Objective: to identify the causal and consequential relationship of the relationship with the structural disorders of the meniscus, which has a significant biomechanical effect on the knee joint, with the common osteoartritis process in adults. Method: 94 knee MR examinations of patients consisting of 46 women and 48 men were reviewed retrospectively. In these incidents, medial meniscal location changes-extraints and also the MRI images evaluated and compared the status of MCL, which is one of the main ligaments that supports tibiofemoral cartilage thicknesses, joint distances and medial meniscus, and the findings. Results: A total of 46 women and 48 male patients with an average age of 47.9±12.7 were evaluated by 94 knee MR. As the age average of the cases increased, a significant correlation was found between the medial joint range and the medial meniscus extraction (MME) degree. A positive correlation was found between the medial joint distance and the medial and lateral cartilage thickness and the lateral joint range. As the medial meniscus damage rate increased, the medial cartilage thickness decreased, the MME rate increased. Negative correlation between lateral cartilage thickness and lateral meniscal extraction (LME) degree was also found. According to the MCL damage rates, statistically significant differences between the groups were found in terms of medial extraction (MME) (p<0,001). The result: Meniscal extraction is often seen in the association of increasing degenerative processes with age. The rate of meniscal extraction also increases in neighboring ligaman damage, such as MCL. The need for osteoartritis is meniscopathy and, if necessary, ligaman damage can be seen together while meniscal extraction can be considered the cause of degenerative arthritis development because it facilitates cartilage damage.

The aim of this study was to investigate the relationship between the structural disorders of the meniscus with a significant biomechanical effect in the knee joint with the common osteoartritis process in adult subjects. Methods: Knee MRI images of 94 females and 48 males were retrospectively evaluated in this study. In these cases, medial meniscal displacements-extrusions, as well as the tibiofemoral cartilage thickness and injury of the MCL, one of the basic ligaments supporting the knee medially, joint distances and meniscus injury were investigated, and the findings were compared. Results: A total of 94 knee MRIs of 46 female and 48 male patients with an average age of 47.9 ± 12.7 were evaluated. There was a significant correlation between medial joint space and medial meniscus extrusion (MME) degree as the average age of the patients increased. There was a positive correlation between medial joint distance and medial and lateral cartilage thicknesses and lateral joint space. As the medial meniscus damage degree increased, the medial cartilage thickness decreased and the MME degree was increased. In addition, there was a negative correlation between lateral cartilage thickness and lateral meniscal extrusion (LME) degree. There was a statistically significant difference between the groups with MME and MCL injury (p <0,001). Conclusion: Meniscal extrusion is a common finding with degenerative processes that increase with age. The meniscal extrusion ratio is also increased in adjacent ligament damage such as MCL. Although both OA and meniscopathy and ligament damage can be seen together, meniscal extrusion can be considered as a cause of degenerative arthritis because it facilitates cartilage damage.
