Frontal plane humeral elevation effects on the pullout strength of suture anchors used in rotator cuff repair The rotator cuff offers the stabilizing forces necessary for fine arm movement. The most common injury to the rotator cuff is the partial or full thickness tear of the supraspinatus tendon, which attaches the humerus to the scapula on the superior side, due to an acute or chronic injury...

BACKGROUND AND PURPOSE Few authors have considered the outcome after acute traumatic rotator cuff tears in previously asymptomatic patients. We investigated whether delay of surgery, age at repair, and the number of cuff tendons involved affect the structural and clinical outcome. PATIENTS AND METHODS 42 patients with pseudoparalysis after trauma and no previous history of shoulder symptoms w...

BACKGROUND Pathology of the long head of the biceps tendon (LHB) is commonly associated with rotator cuff tears (RCTs). Superior labral anterior-posterior (SLAP) lesions can also occur with RCTs. The purpose of this study was to include SLAP lesions as part of LHB pathology in surgical cases of RCT and define the role of SLAP lesions in RCTs. METHODS We retrospectively evaluated clinical data...

Characteristics of the spreads of platelet-rich plasma (PRP) are not widely known despite commonly use. This study aims to evaluate whether PRP stays within the injected area by using ultrasonography, to improve understanding of the spreads of intratendinous injected PRP. Thirty-nine patients (15 males, 24 females; mean age, 49.3 years), who had symptoms on their elbows (> 6 months) and diagnos...

INTRODUCTION: Previous testing of various collagen cross-linking agents showed potential to increase stiffness and failure behavior as well as reduce hysteresis and creep behavior in rat tail tendon fascicles [1]. Based on these results, we hypothesized that exogenous collagen cross-linking might be a candidate for reinforcing injured or healing tendons or to halt progression of tendon tears. T...

Introduction: The clinical outcomes of rotator cuff repair vary among patients and are affected by multiple factors including chronic inflammation. Although inflamed synovium is a common clinical observation at the time of surgery, the role of this inflammation plays on clinical outcomes is not well elucidated. Several recent studies have shown that there is elevation of pro-inflammatory cytoki...

Abstract Background Supraspinatus tendon is a part of the rotator cuff shoulder, partial or full-thickness tear can affect secondary to trauma repeated microtrauma. The aim present study evaluate efficacy platelet-rich plasma (PRP) injection in comparison physical therapy for treatment chronic supraspinatus tears. Results At beginning study, there were no significant differences between both gr...

We reported previously the formation of microtears in an in vivo loaded Flexor Digitorum Profundus (FDP) rabbit tendon with a repetition rate of 60 repetitions per minute and a peak force of 15% of maximum peak tetanic force for 80 cumulative hours. Tear area as a percent of tendon area, tear density (tears/mm(2)), and mean tear size (microm(2)) were higher in tendons from the loaded limb compa...

The Achilles tendon is the strongest tendon in the body, which is commonly ruptured in male athletes. Bilateral rupture of the Achilles tendon is a rare condition with very few reported cases in the literature. It poses a challenge in management, and hence, we report a case with traumatic bilateral Achilles tendon rupture in a young male patient and its management. One side was treated conserva...

INTRODUCTION Degenerative rotator cuff tears are a common problem, affecting greater than 30% of the general population [1]. Rotator cuff tears most commonly occur in the supraspinatus tendon near the insertion site [2]. There is a high failure rate of rotator cuff tear repairs, and this failure typically occurs at the tendon-suture interface [3]. By determining localized differences in rotator...
