Date of Service: 1/28/2011
Exam: (STO) LT MRI KNEE WITHOUT CONTRAST

INDICATION
History of arthroscopic surgery and staph infection of the left knee, evaluate for absence of cartilage.

COMPARISON
None.

TECHNIQUE
The examination was performed on an ONI extremity scanner. Five data acquisition series were obtained: one in the coronal plane with T1 weighting, a second in the coronal plane with a STIR technique, a third in the axial plane with T2 weighting, a fourth in the sagittal plane with a proton density technique, and the last in the sagittal plane with a T2-weighted technique.

FINDINGS

LIGAMENTS AND TENDONS
The medial and lateral collateral ligaments are normal. The biceps femoris tendon, popliteus tendon and iliotibial band are all normal. There is a chronic grade-3 tear of the anterior cruciate ligament with few remaining fibers visualized. The posterior cruciate ligament is normal. The patellar and quadriceps tendons are normal.

MENISCI
There is markedly abnormal morphology and degeneration of the medial and lateral menisci, which represents complex degenerative tears and possibly prior partial meniscectomies. No prior studies are available for comparison.

BONES AND CARTILAGE
There is tricompartmental osteoarthritis with marginal osteophyte formation and diffuse joint space narrowing. There is complete loss of articular cartilage within all three knee joint compartments with underlying subchondral bone marrow edema, eburnation and cystic change. There is a mild contour deformity of the inferior patellar facet. Note is also made of medial and lateral intercondylar wall osteophytes which measure 6 mm in size and encroach upon the normal course of the cruciate ligaments.

SOFT TISSUES
There is a physiologic knee joint fluid present. There is no Baker's cyst or other abnormal bursal fluid collection. There is extensive scarring within Hoffa's fat pad from prior surgery.

IMPRESSION
1. Chronic complete tear of the anterior cruciate ligament.

2. Complex, degenerative tears of the both the medial and lateral menisci +/- prior partial meniscectomy.

3. Tricompartmental osteoarthritis with marginal and intercondylar wall osteophyte formation. The intercondylar wall osteophytes encroach upon the expected position of the cruciate ligaments.

4. Tricompartmental extensive full-thickness articular cartilage loss with underlying subchondral bone marrow edema, eburnation and cystic change.

5. Extensive scarring in Hoffa's fat pad, indicative of prior surgery.
