Name of the Patient : Abc Xyz Dlmn / M / 39 yrs.
Referred by : Dr. Abc Xyzesai.
Examination : M.R.I. of the Left Knee Joint.

CLINICAL PROFILE :

C/O pain in the left knee joint with instability of the left knee joint.

EXAMINATION :

M.R.I of the left knee joint was performed using the following parameters :

4 mm thick T1 Weighted and GRASS sagittal images.

4 mm thick T1 Weighted and STIR coronal images.

4 mm thick T1 Weighted axial images.

OBSERVATION :

There is slight forward translation of the left femur over the left tibia.

Slight depression of the lateral tibial plateau is noted.

Menisci

There is a linear hyperintense signal on all the pulse sequences in the posterior horn of the lateral meniscus of the left knee joint reaching upto the inferior articular margin. This represents a Grade III meniscal signal (Meniscal tear).

An intrameniscal signal in the anterior horn of the lateral meniscus and the anterior and posterior horns of the medial meniscus not reaching upto the articular margin suggest meniscal degeneration.


Cruciate Ligaments :

There is an ill-defined, intermediate signal on the T1 Weighted images along the course of the anterior cruciate ligament, which is not seen in continuity. This lesion appears hyperintense on the GRASS and STIR images and suggest a tear of the ACL.

The posterior cruciate ligament shows normal contour and signal characteristics.

Collateral Ligaments and the Patellar Tendon :

The lateral collateral ligament is not well identified in continuity suggesting a ? tear.

The medial collateral ligament and the patellar tendon are normal.

Hoffas Fat Pad :

The Hoffas fat pad is normal.

Articular cartilage and bones :

The articular cartilage overlying the patella, tibia and femur appears normal.

There are ill-defined, hypointense areas on the T1 Weighted images in the head of the fibula, lateral and medial tibial plateau and in the lateral femoral condyle (to a lesser degree in the medial femoral condyle). These areas appear hyperintense on the GRASS and STIR images and most likely represent bone bruise.

Minimal marginal osteophytosis is noted around the left knee joint.

- 3 - Scan-00008



There is a small, left knee joint effusion.

IMPRESSION :

1. Slight forward translation of the left femur over the left tibia.

2. Slight depression of the lateral tibial plateau.

3. Altered signal in the posterior horn of the lateral meniscus of the left knee joint suggests a tear.
4. Altered signal along the course of the anterior cruciate ligament, with discontinuity of the same suggests a tear of the ACL.

5. Suspicious tear of the lateral collateral ligament.

6. Altered signal in the head of the fibula, lateral and medial tibial plateau and in the lateral femoral condyle (to a lesser degree in the medial femoral condyle) suggests bone bruise ? due to previous trauma.

7. A small, left knee joint effusion.
