PATELLA DISLOCATION SUBLUXATION HEMARTHROSIS FRACTURE DISCUSSION ON PATELLA DISLOCATION SUBLUXATION HEMARTHROSIS FRACTURE The patient has had a recent patella dislocation and there is now a large suprapatellar effusion (on MRI this was a hemarthrosis). On X-ray we can’t say defnitely that it’s a hemarthrosis but the presence of a fracture would indicate that it is …
KNEE PLICA MRI MEDIAL PATELLAR PLICA RADIOLOGY DISCUSSION WHAT IS THE MEDIAL PATELLAR PLICA? The medial patella plica is a developmental synovial membrane remnant. Can be seen in up to 30% of knees. IS IT SYMPTOMATIC? It can be completely asymptomatic but can extend between the patella and trochlea and be compressed and cause …
MENISCAL INTRAMENISCAL CYST MRI RADIOLOGY DISCUSSION INTRAMENISCAL CYST. Extensive intra meniscal cyst anterior horn. A tear is not seen extending to the articular margin. However we may not always see the extension on MRI. So if you see an intra-meniscal or parameniscal cyst these are always due to an underlying tear even if we don’t …

VERTICAL MENISCUS MENISCAL TEAR MRI KNEE DISCUSSION VERTICAL (LONGITUDINAL) MENISCUS TEAR POSTERIOR HORN. The high signal extends to both the superior and inferior articular margins of the meniscus indicating a tear. It can be easy to overlook peripheral vertical tears as the torn outer fragment (Green arrows) can be very thin and may not …
MENISCUS FIBRILLATION MRI LATERAL MENISCUS DISCUSSION This is NOT a tear. The anterior horn of the lateral meniscus as it approaches its insertion into the tibia is normally fibrillated like this and this is a normal finding. MENISCUS FIBRILLATION MRI LATERAL MENISCUS: MOVE SLIDER TO VIEW IMAGES ARE FROM OUR INSTAGRAM ACCOUNT. CLICK ICON …
POPLITEOMENISCAL FASICLES MRI TEAR NORMAL ANATOMY DISCUSSION These structures are the Popliteomeniscal Fascicles. They are the Antero Inferior Fascicle (Blue arrow). The Postero superior Fascicle (Pink arrow) which forms the, Popliteal Hiatus (Orange arrow) for the, Popliteus tendon (Green arrow) to pass through.

PATELLAR TENDON CONTUSION Patellar Tendon Contusion. In this case we have Patellar tendon contusion and Patella contusion. Most commonly this combined appearance would be of Patellar Tendonosis with reactive oedema in the patella and inflammatory change extending into Hoffa’s fat. However the history of trauma in this patient is important in being able …
MOVE SLIDER ICON (ARROWS) LEFT TO SEE THE DIAGNOSIS FINDINGS Bilateral medullary femoral and tibial serpiginous STIR hyper-intensity with extension into the femoral and tibial epiphysis. DIAGNOSIS MEDULLARY BONE INFARCTS. This is a characteristic appearance of medullary bone infarcts. Most commonly they are in the diaphysis and metaphysis but in this case they also extend …
MEDIAL COLLATERAL LIGAMENT MCL BURSA MRI DISCUSSION ON MCL BURSA Medial Collateral ligament MCL BURSA. The MCL bursa lies between the superficial MCL and the capsule and deep MCL. Whilst it’s present anatomically, usually its not seen on MRI and fluid is seen when there is bursitis. In this case it extends deep …
PROXIMAL TIBIOFIBULAR JOINT MRI ANATOMY MRI PROXIMAL TIBIO FIBULAR JOINT ANATOMY The proximal tibiofibular joint is often overlooked when assessing a knee MRI. This is the first in a series on MRI of the proximal tibiofibular joint (PTFJ) beginning with the anatomy of the ligaments that stabilize the PTFJ. WHAT'S THE PROBLEM Often overlooked when …
