Name of the Patient : Abc Xyz Achlmn / M / 32 yrs.
Referred by : Dr. Abc Xyzni.
Examination : M.R.I. of the Right Knee Joint.
CLINICAL PROFILE :
H/O fall 2 weeks back with pain and swelling over the right knee joint since then.
H/O arthroscopy done in 0000 on the right knee joint (details not available).
EXAMINATION :
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.
OBSERVATION :
Menisci :
The posterior horn of the medial meniscus of the right knee joint appears blunted and shows a diffuse hyperintense signal on the proton and T2 Weighted images. These changes may be the sequelae of previous menisectomy or may suggest a complex tear. The subchondral bone in the medial femoral condyle adjacent to the posterior horn of the medial meniscus shows an ill-defined, hyperintense signal on the GRASS and STIR images which is hypointense on the T1 Weighted images and may represent subchondral degeneration/bone bruise. Slight thinning of the articular cartilage overlying the medial femoral condyle is also noted (scans 102.6 and 103.6).
Scan-00007
The anterior horn of the medial meniscus is also not well identified. The anterior and posterior horns of the lateral meniscus reveal normal configuration and signal characteristics.
Cruciate Ligaments :
The anterior cruciate ligament is not visualized along its normal course and there is a chronic tear of the anterior cruciate ligament in all probability.
The posterior cruciate ligament is buckled. Slight retroplacement of the right femur in relation to right tibia is noted.
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 a depression along the infero-lateral margin of the lateral femoral condyle in its subchondral region, which appears hypointense on the T1 Weighted images and hyperintense on the STIR and GRASS images. The articular cartilage overlying this region is puckered. The lateral tibial plateau also shows a diffuse hyperintense signal on the STIR and GRASS images.
There is a small right knee joint effusion.

IMPRESSION :
1. Blunting of the posterior horn of the medial meniscus of the right knee joint with altered signal may either be the sequelae of previous menisectomy or may suggest a complex tear.
2. Chronic tear of the anterior cruciate ligament.
3. Altered signal in the subchondral region of the medial femoral condyle may either represent subchondral degeneration or may represent bone bruise in the given clinical setting.
4. Depression along the infero-lateral margin of the lateral femoral condyle with puckering of the overlying articular cartilage may represent a subchondral fracture in the given clinical setting. Altered signal in the lateral femoral condyle would represent a bone bruise.
5. A small right knee joint effusion.
