Any disruption of the intra articular structures of the tri-compartmental knee joint or even extra-articular pathologies related to quadriceps mechanism and synovium can cause painful knee resulting in functional morbidity and disability. To ascertain and manage the root cause various modalities are available today. Magnetic Resonating Imaging (MRI) is an effective and non-invasive imaging modality in diagnosing and classifying the knee pathology. With the introduction of special closely coupled extremity coils, high field systems, open systems, extremity units and other technical advances, MRI has virtually replaced conventional arthrography for evaluation of intraarticular pathologies. It has also decreased both morbidity and costs associated with negative intra articular arthroscopic examinations.

The present study was a non-randomized prospective study conducted in Department of Radiodiagnosis and Department of Orthopaedics, Subharti Medical College, Meerut, Uttar Pradesh, India. The study was carried out for a period of three years from September 2015 to September 2018. The study was done on patients presenting in orthopaedics outpatient department, CSS Hospital with knee pain for duration of more than 3 months and subsequent evaluation of the knee joint by using GE SIGNA 1.5 Tesla High gradient MRI Scanner. In each patient T1W, T2W, PD, STIR, GRE and PD-FAT SAT sequences are taken. A total of 100 patients with chronic knee pain i.e. pain for duration of more than 3 months, were studied.

In our study we found that, meniscal tears in young population (age less than 40 years) and meniscal degeneration in patients above 40 years of age is the major finding. Grade 2 medial meniscal tears were most commonly followed by grade 3 medial meniscal tears, followed by lateral meniscal injury. ACL tears were the next most common finding after meniscal injuries or degeneration.

MRI is an accurate, non-invasive and a cost-effective means to evaluate a painful knee. The high degree of precision in interpretation of MR images and imaging in various planes and positioning the knee in 15-20° of external rotation and 5-10° of flexion aided in delineating the site and the full extent of the lesions.
