Name of the Patient : Abc Xyzkar Ghotlmn / M / 65 yrs.
Referred by : Dr. Abc Xyzra.
Examination : M.R.I. of the Right Knee Joint.
CLINICAL PROFILE :
C/O pain in the right knee joint (upto hip) with swelling and limitation of knee joint movements since 4 months.
H/O osteoarthritis of the left knee joint and osteotomy done in 0000.
M.R.I of the right 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.
4 mm thick GRASS axial images.
There is a complex tear of the posterior horn of the medial meniscus.
The anterior and posterior horns of the lateral meniscus and anterior horn of the medial meniscus reveal a linear hyperintense signal on all the pulse sequences. This does not extend upto the articular surface and would represent Grade II meniscal signal (degeneration).
Cruciate Ligaments :
The anterior cruciate ligament is not well identified. Areas of intermediate signal intensity on the T1 Weighted images which turn hyperintense on the Fast Scan (T2 *) images are seen along its course and this may suggest a tear of the anterior cruciate ligament.
- 2 - scan-00005
The posterior cruciate ligament shows 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 unremarkable.
Articular cartilage and bones :
The articular cartilage overlying the patella is thin and irregular.
A hypointense area on the T1 Weighted images which turns hyperintense on the GRASS images is seen within the subchondral aspect of the lateral patellar facet and may represent cystic degenerative changes.
Subchondral cysts are noted within the medial femoral condyle.
Effusion is seen within the right knee joint.
There are degenerative changes within the knee joint with osteophytic lipping of the patella, tibia and femur.
The MRI features are suggestive of degenerative changes within the right knee joint with :
1. A tear of the anterior cruciate ligament of the right knee joint.
2. A complex tear of the posterior horn of the medial meniscus of the right knee joint.
3. Chondromalacia patellae.
4. Fluid within the right knee joint.
