The type of contrast injected into the joint depends on the subsequent imaging that is planned. For pneumoarthrography, gas is used, for CT or radiographs, a water-soluble radiopaque contrast, and for MRI, gadolinium. Double-contrast arthrography can be used for more anatomically complex cases, though its use is relatively infrequent.
The knee joint contains two crescent-shaped fibrocartilaginous structures, the menisci (medial and lateral), which serve as shock absorbers and stabilize the joint during movement. Each meniscus has an outer vascular zone (red-red zone), which has a good blood supply and healing potential as well as a central avascular zone (white-white zone ...
A specialized growing subset of interventional MRI is intraoperative MRI, in which an MRI is used in surgery. Some specialized MRI systems allow imaging concurrent with the surgical procedure. More typically, the surgical procedure is temporarily interrupted so that MRI can assess the success of the procedure or guide subsequent surgical work ...
Knee injury doctors have long thought that a torn ACL required surgery to fix. New research suggests a non-surgical treatment may be as effective. Torn ACLs may heal with therapy instead of ...
The surgery is done with an arthroscope or tiny camera inserted inside the knee, with additional small incisions made around the knee to insert surgical instruments. This method is less invasive and is proven to result in less pain from surgery, less time in the hospital, and quicker recovery times than "open" surgery (in which a long incision ...
Knee arthroscopy, or arthroscopic knee surgery, is a surgery that uses arthroscopic techniques. It has, in many cases, replaced the classic open surgery that was performed in the past. Arthroscopic knee surgery is one of the most common orthopaedic procedures, performed approximately 2 million times worldwide each year. [2]
For the grading of osteoarthritis in the knee, the International Knee Documentation Committee (IKDC) system is regarded to have the most favorable combination of interobserver precision and correlation to knee arthroscopy findings. [10]
MRI can also show associated bone bruises on the lateral side of the knee, which one study shows, happen in almost half of medial knee injuries. [ 19 ] Knee MRIs should be avoided for knee pain without mechanical symptoms or effusion, and upon non-successful results from a functional rehabilitation program.
