with an average weight of 77.00 kg (IQR:15) and a median BMI of 29.14, categorizing participants as overweight. Ninety percent (n=240) of knee OA cases occurred in individuals classified as "obese" (n=118) or "overweight (n=122)". Furthermore, OA primarily affected both knees in 79.4% (n=212) of cases. Conclusion Study participants, predominantly older and female, reflect OA's age-related and gender-specific prevalence trends. Notably, excess weight and a higher BMI highlight the role of obesity as a significant OA risk factor. Bilateral knee involvement is common, with a strong link between OA and obesity.
