The knee: bone marrow abnormalities.

MRI is clearly the imaging modality of choice for detecting and exploring joint, osseous, and soft tissue injuries in the lower extremity and throughout the musculoskeletal system. Its ability to detect and differentiate the various forms of marrow pathology is unrivaled, and as such it should be obtained early in the work-up of a patient with a suspected marrow abnormality. Additionally, the radiologist must be familiar with the MRI appearances of normal marrow and the most common types of marrow pathology if its diagnostic power is to be fully realized.

Intra-articular migration of a sutureless arthroscopic rotator cuff fixation device.

Rotator cuff tears are a common orthopaedic condition. Recent new advances in arthroscopic equipment and devices has allowed many rotator cuff tears to be repaired arthroscopically. Some of these newer devices allow sutureless repair of rotator cuff tears. We report a case of failure in intra-articular migration of such a fixation device. Displacement of the device was noted 4 months after surgery on magnetic resonance arthography. The device was removed arthroscopically with no long-term sequelae. Nevertheless, it is important to recognize that these devices have the potential for intra-articular migration. Due diligence is required in placing these devices. As with all arthroscopic procedures, there appears to be a learning curve associated with the use of sutureless rotator cuff repair fixation devices.
