Baker\u2019s cyst volume, MMPRT status, MME, PTS, and Kellgren\u2013Lawrence osteoarthritis grade were assessed using standardized imaging protocols. Factors associated with cyst volume were evaluated using multivariable linear regression. Logistic regression and receiver operating characteristic analysis were performed to assess the relationship between cyst volume and MMPRT. Measurement reliability was evaluated using intraclass correlation coefficients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      MMPRT was independently associated with larger Baker\u2019s cyst volume (p = 0.004). Greater PTS was also associated with increased cyst volume, with each 1\u00b0 increase corresponding to a significant volume increase (p = 0.012). Increasing Kellgren\u2013Lawrence grade remained independently associated with larger cyst volume (p &lt; 0.001), and MME showed an independent but modest association (p = 0.044). The final regression model was significant (F (8,867) = 23.45, p &lt; 0.001) and explained 17.8% of the variance.
