A cross-sectional study involving 113 patients (mean age of 44.94 ± 6.69 years) with knee pain revealed a 19.47% frequency of Baker’s cyst on magnetic resonance imaging (MRI), indicating a significant prevalence in this population. The primary objective was to establish the prevalence of Baker’s cyst in patients battling knee pain, utilizing MRI as the imaging modality. A comprehensive sample of 113 patients (age range of 15 to 65 years) was chosen, out of which 65 (57.52%) were male, and 48 (42.48%) were female, yielding a male-to-female ratio of 1.4:1.

All participants experienced knee pain lasting more than 4 weeks and were referred for knee MRI evaluation. Exclusions were made for post-surgical cases and individuals having contraindications for MRI. The diagnosis was performed utilizing a 1.5 Tesla scanner, positioning the knee in extension with slight external rotation. The interpretation of magnetic resonance images for the identification of Baker's cyst presence or absence was carried out by a consultant radiologist.

The patients exhibited a mean body mass index (BMI) of 27.45 ± 3.02 kg/m2, and the average duration of pain was 5.78 ± 2.30 months. The MRI analysis identified Baker’s cyst in 22 patients with knee pain, indicating a frequency of 19.47%. The findings underscored a considerable occurrence of Baker's cyst on MRI of individuals experiencing knee pain. Hence, regular use of MRI for those experiencing knee pain is suggested to diagnose issues at an early stage. This proactive approach can help halt disease advancement and subsequently minimize the risk of associated complications.
