Name of the Patient : Abc Xyzaq Almn / M / 45 yrs.
Examination : M.R.I. of the Left Knee Joint.
CLINICAL PROFILE :
C/O pain in the left knee joint since 6 years.
Alleged H/O vehicular accident with injury to left knee joint.
M.R.I of the left knee joint was performed using the following parameters :
4 mm thick T1 Weighted, proton and GRASS sagittal images.
5 mm thick T1 Weighted and STIR coronal images.
5 mm thick Fast Scan (T2 *) axial images.
There is a complex tear of the anterior horn of the lateral meniscus of the left knee joint.
Linear hyperintense signal on all the pulse sequences in the posterior horns of the medial and lateral menisci not reaching upto the articular margin would represent Grade II meniscal signal (Meniscal degeneration).
The anterior horn of the medial meniscus reveals normal configuration and signal characteristics.
Cruciate Ligaments :
There is an ill-defined, intermediate signal on the T1 Weighted images along the course of the anterior cruciate ligament. This signal appears hyperintense on the proton and T2 Weighted images.
The posterior cruciate ligament is normal contour and signal characteristics.
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 seen a depression fracture of the lateral tibial plateau, more so anteriorly. The underlying bone however shows normal signal intensity. Subchondral pits are noted at the fracture site and in the region of the tibial spine. The articular cartilage is normal. Subchondral erosions are also noted along the articular margin of the patella.
There is a small left knee joint effusion.
1. A complex tear of the anterior horn of the lateral meniscus of the left knee joint.
2. Altered signal along the course of the anterior cruciate ligament would suggest a partial tear/strain of the anterior cruciate ligament.
3. An old depression fracture of the lateral tibial plateau, more so anteriorly with subchondral pits at the fracture site.
4. Subchondral erosions along the articular margin of the patella.
