BACKGROUND Hundreds of thousands of surgical arthroscopy procedures are performed annually in the United States (US) based on MRI findings. There are situations where these MRI findings are equivocal or indeterminate and because of this clinicians commonly perform the arthroscopy in order not to miss pathology. Recently, a less invasive needle arthroscopy system has been introduced that is comm...

Evaluation of the feasibility of virtual magnetic resonance (MR) arthroscopy was performed on 10 patients referred for MR arthrography of the shoulder, the elbow, or the knee. A fast spoiled contrast-enhanced three-dimensional gradient-echo sequence was combined with image postprocessing to render arthroscopic views. Virtual MR arthroscopy was successfully demonstrated in all 10 joints. Determi...

We report a case of inferior lateral genicular artery (ILG) injury during anterior cruciate ligament (ACL) reconstruction surgery with lateral partial meniscectomy. This is a rare arthroscopy complication. A review of the literature has been made with the aim to define the anatomy of ILG across the lateral articular line and the risk of lesion during knee arthroscopy. We propose embolization as...

Purpose Parallel imaging allows for a considerable shortening of examination times. Limited data is available about the diagnostic accuracy of an accelerated knee MRI protocol based on parallel imaging evaluating all knee joint compartments in a large patient population compared to arthroscopy. Materials and Methods 162 consecutive patients with a knee MRI (1.5 T, Siemens Aera) and arthroscopy ...

A 28-years old lady complains of self-limited episodes of relapsing knee arthritis of 48-72h of duration every 2 weeks. Immunological profile was all negative. At the same time, radiological images did not reveal any abnormality. She underwent to knee arthroscopy, however, a definite diagnosis was not reached. We discuss the differential diagnosis of relapsing arthritis.

BACKGROUND There are many different materials used for ligament reconstruction. Currently, autograft, allograft, and artificial ligaments are used in the reconstruction. The objective of this study was to explore the clinical result of cruciate ligament reconstruction under arthroscopy. METHODS Eighty-one cases were reconstructed with the LARS ligament under arthroscopy, including 43 cases of...

Minimally invasive surgery (MIS) has many documented advantages, but the surgeon’s limited visual contact with scene can be problematic. Hence, systems that help surgeons navigate, such as a method produce 3D semantic map, compensate for limitation above. In theory, we borrow mapping techniques developed robotics, this requires finding solutions to following challenges in MIS: 1) segmentation, ...

CONTEXT A ganglion is a cystic formation close to joints or tendinous sheaths, frequently found in the wrist, foot or knee. Intra-articular ganglia of the knee are rare, and most of them are located in the anterior cruciate ligament. The clinical picture for these ganglia comprises pain and movement restrictions in the knee, causing significant impairment to the patient. Symptoms are non-specif...

PURPOSE The purpose of this OTA-approved pilot study was to compare the clinical and functional outcomes of the knee joint after infrapatellar (IP) versus suprapatellar (SP) tibial nail insertion. DESIGN Prospective, randomized. SETTING Level I trauma center. METHODS After institutional review board approval, skeletally mature patients with OTA 42 tibial shaft fractures were randomized in...
