Objectives: The use of Magnetic Resonance Imaging (MRI) as a diagnostic tool for musculoskeletal disorders has gained popularity among Orthopaedic surgeons over the years. It is believed to be an accurate, non- invasive diagnostic tool for investigations of the athletic knee, some lesions remain undetected with MRI scan and this discrepancy may be dependent on the interpretation of the radiologist. In this instance, arthroscopy will be the last arbiter. Arthroscopy is the "gold standard" for diagnosis of both traumatic and degenerative knee lesions.

Methods: Patients with knee pathologies that presented to the Arthroscopy and Sports Medicine Unit of the hospital between 2013 and 2017 were recruited into this study. Data was extracted from the case notes into the proforma and analysis of the required data for correlation of the MRI findings with the Arthroscopic Findings.

Results: 46 patients were studied, there were 35 males (76.1%) and 11 females (23.9%). Age Range was 14-68 years. Right knee was more involved - 29 patients (63%) and the left knee in 17 patients (37%). The youngest patient had osteochondral defect of the medical femoral condyle while the oldest patient had lateral meniscal injury.
Sporting activities were the most common mechanism of injury involving 18 patients (39.13%).
The imaging studies provided a diagnostic accuracy of 80.43% for Medial Meniscus, 60 % for |Lateral Meniscus, 89.13% for Anterior Cruciate Ligament (ACL), 93.48% for posterior cruciate Ligament and 100% for Osteochondritis Dissecans (OCD).

Conclusions: The Magnetic Resonance Imaging still remains a mainstay in the diagnosis of pathological lesions of the traumatic or degenerative knee and also an invaluable adjunct in the arthroscopic management of orthopaedic pathology of the knee.
