Sang-Hoon Lhee, Anant Kumar Singh, Do Young Lee
BACKGROUND: This study was conducted to determine whether supraspinatus muscle atrophy appearance changes after arthroscopic rotator cuff repair and to quantify the change in appearance on magnetic resonance imaging (MRI), if any, based on age and tendon retraction. METHODS: We retrospectively reviewed patients who underwent arthroscopic rotator cuff repair and considered only 209 patients who had both preoperative and immediate postoperative MRI. Patients were grouped by age <60 years and >60 years...

BACKGROUND: This study investigated the morphologic changes in the biceps tendon using ultrasonography before and after successful arthroscopic posterosuperior rotator cuff repair. METHODS: Forty-four patients (44 shoulders) underwent arthroscopic posterosuperior rotator cuff repair with 1-year postoperative magnetic resonance imaging (MRI) follow-up. The patients comprised 22 men and 22 women with an average age of 61 years. The cross-sectional area (CSA) of the biceps tendon in the bicipital groove was measured, and the vascularity in the bicipital groove was graded as 0 to 3, based on the signal density of the anterior circumflex artery, using power Doppler ultrasonography...

Orestis Karargyris, Vipul Mandalia
Surgical treatment of recalcitrant patellar tendinopathy includes both the open surgical approach and minimally invasive arthroscopic debridement. A variety of arthroscopic techniques have been described that involve the use of a standard 30° arthroscope and standard anterolateral and anteromedial portals. As a result, visualization of the infrapatellar region can be variable, and it may be necessary to create additional portals. A 70° arthroscope provides the advantage of a wider field of view to the surgeon...

Tendinopathy of the long head of the biceps is often found as an intra-articular pathology in the glenohumeral joint. Because long head of the biceps lesions are common, surgical intervention to properly manage the long head of the biceps has become an important issue. Both tenodesis and tenotomy have been shown to provide benefits in biceps long head tendinopathy. But because of concerns about muscle power reduction, cramping, and "Popeye's deformity," which may result from biceps tenotomy, biceps tenodesis is a good option for treating biceps lesions...

In a select group of patients with proximal anterior cruciate ligament (ACL) tears, primary repair can be a useful technique. Preservation of the native ACL may be advantageous for proprioceptive function and is thought to restore normal knee joint kinematics. The procedure is a less morbid and more conservative surgical approach to restore knee stability. Primary repair is preferably performed in the acute setting because of better healing capacity and tissue quality. We present the surgical technique of arthroscopic primary ACL repair with suture anchors in patients with proximal tears and excellent tissue quality...

Acquisition of arthroscopic skills is not always easy and can be time-consuming. Simulation in arthroscopy improves surgical skills and can bridge the gap between reduced surgical exposure and training time and the need to reach a required level of competency. We propose a method to create a simple and cost-effective arthroscopic skills simulator using readily available materials and a low-cost Web camera available from online shops. This arthroscopic simulation device can be used to improve skills of all levels of trainees at home, in a bioskills laboratory, or in the theater...

Idiopathic adhesive capsulitis of the shoulder is a relatively common condition that results in pain and loss of motion due to capsular thickening and fibrosis. Most cases are successfully treated with conservative management including physical therapy and intra-articular steroid injections. If conservative management fails, arthroscopic capsular release allows precise release of thickened capsular tissue with a lower risk of complications and less soft-tissue trauma than manipulation under anesthesia alone...

The purpose of this study is to present a "smart," open, minimally invasive surgical technique for rotator cuff repair of the shoulder. On the basis of an anatomic study by Tichy, we use a coracoacromial mobile window: We split-not detach-the deltoid muscle by respecting its fibers' orientation and resect the coracoacromial ligament before repairing the torn rotator cuff tendons with anchors. The described approach is fast, is technically uncomplicated, and can be carried out with a standard set of instruments...

Many of the described labral-reconstruction procedures are purely arthroscopic. This approach only allows segmentary reconstructions. For more extensive reconstructions, surgical dislocation of the hip still represents the more suitable approach. We present an arthroscopy-assisted procedure combined with an anterior mini-open approach, which could be considered for reconstruction of nonrepairable labral lesions located in the posterior aspect of the acetabulum and massive reconstructions in cases of global-pincer femoroacetabular impingement and protrusio acetabuli...

Recent advances to improve outcomes in rotator cuff repair include using arthroscopic double-row suture-bridge techniques in an effort to reconstruct the rotator cuff footprint and improve fixation. However, when using this technique for larger tears, it can be difficult to get the lateral portion of the rotator cuff into an anatomic position. This report describes a triple-row modification of the suture-bridge technique that results in significantly more footprint contact area and contact pressure compared with the double-row and standard suture-bridge techniques...

Atraumatic instability of the hip has become an increasingly studied occurrence in recent years. There are several established surgical techniques that help restore stability of the native hip joint. In some cases, these procedures are not an option. As the phenomenon has become recognized more frequently, a greater number of revision surgeries are warranted in patients with ligamentous laxity. A durable solution for irreparable microinstability needs to be formulated to address this vulnerable patient demographic...

Femoral head fractures after posterior dislocation of the hip are uncommon and are conventionally treated by an open method. Hip arthroscopy can be a valuable treatment option for the management of femoral head fractures. Arthroscopy allows for a less invasive option when compared with arthrotomy and can allow faster recovery with minimal soft-tissue injury. We describe the arthroscopic reduction and internal fixation of Pipkin type I femoral head fractures with a detailed stepwise description of the surgical technique, including technical pearls and pitfalls, potential complications, and advantages and disadvantages...

Bassem T Elhassan, Eduard Alentorn-Geli, Andrew T Assenmacher, Eric R Wagner
Tendon transfer options to reconstruct a massive irreparable posterior-superior rotator cuff tear include latissimus dorsi, teres major, or lower trapezius transfer. We previously described the lower trapezius transfer using a 2-incision approach, which includes a medial incision to harvest the lower trapezius and lateral transacromial incision to expose the rotator cuff and then perform the transfer through a deep tunnel connecting these 2 sites. In this report, we describe an arthroscopic-assisted technique of lower trapezius transfer augmented with an Achilles tendon allograft to reconstruct an irreparable posterior-superior rotator cuff tear...

Glenoid osteochondral defects can be a significant source of pain and disability in an active population. Many treatments are available, but most joint-preserving procedures are limited to debridement, abrasion chondroplasty, or marrow-stimulation techniques, all of which depend on healthy underlying bone and none of which address underlying bony pathology. Osteochondral autograft transfer has been a successful form of treatment for lesions in the knee, elbow, and ankle, especially when subchondral bone is involved...

Nata Parnes, Maryellen Blevins, Monica Morman, Paul Carey
Arthroscopic capsulolabral repair during shoulder stabilization surgery requires the use of suture anchors. Several arthroscopic suturing techniques for capsulolabral repair have been described, and each carries very specific advantages and disadvantages with regard to risk, patient satisfaction, and functional outcomes. The purpose of this report is to describe the oblique mattress lasso-loop stitch. This stitch (1) provides strong initial fixation of the labrum, (2) establishes labral height and allows for larger capsular plication if needed, (3) prevents the suture from cutting through the radial fibers of the glenoid labrum, (4) prevents knot migration to the articular side and loosening of the knot, and (5) requires fewer implants and preserves glenoid bone stock by increasing the amount of labrum and capsule that can be reattached to the glenoid with a single-loaded suture anchor...

BACKGROUND: Shoulder arthroscopic arthrodesis is an uncommon and non-standardized procedure. Results are poorly evaluated. We describe the findings in 8 patients who underwent shoulder arthroscopic arthrodesis for brachial plexus injury. METHODS: The humeral head and glenoid were excised through standard arthroscopic portals. A Hoffmann external fixator and cannulated screws were used to stabilize the shoulder. Standard clinical assessment and radiographic evaluation were performed each month until bony fusion occurred...

PURPOSE: The physical examination of the shoulder is usually not reliable for the true diagnosis of superior glenoid labrum anterior to posterior (SLAP) lesions. Magnetic resonance imaging (MRI) has been routinely used for the diagnosis. This prospective study investigates the radiological diagnosis of the SLAP lesions and compares accuracy of arthroscopic and MRI classifications. METHODS: One hundred thirty-two patients with positive physical examination signs using O'Brien, Yergason, resistance supination external rotation and Krank tests and MRI findings are included in the study...
