2. AIMS & OBJECTIVES
 Performing MRI scan in patient’s
presenting with similar complaints – Knee
pain and difficulty in walking.

3. METHODS AND MATERIALS
 Patients were evaluated in last 1 year on 1.5
Tesla MRI scanner – with MRI (plain &
contrast when required) protocol used in knee
joint.

4. LEARNING OBJECTIVE:
 To demonstrate the application of high-
field (1.5T) MRI for the assessment of
knee pathologies.
 To study specific signs on MRI in patents
with and without knee injuries. To
establish the role of MRI in their
management.

5. CASE:1
 History –
H/O pain and effusion in the left knee
joint since 3 days. K/C/O sacro-iliatis. No
H/O trauma or fever or tuberculosis.

6. PD PD T2W
T2W
Suprapatellar and thickened
mediopatellar plicae noted
suggestive of Plica Syndrome.

7. CASE:2
 History –
C/O pain in left knee since few months. H/O frequent small
falls. No H/O of major trauma or fever.

8. Grade III extrusion of anterior horn
and body of medial meniscus on
T1W and T2W image
Mucoid degeneration of lower fibers of
anterior cruciate ligament
Subchondral edema in the anterior
aspect of medial tibial plateau on STIR
image
T1W T2W T2W
STIR

9. CASE:3
 History -
H/O pain in the left knee joint, mainly on the medial
side of knee with increase in pain on climbing the
stairs, since 6 months. No H/O knee injury. Her
anterior drawer test is positive.

10. PD
T2W
T2W
DESS DESS
 Complex meniscal tear in
the posterior horn of
medial meniscus on PD
and T2W.
 Grade II changes
(moderate degree) of
chondromalacia patella
on T2W,and DESS
images.

11. CASE:4
 History –
H/O pain in left knee while walking and
heaviness while walking since last 15
days. Past H/O trauma present before
10 year. O/E: Stress test negative.

12.  Near complete tear of proximal fibers (Femoral
attachment) of anterior cruciate ligament.
 Buckling of posterior cruciate ligament.

13. CASE:5
 History –
H/O pain in right knee while walking
since 2 months. No H/O trauma.

14. Non-ossifying fibroma/ Enchondroma in Diaphysis of the
Femur
PD STIR T1W

15. CASE:6
 History –
19 year old boy with H/O of joint
effusion since 2 months. H/O trauma 2
months back. H/O 3-4 episodes of fever
in last 2 months. ESR is raised.

16. PD STIR T1W

Synovial effusion.
Synovial Thickening
Changes of synovitis
 Favor Possibility of
infective monoarthritis
(Possibly Tuberculous
in origin).

17. CASE:7
 H/O pain in the right knee joint since 15
days. No H/O recent trauma. H/O
trauma 2 years back. H/O on and off
fever. O/E more pain in the anterio-
medial aspect of the knee joint.
History –

18. T1W PD T2W
PD FS T2W
Moderate synovial
effusion
Frond like thickening of
the of the synovium
suggestive of Lipoma
arborescens.

19. MRI “one-stop-shop” method of kneebecame
assessment before arthroscopic surgical
treatment. 1.5T MR-systems allow earliest
diagnosis of knee pathologies(1,2).
