Name of the Patient : Abc Xyz Kudtalmn / M / 30 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Left Knee Joint.
CLINICAL PROFILE :
Alleged H/O fall with injury to the left knee joint 4 months back.
C/O pain in the left knee since then.
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 STIR coronal images.
5 mm thick GRASS axial images.
OBSERVATION :
The left knee joint appears slightly hyperextended.
Menisci :
There is a complex, hyperintense signal on all the pulse sequences in the posterior horn of the lateral meniscus of the left knee joint, reaching upto the articular margin. This represents a complex tear.
A hyperintense signal on all the pulse sequences in the posterior horn of the medial meniscus of the left knee joint not reaching upto its articular margin would suggest meniscal degeneration.
The anterior horns of the lateral and medial menisci reveal normal configuration and signal characteristics.
Cruciate Ligaments :
The anterior cruciate ligament is not well identified. In place is noted an ill-marginated intermediate signal intensity lesion on the T1 Weighted images which turns hyperintense on the T2 Weighted images, which would suggest a partial tear of the anterior cruciate ligament.
The posterior cruciate ligament shows normal contour and signal characteristics.
Collateral Ligaments and the Patellar Tendon :
The medial and lateral collateral ligaments are normal.
The patellar tendon appears slightly buckled but shows normal signal intensity.
Hoffas Fat Pad :
The Hoffas fat pad is unremarkable.
Articular cartilage and bones :
Hypointense areas on the T1 Weighted images which turn hyperintense on the T2 Weighted, STIR and GRASS images are seen in the subarticular region of the medial femoral condyle and in the region of the insertion of the posterior cruciate ligament (femoral end). These may represent ? bone contusions.
The lateral margin of the patella extends beyond the lateral margin of the lateral femoral condyle with the knee joint in the extended position.
The articular cartilage overlying the patella, tibia and femur appears normal.
There is a left knee joint effusion.

IMPRESSION :
1. A complex tear of the posterior horn of the lateral meniscus of the left knee joint.
2. Meniscal degeneration in the posterior horn of the medial meniscus of the left knee joint.
3. Ill-defined, altered signal along the course of the anterior cruciate ligament would suggest a partial tear. The fibres of the anterior cruciate ligament are not well identified separately.
4. Slightly hyperextended left knee joint with a laterally subluxated patella (with the knee joint in extension).
5. Small left knee joint effusion.
