Iliotibial Band Tenodesis With a Tenodesis Screw for Augmentation of Anterior Cruciate Ligament Reconstruction

Anterior cruciate ligament reconstruction with lateral extra-articular tenodesis using a strip of the iliotibial band (ITB) has been shown to increase postoperative stability of the knee. This Technical Note describes a method of ITB tenodesis in which a central slip of the ITB is passed deep to the lateral collateral ligament and then rerouted anteriorly for fixation at a location anterior and proximal to the lateral femoral epicondyle. Five whipstitches are passed through the ITB, and a second distal suture is tied around the distal end. Of the 4 suture tails, 3 are passed through a tenodesis screwdriver, and the screw is placed in the previously reamed bone socket. A closed loop is formed around the tenodesis screw by tying off the suture tails. This technique creates a sling around the lateral collateral ligament, which serves as a checkrein to internal rotation in cases in which increased stability is warranted, such as revision anterior cruciate ligament reconstruction in an athlete

Arthroscopic Technique for the Treatment of Pigmented Villonodular Synovitis of the Hip

Open synovectomy remains the treatment of choice for pigmented villonodular synovitis (PVNS) of the hip but has shown modest results compared with the treatment of other joints. Recent advances in hip arthroscopy permit a thorough evaluation of the joint surfaces, improved access, and decreased postoperative morbidity. We describe an arthroscopic synovectomy technique for PVNS of the hip. The use of additional arthroscopic portals and creation of a large capsulotomy enable successful visualization and extensive synovectomy of the entire synovial lining of the hip. The T-capsulotomy enables extensive soft-tissue retraction for complete exposure. The midanterior portal enables use of an arthroscopic grasper and shaver to directly access and excise the synovial lining of the peripheral compartment while avoiding damage to the medial and lateral retinacular vessels. Technical innovations in hip arthroscopy have enhanced visualization in the central and peripheral compartments, as well as instrument management and diagnostic evaluation of the capsule, therefore allowing enhanced management of PVNS of the hip

All-Endoscopic Single-Row Repair of Full-Thickness Gluteus Medius Tears

Abductor tendon tears typically develop insidiously in middle-aged women and can lead to debilitating lateral hip pain and a Trendelenburg limp. The gluteus medius tendon is most commonly torn and may show fatty degeneration over time, similar to the rotator cuff muscles of the shoulder. Endoscopic repair offers a therapeutic alternative to traditional open techniques. This article describes the workup, examination, and endoscopic repair of a full-thickness gluteus medius tear presenting as lateral hip pain and weakness. The surgical repair for this case used a single-row suture anchor technique. In addition, the indications and technique for a double-row repair will be discussed

ACL Reconstruction Basics: Quadruple (4-Strand) Hamstring Autograft Harvest

Hamstring tendon autograft remains a popular graft choice for anterior cruciate ligament (ACL) reconstruction. Although there are a variety of autograft and allograft options available for ACL reconstruction, advantages of hamstring tendon autografts include decreased postoperative knee pain and an overall easier surgical recovery compared with bone patellar tendon bone autograft. In addition, 4-stranded (quadruple) hamstring grafts are among the strongest grafts biomechanically (at time equals zero). Although the technique of hamstring autograft harvest is relatively straightforward, it is critical to pay attention to several technical steps to avoid iatrogenic neurovascular damage as well as to avoid premature amputation of the graft while using a tendon stripper. In this Technical Note, we describe a technique of hamstring autograft harvest for ACL reconstruction for a quadruple (4-strand) hamstring graft using the gracilis and semitendinosus tendons

Diagnosis, Evaluation, and Endoscopic Repair of Partial Articular Gluteus Tendon Avulsion

In addition to trochanteric bursitis, gluteus medius and minimus tears (GMMTs) can be a common source of insidious lateral hip pain and dysfunction. Partial-thickness GMMTs are much more common than full-thickness GMMTs but are frequently overlooked by both radiologists and orthopaedic surgeons. GMMTs are commonly identified on magnetic resonance imaging ordered for lateral hip pain unresponsive to conservative management. Imaging can show that high-grade partial articular gluteus tendon avulsion (PAGTA) can occur as either an isolated gluteus medius tear, an isolated gluteus minimus tear, or a combined GMMT. We describe how to identify PAGTA injuries with intraoperative assessment and identification of the interval between the gluteus medius and minimus tendons to allow access to the PAGTA without violating the bursal side of the tendon. PAGTAs can be repaired arthroscopically by single- or double-row suture anchor fixation depending on the size of the tear. The purpose of this article is to guide orthopaedic surgeons in the recognition of PAGTA with magnetic resonance imaging and dynamic examination to allow for accurate repair of GMMTs
