MRI - RIGHT KNEE WITHOUT CONTRAST
MRI of right knee was done on 1.5 Tesla using extremity coil. PD, T2W, GRE and T2W fat-sat sagittal imaging was done. T1W coronal and T2W
fat-sat coronal and axial imaging was also done.(CD containing MRI images given along with the films).
There is non-visualisation of ACL, likely represent chronic complete tear. Buckling of
PCL is noted with anterior translation of tibia with respect to femur.
Mild ill-defined intrasubstance increased signal intensity is seen in proximal fibers of
PCL near femoral attachment, may represent early myxoid degeneration changes.
Edematous / fluid signal are seen on both sides of MCL, suggest grade I injury (sprain).
LCL is intact. Mild edematous signals are seen in relation to it, may represent low grade
Altered morphology with increased signal intensity is seen involving body ad posterior
horn of medial meniscus, suggesting tear.
Increased signal intensity is seen in body - posterior horn of lateral meniscus reaching
upto inferior articular surface, suggesting tear.
Mild to moderate joint effusion is seen with fluid in posterior recess.
An area of partial to full thickness cartilage erosion, measuring ~ 17 x 8mm is seen at
medial femoral condyle. Mild underlying subchondral sclerosis is seen. Subchondral marrow
edema is seen at medial femoral and tibial condyles, probably post traumatic. D/Dx:-
degenerative. Small focus of cartilage thinning is seen at medial facet of patella. Tiny focus of
subchondral marrow edema is seen at lateral trochlear surface of femur, suggesting
degeneration changes in overlying articular cartilage. No definite cartilage erosion is seen at
lateral tibiofemoral compartment. Small osteophyte are seen at medial tibiofemoral
Trochlear groove is shallow in its cranial part, suggesting element of trochlear dysplasia.
Otherwise visualised bones reveal normal marrow signal intensity.
Patellar and quadriceps tendons are unremarkable.
There is thinning of medial patellar retinaculum with edematous signal in its posterior
aspect. Mild edematous signals are seen between adductor magnus tendon and vastus
medialis obliquus muscle.
Mild edematous / fluid signals are seen along myofascial planes of distal posterior fibers
of biceps femoris and proximal fibers of gastrocnemius muscles. Rest of the visualised muscles
reveal normal signal intensity.
Mild circumferential periarticular subcutaneous edema is seen.
IMPRESSION- Non visualisation of ACL, likely represent chronic complete tear.
- Grade I MCL injury (sprain).
- Tear of both menisci.
- Mild to moderate joint effusion.
- Early osteoarthritis of knee.
- Element of femoral trochlear dysplasia.
Clinical correlation is suggested.

Two days back she has again fallen while washing clothes. Again the swelling has come at knees and lot of pain is there in knees. Please suggest what to do in this case.
Primarily Re construction of ACL Tear is required as an immediate procedure
Hi I am Dr Gopal Goel , Orthopedic Surgeon.
I have read the history and detailed report of MRI.Imp points are:
1.MRI report is significant for it reports complete tear of ACL( Anterior Cruciate Ligament)-- It is primarily this ligament which causes stability in the joint. At her age (42 yrs) she must undergo surgery for reconstruction of ACL to restore stability.
2.While the surgeon is doing arthroscopic examination he will be in a better position to evaluate both menisci and if required will do partial meniscectomy.
3. Cartilage defects are a sign of Osteoarthritis and can be treated at a later stage.
4.Grade 1 MCL injury will heal over time without surgical intervention.
5. Joint effusion will improve once healing of all tissues has undertaken.
Once again I suggest immediate treatment of Anterior Cruciate Ligament.
I hope to have answered all your queries. Pl don't hesitate to ask any question.
only surgery is useful
Hi I am Dr Gopal Goel Orthopedic Surgeon.
ACL tear can not be treated without surgery. Only surgical reconstruction(not Repair) is the answer. It will be done through arthroscopy and results are generally good. The cost will depend on the center and the endo buttons used . but roughly it should cost around 1.2 L. Post surgery walking can be started next day , with support , and most important is physiotherapy.
All the best for surgery and recovery.
Hi I am Dr Gopal Goel ,Orthpedic surgeon
Recurrent knee dislocation is very uncommon condition. If it is recurrent dislocation of patella(which is more likely as indicated by shallow groove in MRI) - It may require additional surgery. Too many operations at one time will lead to post operative adhesions and stiffness. But Ask your surgeon to look for any other finding. The treatment for recurrent dislocation of patella can be undertaken at a later stage.
Hope this answers your query.
