PURPOSE AND HYPOTHESIS: The aim of this study was to evaluate outcomes after acetabular labral reconstruction using the indirect head of the rectus femoris tendon. The study hypothesis stated that arthroscopic acetabular labral reconstruction may improve patient reported outcomes in patients with labral tears that were not amenable to repair. METHODS: Between 2009 and 2015, the senior author performed 31 acetabular labral reconstructions using the indirect head of the rectus femoris tendon...

BACKGROUND: Patellar tendon chronic ruptures are more debated to manage that acute injuries as the patella tends to retract proximally (after 2 weeks), and surrounding soft tissues may make the repair more complicate. PURPOSE: We propose a novel technique in which the patellar tendon is reconstructed using ipsilateral hamstring tendons. This surgical procedure implies to drill a single tunnel through the patella and another through the tibia to reduce the risk of bony breakage...

BACKGROUND: The intra-tendinous tear is a new pathology that is defined as a discontinuity of fibres situated entirely within the tendon. Prolotherapy involves injecting an irritant, such as hyperosmolar dextrose, to stimulate a tissue healing response and ultimately reduce pain. METHODS: 43 consecutive patients diagnosed with an intra-tendinous tear were included (27 males: 16 females, mean (SD) age 41 (11.3). Patients were injected with 0.4ml-1.5ml (mean 0.8ml) of 50% dextrose and 0...

BACKGROUND: Achillodynia is common and includes Achilles tendinopathy, partial Achilles tears and Achilles tendon ruptures. However, we believe an additional pathology should be considered for Achillodynia differentials - the intratendinous tear (ITT). METHODS: Examinations of 740 achillodynic patients in one specialist centre were reviewed. ITTs were defined as a clearly visualised echopoor area situated centrally and extending to, but not through the tendon periphery, with pain on palpation and no clinical findings consistent with Achilles rupture...

BACKGROUND: Mechanical factors are at the basis of any tendon healing process, being pressure an aspect able to positively influence it. For this reason transosseous rotator cuff repair represents the gold standard procedure for patients affected by a cuff tear, maximizing the tendon footprint contact area and reducing motion at the tendon to bone interface. METHODS: The Authors present an all arthroscopic suture bridge-like transosseous repair with the preparation of a single transosseous tunnel perfor med thanks to a precise dedicated instrument (Compasso®) and one implant (Elite-SPK®) with the use of only 3 suture wires...

Tendon disorders commonly cause hand and wrist disability and curtail the performance of work-related duties or routine tasks. Imaging is often needed for diagnosis, but it requires knowledge of the complex anatomic structures of the tendons of the hand and wrist as well as familiarity with related disorders. This review article aims to provide medical professionals with guidelines for the sonographic assessment of the tendons of hand and wrist and related disorders. Sonographic features of tendon disorders affecting the hand and wrist are described here, specifically: infectious tenosynovitis; tendon rupture or tearing; stenosing forms of tenosynovitis such as De Quervain disease and trigger finger; intersection syndrome; insertional tendinopathy; several forms of tendinous instability such as extensor carpi ulnaris instability, climber finger, and boxer knuckle; and tendinopathy in inflammatory rheumatic diseases...

OBJECTIVES: The aim was to assess the diagnostic performance of magnetic resonance arthrography (MRA) of the shoulder for the detection of "Fosbury flop" tears. METHODS: All patients undergoing arthroscopic rotator cuff repair were considered as potentially eligible for inclusion in this prospective case series. Preoperative MRAs were consecutively performed and compared with intraoperative findings being the gold standard control. Two experienced musculoskeletal radiologists, blinded to the arthroscopic findings, independently analyzed all MRAs for the presence of typical signs of Fosbury flop tears...

PURPOSE: In order to evaluate whether overuse has a significant role in rotator cuff tear (RCT) aetiology, we evaluated both shoulders of patients with old unilateral arm amputation expecting a higher rate of RC degeneration in the healthy side. METHODS: Nineteen males and six females (mean age: 57.3 ± 10.1) with an old (>20 years) unilateral arm amputation were submitted to an MRI of both shoulders. Tendon status and muscle tropism were evaluated according to Sugaya and Fuchs classifications, respectively; the acromion humeral distance was measured...

This Technical Note presents an arthroscopic technique to repair rotator cuff tears using a constant intra-articular (glenohumeral) portal for visualization. The smoothness of both the humeral head cartilage and the articular side of the rotator cuff offers a cleaner arthroscopic approach, while the absence of a subacromial bursa also reduces bleeding, turbidity, and the need for iterative soft tissue debridement. It also facilitates the recognition and repair of certain tear patterns. The intra-articular perspective allows the surgeon to visualize how stitches pierce the tissue in a desired and resistant area of the tendon...

Given the prevalence of anterior cruciate ligament (ACL) tears in young athletes, it is essential to elucidate and illustrate surgical interventions that return the most favorable outcomes. Although most ACL injuries are full-thickness tears, occasionally either the anteromedial (AM) or posterolateral (PL) bundle is torn in isolation, allowing consideration of an ACL reconstruction or augmentation. Because the ACL-deficient knee has been shown to exhibit less proprioceptive feedback, the preservation of the intact bundle may offer an inherent component of stability...

Irreducible shoulder dislocation is an uncommon event. When it does occur, blocks to reduction can include bone, labrum, rotator cuff musculature, or tendon. Concomitant rotator cuff tear at the time of initial dislocation is not an exclusive complication of anterior shoulder dislocation in the older population. Indeed, rotator cuff tear should not be excluded based solely on the patient's age. Rotator cuff interposition is not an uncommon complication after anterior dislocation of the shoulder. It should be suspected when there is incongruency of the joint and persistent subluxation on postreduction radiographs...

With the rise in subscapular tendon tears, most of them being partial that eventually end up in complete tears, we present our experience in the management of such tears using a cross shuttle loop technique. This technique incorporates the advantages of a single portal for anchor placement and repair, easy to use cross loops in limited working space, and familiar viewing.

Rotator cuff tears in young overhead sports athletes are rare. The pathomechanism causing rotator cuff tears in young overhead athletes is different from that in aged patients. The purpose of this study was to investigate rotator cuff tear characteristics in young overhead sports athletes to reveal the pathomechanism causing these injuries. This study included 25 overhead sports athletes less than 30 years old with atraumatic rotator cuff tears necessitating repair. Rotator cuff tear characteristics were evaluated intraoperatively, including rotator cuff tear shape and injured rotator cuff tendon...
