Comparative Analysis of Knee Replacement Surgery who follow up by Physical Therapy and Intra-articular Steroid Injections for Obese Patients.

Knee osteoarthritis (KOA) is the most common chronic articular disease, and its prevalence has doubled since the mid-20th century. It affects 16% of the adult population over 50 years of age in the post-industrial era [1]. Obesity is one of the only modifiable risk factors for both incidence and progression of Osteoarthritis (OA).[2] Although OA was previously regarded as a disease of the elderly, its development starts much earlier than originally thought, and OA is ranked among the top 20 diseases in the 40–45 years age group [3]. This review aims to provide a comprehensive analysis of the outcomes of knee replacement surgery following up physical therapy, versus intra-articular steroid injections for obese patients (BMI >30) The study design employed in this review is narrative, and articles published after 2010 from PubMed were considered for inclusion. The review examines the impact of each intervention on the complete regain of knee function in this specific population. Through the analysis of relevant studies, this review seeks to inform clinical decision-making and guide the management of obese patients with knee osteoarthritis. Conclusion.  Based on the reviewed literature, knee replacement surgery appears to offer a better chance of achieving complete regain of knee function in obese patients (BMI >30) undergoing physical therapy compared to intra-articular steroid injections. However, the findings are limited by the availability of studies and the heterogeneity in the research methodologies.
