When are about the same, the only difference

looking at MRI in comparison to arthroscopy, overall, they have about the same results
for diagnosing tears, with arthroscopy being just a little more efficient. But
keeping in mind the risk factors of choosing the route of arthroscopy. Some
risk factors may be minor, but they can be as harmful as deep tissue
infections, nerve damage, or pulmonary embolism. Most of the studies you find
on the comparison the results are about the same, the only difference being the
opinion on whether to take the chance and risks to go forward with the invasive
arthroscopic procedure or just stick with MRI with little to no side effects.
“MRI is now commonly used before diagnostic arthroscopy in most settings and is
considered an effective screening tool in most patients because it is faster,
non-invasive and does not involve morbidity associated with arthroscopy” (——).  Overall
most of the research says for a more complex look at the soft tissue and tears
of the joints MRI is the better way to go.

is used to exam joints. Mostly Physicians use it for looking at structures
inside the joint. It is performed by inserting an arthroscope into the joint
through a small incision. The arthroscope allows surgeons to see damaged
ligaments. There are some risks to arthroscopy like infection, swelling or
blood clots. “Occasionally, arthroscopy may reveal no abnormality in the ACL” (——).  So is it
worth it to do an invasive procedure if it doesn’t show a tear in the ligaments?

MRI is used to find a more accurate diagnosis of disease and tear that
diagnostic imaging will not see. Although an MRI scan is not the first place
most Physicians send trauma patients, it will give good information for
diagnosis for example on the brain, spine and heart/aorta. They also are not
quick easy scans they are time consuming and hard for not only trauma patients
but for everyone it’s hard for patients to stay still for at least an half hour
sometimes even longer depending on the scan. Sometime surgeries can be
postponed with getting the images from the scan. MRI’s are painless and have no
side effects. 

a little further into the knee joint anatomy. The knee is a synovial joint are
there for movement like in your hands, the joint contains synovial fluid, which
helps to lubricate the joint to it doesn’t rub to reduce friction. The ends of
the bones in the knee joint are covered in articular cartilage which also helps
the bones to move and slide without damaging the any part of the joint. The
knee joint is a weight bearing joint that provides stability and balance. The
main focus of this paper is the ACL. “The anterior cruciate ligament (ACL) is a
dense fibrous band composed of collagen fibrils. It is approximately 3.5-3.8 cm
long and i cm in transverse diameter” (——-).  Overall
the knee is a very complicated joint and there is still much more for everyone
to learn about it. 

The human body is a complex
living organism made up of many different bones, muscles, tendons and more.
Each bone or muscle plays a key role into your everyday life, but “the knee
joint is one of the most complex joints in the human body” (———). It is
comprised of three major bones the femur, fibula, tibia and also the patella.
Many different ligaments hold the joint together such as the lateral collateral
ligament, medial meniscus, patellar ligament and more. Knee injuries are very
common and are not just a fracture or a break, a more common injury is a torn
ligament or tendon, the most common ligament that people and athletes injure is
their ACL (anterior cruciate ligament). You see these tears occur by a sudden
twist motion, people who most commonly injure their ACL play high demand sports
such as football, soccer or lacrosse. Some of the signs to look for with an ACL
tear are swelling, pain or discomfort when you try to walk. You may also hear a
type of popping sound when it gets torn. There are many steps you must take to
determine whether you have an ACL tear, starting with diagnostic imaging.
Usually one of the first steps the Physicians will take is getting x-rays done.
Although x-rays will not show you if the ligament has been torn, it will first
see if something is wrong with any of the bones of the knee. Moving on
afterward you will get an MRI (Magnetic Resonance Imaging) scan done. MRI’s are
a type of medical imaging that use radio waves and a computer to get images of
the body and unlike x-ray it shows soft tissue. When trying to find the best
way to diagnosis and treat an ACL tear MRI is the best option but is an MRI
more efficient compared to arthroscopy. “MRI is a noninvasive, radiation free
modality with a better ability to asses’ soft tissue. Arthroscopy has a
diagnostic accuracy of 64 to 94% but is an invasive procedure and is associated
with complications” (——-).
