Objective:

To examine the relationship between alterations in soft tissue and the intensity of knee osteoarthritis (OA), emphasizing gender disparities.

Approach:

Key Findings:

• 54.7% of participants were female and 45.3% male, with a majority aged 30–44 years and classified as obese (44.8%).
• Muscle thickness remained stable across BMI categories; males had higher measurements than females.
• Fat thickness increased with BMI; females had greater measurements than males.
• The muscle-to-fat ratio decreased as BMI rose, with males having a higher ratio in the normal BMI category.
• Weak negative correlation found between muscle-to-fat ratio and soft tissue degenerative changes and cartilage degenerative changes.

Interpretation:

The muscle-to-fat ratio and fat thickness significantly influence degenerative changes in the knee, particularly in females.

Limitations:

• Study limited to individuals who received both X-ray and MRI examinations.
• Exclusion of patients with prior knee surgeries or significant injuries may limit generalizability.

Conclusion:

The integration of MRI and X-ray enhances diagnostic precision for knee osteoarthritis.
