BACKGROUND: Meniscal injuries pose a significant orthopedic challenge, demanding a thorough understanding of demographic and injury-related factors for successful treatment. The importance of age, body mass index (BMI), time from trauma to surgery, injury causes, patient occupation, and the presence of anterior cruciate ligament (ACL) injury in influencing postoperative outcomes prompted this prospective cross-sectional clinical study. METHODS: Conducted from November 2022 to July 2023 with 30 patients, this study utilized rigorous methodologies, employing both analysis of variance and Spearman's correlation analyses. The aim was to comprehensively assess the relationships among these factors and postoperative results in meniscal surgery patients. RESULTS: The study found that early surgical intervention significantly improved outcomes for meniscal injuries, with patients operated on within two months achieving 100% excellent and good results, compared to 50% for those treated after six months. Younger age, lower BMI, and sports-related injuries were associated with better postoperative Lysholm scores, while higher BMI and delayed surgery correlated with poorer outcomes. Patients with concurrent ACL injuries had a 95.4% rate of excellent and good results, compared to 50% for those with intact ACLs. CONCLUSION: This study underscores the pivotal role of age, BMI, and ACL injury considerations in shaping effective treatment strategies for meniscal injuries. The nuanced insights gained from the analysis emphasize the critical importance of early surgical intervention, particularly in cases involving ACL injuries, to optimize postoperative outcomes.
