Abstract
One of the frequent musculoskeletal problems is knee pain. The trend of
increasing of knee pain among the populations is noted. Therefore,
choosing a reliable screening tool with reasonable cost is mandatory.
Although MRI is the gold standard imaging modality for knee soft tissue
structures, it has been widely abused with its high cost. US is an
established modality to image the soft tissuestructures of the knee.
Our aim isto detect the reliability of US in diagnosing cases with knee
pain as compared to MRI.
Our study included twenty patients with knee pain. Every patient
underwent MRI and US examinations independentely and blindly. US is
tested in detecting soft tissue structures pathology such as knee effusion,
meniscal pathology (tear, degeneration and extrusion), medial collateral
ligament, lateral collateral ligament and bursitis (Baker’s cyst) apart
from the cruciate ligaments. It revealed that US showed an overall
sensitivity of 61.7% and specificity of 92.7% with accuracy of 86.9%.
The overall PPV and NPV were 66.1% and 91.3% respectively.
So we can conclude that:
Ultrasound is an effective imaging modality that can be suitable as a
screeningtool for patients having knee pain. Knee US has reasonable
accuracy in detecting collateral ligament and meniscal pathology. US
with the advantages of being widely available, lower in cost and with no
contraindications should bethefirst modality of choice in evaluating knee
pain. MRI can be reserved forequivocal US results.
