This pilot study compared efficacy, morbidity, and complication rates with a new single-portal arthroscopy technique and traditional 2-portal knee arthroscopy. This prospective study evaluated 156 patients who underwent arthroscopic knee surgery, 106 with 2 portals and a traditional arthroscope and instruments and 50 with a single portal and newly designed arthroscopy instruments. Patients who ...

INTRODUCTION The posterior portion of the knee joint, which includes the tibial attachment of the posterior cruciate ligament and the posterior horn of the menisci, has been called a "blind spot" because it is difficult to observe this area under arthroscopy through standard anterior portals. Posteromedial, posterolateral, and posterior transseptal portals have been developed for visualization ...

Accurate portal placement is crucial in diagnostic and therapeutic shoulder arthroscopy. However, knowledge of anatomy and surgical principles may not be enough. Placement of a second portal is often hindered by a small amount of bleeding. Our technique easily rectifies this frequent problem by using a simple mini-vent.

Hindfoot pain can be caused by any part of the posterior ankle anatomy with bony and soft tissue, including os trigonum, large posterior talar process, tenosynovitis of the flexor hallucis longus tendon, osteochondral lesions of the talus, subtalar arthritis and arthrosis, prominent calcaneus posterior process and free bodies, such as synovial chondromatosis. Because these structures are deeply...

PURPOSE To evaluate the proximity to the radial nerve on cadaveric specimens of 2 modified anterolateral portals used for elbow arthroscopy. METHODS Ten fresh cadaveric elbow specimens were prepared. Four-millimeter Steinman pins were inserted into 3 anterolateral portal sites in relation to the lateral epicondyle: (1) the standard distal anterolateral portal, (2) a modified direct anterolate...

Posteromedial portals in the knee are used for numerous procedures, including posterior cruciate ligament reconstructions, meniscal transplantation, repair of posterior meniscal tears, removal of loose bodies, and synovectomy. Iatrogenic injury to the sartorial branch of the saphenous nerve is a known complication of posteromedial portal arthroscopy; thus, a reproducible technique for creating ...

We describe a medial midline portal between the tendons of extensor hallucis longus and tibialis anterior for arthroscopy of the ankle. We dissected 20 cadaver specimens to compare the risk of neurovascular injury using this approach with that of using standard arthroscopic portals. Compared with the anterocentral portal, the medial midline was a mean of 11.2 mm further from the nearest branch ...
