Combined Intra-articular and Extra-articular Visualization for Repair of a Complete Subscapularis Tear: The "Blended View" Technique.

ABSTRACT: Repair of subscapularis tendon tears can be a challenging task, even for an experienced arthroscopist. The complexity results not only from the difficulty in identifying these tears accurately but also because establishing orientation for visualization and repair of this often distorted anatomy can be difficult. Even after a subscapularis tear is identified and mobilized, restoration of the footprint can prove demanding due to the limited view of the subscapularis tendon's lesser tuberosity insertion site, especially from the traditional posterior portal. Such visualization limitations often necessitate switching back and forth between 30° and 70° arthroscopes. A "blended view" technique is used routinely because it offers optimal visualization and access to the subscapularis tendon and the lesser tuberosity during full-thickness subscapularis repair.

Project description:Tibial anterolateral rotary instability associated with anterior cruciate ligament (ACL) tears is a well-documented and difficult problem with a long history of solutions. The lateral extra-articular tenodesis (LET) has undergone multiple refinements in technique, largely focusing on the femoral site insertion using either an interference screw versus a staple for adequate fixation. In this article, we present an improved technique using a suture anchor as an alternative to a staple or an interference screw with secure fixation to insert the LET graft onto the femur. This technique diminishes the chance of ACL tunnel–LET drilling convergence, minimizes the footprint required for adequate graft fixation, and allows the surgeon to dial in the correct tension necessary for adequate augmentation of an ACL reconstruction. Technique Video Video 1 Onlay technique of lateral extra-articular tenodesis (LET). The lateral aspect of a right knee is shown, with the patient positioned supine. The surgeon performs an approach to the iliotibial band, removing all subcutaneous tissue for adequate exposure starting approximately at the Gerdy tubercle and extending proximally about 8 cm. A distally based strip of the iliotibial band is harvested, approximately 1 cm in width, by use of separate incisions. A double-loaded 2.3-mm Iconix all-suture suture anchor is used for LET graft insertion. The graft is whipstitched with an arm of the suture anchor that is first passed underneath the lateral collateral ligament, followed by a simple suture pass through the graft by the other end of the same arm of the suture attached to the suture anchor. The fixation with 1 arm of the double-loaded Iconix suture anchor was enough to secure the graft appropriately, and the other suture within the double-loaded 2.3-mm Iconix suture anchor was removed prior to definitive fixation of the LET graft. Once the LET graft was appropriately stitched, the graft was passed underneath the lateral collateral ligament again, from distal to proximal, and then secured to the Iconix suture anchor.
