Name of the Patient : Abc Xyzlmn / M / 42 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Left Knee Joint.

CLINICAL PROFILE :

C/O pain in the left knee joint.
Alleged H/O fall.

EXAMINATION :

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

4 mm thick T1 Weighted, proton and GRASS sagittal images.

4 mm thick T1 Weighted and T2 Weighted coronal images.

5 mm thick GRASS axial images.

OBSERVATION :

There is slight posterior and medial subluxation of the femur over the tibia.

Menisci :

There is seen a vertically oriented hyperintense signal on all the pulse sequences in the posterior horn of the medial meniscus of the left knee joint extending upto both the articular margins. This represents a vertical tear.

The anterior horn of the medial meniscus and posterior horns of the lateral and medial menisci reveal normal configuration and signal characteristics.

Cruciate Ligaments :

The posterior cruciate ligament appears slightly buckled without change in signal intensity.
..2/.





The anterior cruciate ligament is ill-defined and shows a hyperintense signal on the GRASS and STIR images which may suggests a partial tear/strain of the anterior cruciate ligament.

Collateral Ligaments and the Patellar Tendon :

The medial and lateral collateral ligaments and the patellar tendon are normal.

Hoffas Fat Pad :

The Hoffas fat pad is normal.

Articular cartilage and bones :

There is an ill-defined, hyperintense signal on the GRASS and STIR images is the subchondral region along the inferior margin of the lateral femoral condyle, more so laterally. This lesion appears hypointense to normal marrow on the T1 Weighted images. The articular cartilage overlying this region and around the patella and tibia appears normal.

There is a small left knee joint effusion.

IMPRESSION :

1. Slight posterior and medial subluxation of the femur over the tibia.

2. A vertical tear of the posterior horn of the medial meniscus of the left knee joint.

3. Ill-defined anterior cruciate ligament with altered signal along its course may suggests a partial tear/strain.

4. Altered signal in the subchondral region along the inferior margin of the lateral femoral condyle, more so laterally may represent a subchondral fracture/bone bruise in the given clinical setting.

5. A small left knee joint effusion.
