Abstract Background: Osteoarthritis (OA) is a chronic degenerative joint disorder characterized by progressive cartilage deterioration, synovial inflammation, and remodeling of subchondral bone. Methodology: A total of 150 patient records were initially screened for eligibility. Based on the inclusion criteria, patients above 40 years, diagnosed with primary knee OA, and who had complete documentation regarding their preoperative body mass index (BMI) and postoperative functional recovery metrics, 120 records were retained for final analysis. Functional outcome was measured using the Oxford Knee Score (OKS), a validated 12-item questionnaire assessing pain and knee functionality from the patient’s perspective. Postoperative complications were classified into categories, including wound-related issues, infections, prosthetic instability, thromboembolic events, and readmissions. Results: Majority of the participants reported suffering from chronic diseases (61.7%), and 44.2% had a right-sided condition, followed by 29.2% with left-sided involvement and 26.7% with bilateral symptoms. Notably, 20.8% of the participants experienced postsurgical complications, and a very high proportion (95.8%) had completed their postsurgical rehabilitation. There was a strong positive correlation between BMI and OKS, rs = 0.740, P < 0.001, indicating that participants with higher BMI tended to report higher knee outcome scores. A significant negative correlation was observed between age group and OKS, rs = −0.203, P = 0.026, indicating that higher age was associated with lower OKS scores. Conclusion: Study findings match the recent findings, which consistently report lower functional scores, higher complication rates, and increased revision risks in obese populations. The results advise for comprehensive prehabilitation strategies and multidisciplinary care pathways to high-risk groups.
