The association between Baker's cyst and medial meniscal tear in patients with symptomatic knee using ultrasonography

There are nearly no studies about the association between Baker's cyst (BC) and medial meniscal tear (MMT) using ultrasonography.

Nonselected patients who were referred for ultrasonography for the evaluation of knee pain were recruited. Demographic, clinical, and ultrasound parameters were documented.

One-hundred and nineteen patients were included and 131 knees were evaluated. There were 59 (~50%) female patients and mean age of 46.4±17.7 years. BC was found in 31 knees (23%). BC was significantly associated with MMT (P=.029) and age (P=.002) after adjusting for other covariates.

BC was strongly associated with MMT regardless of other intraarticular abnormalities.
