Name of the Patient : Abc Xyzn S. Aylmn / F / 49 yrs.
Referred by : Dr. Abc Xyzni.
Examination : M.R.I. of the Right Knee Joint.
CLINICAL PROFILE :
C/O pain with swelling over the right knee joint, limitation of joint movements, clicking and locking of the right knee joint.
H/O fall many years ago with injury to the right knee.
M.R.I of the right 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.
4 mm thick Fast Scan (T2 *) axial images.
There is a horizontal hyperintense signal on all the pulse sequences in the posterior horn of the medial meniscus not reaching upto the articular surface and represents Grade II meniscal signal (meniscal degeneration). The posterior horn of the lateral meniscus is surrounded by fluid.
The anterior horns of the lateral and medial menisci reveal normal configuration and signal characteristics.
Cruciate Ligaments :
The anterior and posterior cruciate ligaments show normal contour and signal characteristics.
- 2 - Scan-00005
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 are small subchondral erosions along the articular surface of the lateral femoral condyle and the lateral tibial plateau which are hypointense to the normal marrow on the T1 Weighted images and turn hyperintense on the T2 Weighted images. Tibial and femoral osteophytes are noted.
There is reduction in the medial and lateral tibio-femoral compartments of the right knee joint.
Fluid is seen within the right knee joint and the suprapatellar bursa.
Marrow inhomogeneity is seen in the lower shaft of the right femur.
The articular cartilage overlying the patella appears normal. The articular cartilage overlying the lateral femoral condyle and the lateral tibial plateau appears thin.
Incidental note is made of dilated tortuous veins in the subcutaneous fat in the popliteal fossa suggestive of varicose veins.
The MRI features are suggestive of :
1. Altered signal in the posterior horn of the medial meniscus not reaching upto the articular surface represents Grade II meniscal signal (meniscal degeneration).
- 3 - Scan-00005
2. Osteoarthritic changes in the right knee joint with subchondral erosions adjacent to the lateral tibio-femoral joint, thinning of the articular cartilage and marginal osteophytes.
3. Right knee joint effusion.
