Partial articular supraspinatus tendon avulsion (PASTA) tears are common. However, there is no consensus on the optimal surgical technique for the management of grade 3 tears (>50%). The authors report a retrospective consecutive case series of 64 patients with grade 3 PASTA lesions. The patients were treated by 2 surgeons from 2 centers with the same transtendon repair technique and implant system. The preoperative Oxford Shoulder Score (OSS) was compared with the postoperative OSS at final follow-up (mean, 28 months)...

Considering that optimal contact area and pressure at the tendon-bone interface are associated with better footprint repair and outcomes, the aim of this study was to compare the performance of standard double-row, transosseous equivalent (TOE), and partial articular supraspinatus tendon avulsion (PASTA) techniques for the treatment of full-thickness tears of the supraspinatus tendon using 3D finite element models. Loading consisted, alternately, in a preloading of 10 N and 20 N of the sutures. The footprint coverage of the standard double-row, TOE, and PASTA techniques was estimated to represent 19%, 30%, and 35%, respectively, of the repair area...

Partial-thickness articular-sided rotator cuff tears are a common cause of shoulder pain in adults. Although partial rotator cuff tears have a high prevalence, there is still controversy over their proper surgical treatment. Different surgical procedures have been suggested when partial tears involve the articular side of the rotator cuff, such as arthroscopic debridement of the tear with or without acromioplasty, tear completion and repair, and transtendinous in situ repair. Although multiple repair techniques have been described, significant clinical data to definitively support one technique over the others are currently lacking...

OBJECTIVES: Ultrasound (US) is useful for diagnosing full-thickness rotator cuff tears and high-grade partial-thickness bursal-side tears. However, anisotropy artifacts make it difficult to identify partial articular supraspinatus tendon avulsion (PASTA) by US. This study was performed to determine the diagnostic accuracy of US for PASTA and to uncover sensitive findings that could aid decisions to repair. METHODS: Patients who underwent preoperative US examinations and supraspinatus tendon confirmation by arthroscopic examinations were enrolled...

BACKGROUND: For the surgical treatment of severe partial articular surface tendon avulsion (PASTA) lesions, 2 repair techniques, i.e., arthroscopic trans-tendon repair and arthroscopic repair after conversion to a full thickness tear, are widely used, and a satisfactory clinical outcome with both has been reported. The purpose of this study was to investigate integrity of the repaired rotator cuff based on second-look arthroscopy and to compare the above two repair techniques. METHODS: Thirty-seven shoulders underwent PASTA lesion repair arthroscopically, with 20 shoulders receiving second-look arthroscopy...

Articular surface partial rotator cuff tendon tears are a common source of shoulder pain and dysfunction, and there is no consensus regarding the optimal arthroscopic treatment. Commonly accepted techniques, such as transtendinous repair or tear takedown with primary repair, may violate healthy tendon tissue and increase the suture anchor density. In this note, we describe an outside-in double row-equivalent technique for repair of partial articular-sided rotator cuff tears. A medial row of inverted horizontal mattress stitches is placed percutaneously using spinal needles to shuttle partially absorbable braided sutures into the joint...

The tricuspid valve (TV) has been known as the forgotten valve. However, considering recent information from scientific studies, this nomenclature may need to be adjusted for the valve, which also needs to be better studied and understood. For decades, tricuspid regurgitation (TR) was not fully appreciated and was never the priority. However, studies have revealed that such pathology is related to a possible negative impact on prognosis of patients. Severe TR is a predictor of higher mortality. For the treatment of TR, repair or valve replacement can be performed...

One of the obstacles standing before the biomechanical analysis of an ascending thoracic aortic aneurysm (ATAA) is the difficulty in obtaining patient-specific material properties. This study aimed to evaluate differences on ATAA-related stress predictions resulting from the elastostatic analysis based on the optimization of arbitrary material properties versus the application of patient-specific material properties determined from ex-vivo biaxial testing. Specifically, the elastostatic analysis relies the on the fact that, if the aortic wall stress does not depend on material properties, the aorta has to be statistically determinate...

Ascending thoracic aortic aneurysm (ATAA) in patients with bicuspid aortic valve (BAV) can present an asymmetrical aortic dilatation compared with patients with tricuspid aortic valve (TAV). This pattern of aneurysm dilatation led us to hypothesize that biomechanical differences likely induced by regional heterogeneity of material properties can underlie the observed asymmetric enlargement discrepancies between BAV ATAA and TAV ATAA. This study aimed to characterize the mechanical properties and associated aortic tissue stiffness changes along the circumferential direction of aortic rings collected from surgically-repaired patients with ATAA...

Partial articular-sided supraspinatus tendon avulsion (PASTA) tears are a common clinical problem that can require surgical intervention to reduce patient symptoms. Currently, no consensus has been reached regarding the optimal repair technique. The PASTA Bridge technique was developed by the senior author to address these types of lesions. A controlled laboratory study was performed comparing the PASTA Bridge with a standard transtendon rotator cuff repair to confirm its biomechanical efficacy. A 50% articular-sided partial tear of the supraspinatus tendon was created on 6 matched pairs of fresh-frozen cadaveric shoulders...

INTRODUCTION: Partial-thickness rotator cuff tears are a common cause of shoulder pain and disability. Arthroscopic repair is an effective treatment for partial articular supraspinatus tendon avulsion (PASTA) lesions, and transtendon repair and completion of the tear and repair are the surgical techniques commonly used to treat such lesions. Our aim was to retrospectively evaluate the minimum 24-month clinical and radiological results of PASTA. MATERIALS AND METHODS: Patients suffering from PASTA lesion who underwent arthroscopic repair with a minimum 24-month follow-up were included in this study...

PASTA (partial articular supraspinatus tendon avulsion) lesions of greater than 50% thickness are usually repaired, whereas those of less than 50% thickness receive subacromial decompression and debridement. However, tears of greater than 25% thickness of the tendon result in increased strain of the adjacent, intact tendon fibers. Re-creating the tendon footprint at the greater tuberosity is the goal of a repair. Transtendon repairs have been considered the gold standard in repair but have shown varying outcomes and are technically difficult procedures...

The simultaneous arthroscopic exposure of the subacromial and intra-articular space of the shoulder is challenging in the presence of only partial-thickness rotator cuff tears. We present our experience and method of entering the joint through the opened rotator cuff interval from an anterosuperior portal between the coracoid process and anterior acromion. With moderate (approximately 30°) abduction and external rotation, the rotator interval opens readily, offering a view with the camera toward the anterior edge of the supraspinatus tendon...

Background Specific findings on magnetic resonance arthrography (MRA) that indicate the need for surgery in patients with partial articular-sided supraspinatus tendon avulsion (PASTA) are not well understood. Purpose To determine which MRA findings are characteristic of patients who undergo surgery for PASTA. Material and Methods From July 2011 to February 2014, MRA findings for patients treated for PASTA were retrospectively reviewed. The patients were divided into two groups: conservative treatment and surgical repair...

We performed a pre-dissection computational fluid analysis of an ascending aortic aneurysm associated with unicuspid aortic valve. The analysis showed an abnormal helical flow pattern inside the aneurysm and an increased wall stress on the right postero-lateral wall of the ascending aorta. These values were largely higher than the theoretical cut-off for aortic wall dissection, their topographic distribution followed the intimal tear site as subsequently diagnosed by computed tomography scan and confirmed during the operation for dissection repair...

UNLABELLED: Rotator cuff pathology can contribute to shoulder pain and may affect the performance of sport activities, work, and activities of daily living. The partial articular supraspinatus tendon avulsion (PASTA) lesion represents a very common type of rotator cuff pathology seen in rehabilitation. When conservative treatment fails, surgery is generally required. Success of recovery depends on several factors, including: repair techniques, healing process related to timing, rehabilitation programs, and patient compliance with home exercises...
