Examination of the Knee

Inspection Inspection is only possible with adequate exposure. Begin by placing the patient in shorts or tying the gown up above the knee. The patient’s gait should be observed first. Pay attention to the positioning of the knee on both the medial/lateral plane (valgus vs. varus) and the anterior/posterior plane (extension lag vs. knee recurvatum). […]

Anserine Bursa Injection

Indications Anserine bursa injection is a useful diagnostic and therapeutic procedure in bursitis resulting from osteoarthritis or direct trauma. Pain is noted inferior to the anterior medial surface of the knee when climbing stairs. Pain is reproduced with the knee in flexion-extension while internally rotating the leg. Techniques After informed consent is obtained, the patient […]

Knee Joint Injection

Tiếng Việt >> Indications Intraarticular corticosteroid injection of the knee joint is used to treat noninfective inflammatory joint disease secondary to rheumatoid arthritis, seronegative spondyloarthritides, or the chondrocalcinosis inflammatory phase of osteoarthritis. Techniques After informed consent is obtained, the patient is placed in the sitting position with the knee flexed to 90 degrees. The patellar […]

Other Knee Abnormalities

Patellar tendinitis (jumper’s knee) is demonstrated by MRI as an area of edema within the patellar ligament (i.e., tendon) at its patellar (Fig. 6-28) or tibial tuberosity attachment. There is also associated edema in the adjacent subcutaneous fat or the infrapatellar fat pad. FIGURE 6-28. Sagittal T2-weighted fat suppressed image of patellar tendinitis. The arrow […]

Collateral Ligament Injuries

The collateral ligaments are best visualized by coronal MR images (Fig. 6-27). The medial collateral ligament appears as a narrow low–signal-intensity band extending from the medial epicondyle of the femur to an attachment on the anteromedial aspect of the tibia 5 to 6 cm below the joint line. It is overlaid at its tibial attachment […]

Cruciate Ligament Injuries

The cruciate ligaments are best visualized by sagittal or oblique sagittal MR images that display the full length of the ligaments (Fig. 6-24A). On straight sagittal images, the slender nature of the anterior cruciate ligament and its oblique course cause a volume-averaging effect that averages fat signal intensity about the ligaments with the normal low […]

Meniscal Injuries of the Knee

All parts of both menisci are well visualized by MRI. Sagittal MR images provide good views of the anterior and posterior horns and a fair view of the body of both menisci. In more central sections, both horns of the menisci appear as wedge- shaped signal voids contrasted on their superior and inferior surfaces by […]
