Name of the Patient : Abc XyzGlmn / M / 30 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 limitation of joint movement and clicking since 0000.
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.
The anterior and posterior horns of the lateral and medial menisci reveal normal configuration and signal characteristics.
Cruciate Ligaments :
There is an ill-defined, hyperintense signal on the GRASS and STIR images along the fibres of the anterior cruciate ligament. This is of intermediate signal on the T1 Weighted images. The fibres of the anterior cruciate ligament appear to be in continuity.
The posterior cruciate ligament shows normal contour and signal characteristics.
Collateral Ligaments and the Patellar Tendon :
There is an intermediate signal on the T1 Weighted images within the substance of the patellar tendon, just inferior to the inferior margin of the patella. This lesion appears hyperintense on the GRASS and STIR images and would most likely represent an intrasubstance degeneration/tendinitis of the patellar tendon. The patellar tendon is slightly larger in diameter in this region. The central portion of the tendon appears more involved.
The medial and lateral collateral ligaments are normal.
Hoffas Fat Pad :
The Hoffas fat pad appears slightly ill-defined along the postero-inferior margin of the inferior pole of the patella ? due to inflammation.
Articular cartilage and bones :
The articular cartilage overlying the patella, tibia and femur appears normal.
The trabeculae of the distal end of the left femur and proximal end of the left tibia appear prominent without change in the marrow signal, suggesting remodelling of bone.
A herniation pit is noted in the region of the tibial spine.
1. Slight increase in diameter of the patellar tendon with altered signal within the substance of the patellar tendon, just inferior to the inferior margin of the patella as described represents chronic patellar tendinitis.
2. Altered signal along the fibres of the anterior cruciate ligament would suggests a strain of the anterior cruciate ligament.
