Magnetic resonance imaging findings in a cat with cranial cruciate ligament rupture

Abstract

This case report describes the magnetic resonance imaging (MRI) findings of a 10‐year‐old cat with hind limb lameness due to cranial cruciate ligament rupture. The pre‐operative MRI findings about the absence of cranial cruciate ligament, intra‐articular mineralizations and joint effusion were confirmed during intra‐articular surgery, in which reconstruction of the cranial cruciate ligament using a string of fascia lata led to an excellent outcome for the patient. MRI could be useful for diagnosing a ruptured cranial cruciate ligament in cats. To our knowledge, this is the first reported use of MRI to diagnose cranial cruciate ligament rupture in cats, with intra‐operative confirmation of the imaging findings.

Knee Joint Osteoarthritis in Overweight Cats: The Clinical and Radiographic Findings

“…Thus, further research should include the assessment of stress indicators or the collection of data on stress behaviors in history. The imaging diagnostics of feline knee joint OA should be extended by using more accurate modalities such as computed tomography [51,73] and magnetic resonance imaging [74], as it is in humans [75,76] and dogs [77]. Although conventional radiography is still the first-choice imaging modality in the diagnosis and follow-up of feline OA [9,78], its significant drawbacks such as low sensitivity and poor correlation with clinical status support the dissemination of CT-and MRI-based OA diagnosis [79].…”

Isolated medial meniscal tear in a domestic shorthaired cat

“…A scan of both stifle joints at the same time may be used for a comparative examination. 14 Arthroscopy is reportedly the most sensitive and specific diagnostic method for detection of meniscal pathology in dogs. 23 Although stifle arthroscopy has been described in the cat, 2 the technique was also found to lead to more iatrogenic articular cartilage damage in a cadaveric study when compared to arthrotomy, as a means of exploration of the stifle joint in dogs.…”

“…The quality of feline stifle MRI scans can be improved using a small suitable coil and increasing the number of averages. A scan of both stifle joints at the same time may be used for a comparative examination 14 …”

“…Meniscal integrity can be investigated via non-invasive diagnostic modalities such as magnetic resonance imaging (MRI), or surgically via arthrotomy or arthroscopy. 14 Classification of meniscal lesions addresses the appearance, location, shape and extent. 15 The literature describes vertical longitudinal tears between tibial and femoral surface, including displaced bucket handle tears, oblique or flap tears, radial tears, horizontal or horizontal cleavage tears, complex and degenerative tears.…”

“…Meniscal tears can be suspected in clinical examination, but further investigations are necessary for a definitive diagnosis. Meniscal integrity can be investigated via non‐invasive diagnostic modalities such as magnetic resonance imaging (MRI), or surgically via arthrotomy or arthroscopy 14 . Classification of meniscal lesions addresses the appearance, location, shape and extent 15 .…”
