When are about the same, the only difference

Whenlooking at MRI in comparison to arthroscopy, overall, they have about the same resultsfor diagnosing tears, with arthroscopy being just a little more efficient. Butkeeping in mind the risk factors of choosing the route of arthroscopy. Somerisk factors may be minor, but they can be as harmful as deep tissueinfections, nerve damage, or pulmonary embolism. Most of the studies you findon the comparison the results are about the same, the only difference being theopinion on whether to take the chance and risks to go forward with the invasivearthroscopic procedure or just stick with MRI with little to no side effects.”MRI is now commonly used before diagnostic arthroscopy in most settings and isconsidered an effective screening tool in most patients because it is faster,non-invasive and does not involve morbidity associated with arthroscopy” (——).

  Overallmost of the research says for a more complex look at the soft tissue and tearsof the joints MRI is the better way to go.Arthroscopyis used to exam joints. Mostly Physicians use it for looking at structuresinside the joint. It is performed by inserting an arthroscope into the jointthrough a small incision. The arthroscope allows surgeons to see damagedligaments. There are some risks to arthroscopy like infection, swelling orblood clots. “Occasionally, arthroscopy may reveal no abnormality in the ACL” (——).

  So is itworth it to do an invasive procedure if it doesn’t show a tear in the ligaments? AnMRI is used to find a more accurate diagnosis of disease and tear thatdiagnostic imaging will not see. Although an MRI scan is not the first placemost Physicians send trauma patients, it will give good information fordiagnosis for example on the brain, spine and heart/aorta. They also are notquick easy scans they are time consuming and hard for not only trauma patientsbut for everyone it’s hard for patients to stay still for at least an half hoursometimes even longer depending on the scan. Sometime surgeries can bepostponed with getting the images from the scan. MRI’s are painless and have noside effects. Goinga little further into the knee joint anatomy.

The knee is a synovial joint arethere for movement like in your hands, the joint contains synovial fluid, whichhelps to lubricate the joint to it doesn’t rub to reduce friction. The ends ofthe bones in the knee joint are covered in articular cartilage which also helpsthe bones to move and slide without damaging the any part of the joint. Theknee joint is a weight bearing joint that provides stability and balance. Themain focus of this paper is the ACL.

“The anterior cruciate ligament (ACL) is adense fibrous band composed of collagen fibrils. It is approximately 3.5-3.8 cmlong and i cm in transverse diameter” (——-).  Overallthe knee is a very complicated joint and there is still much more for everyoneto learn about it. The human body is a complexliving 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 kneejoint is one of the most complex joints in the human body” (———).

It iscomprised of three major bones the femur, fibula, tibia and also the patella.Many different ligaments hold the joint together such as the lateral collateralligament, medial meniscus, patellar ligament and more. Knee injuries are verycommon and are not just a fracture or a break, a more common injury is a tornligament or tendon, the most common ligament that people and athletes injure istheir ACL (anterior cruciate ligament). You see these tears occur by a suddentwist motion, people who most commonly injure their ACL play high demand sportssuch as football, soccer or lacrosse. Some of the signs to look for with an ACLtear are swelling, pain or discomfort when you try to walk.

You may also hear atype of popping sound when it gets torn. There are many steps you must take todetermine 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 firstsee if something is wrong with any of the bones of the knee. Moving onafterward you will get an MRI (Magnetic Resonance Imaging) scan done.

MRI’s area type of medical imaging that use radio waves and a computer to get images ofthe body and unlike x-ray it shows soft tissue. When trying to find the bestway to diagnosis and treat an ACL tear MRI is the best option but is an MRImore efficient compared to arthroscopy. “MRI is a noninvasive, radiation freemodality with a better ability to asses’ soft tissue. Arthroscopy has adiagnostic accuracy of 64 to 94% but is an invasive procedure and is associatedwith complications” (——-).
