Background: All-inside arthroscopic meniscal repairs are favored by most clinicians because of their lower complication rate and decreased morbidity compared with inside-out techniques. Until now, only 1000 cycles have been used for biomechanical testing. Hypothesis: All-inside meniscal repairs will show inferior biomechanical response to cyclic...

Reviewing the different meniscal repair devices and sutures with their respective biomechanical properties. Methods For this meta-analysis, we conducted a systematic online search using PubMed, EMBASE, CCTR, and CINAHL using the se...

Shoulder dislocation and subsequent anterior instability is a common problem in young athletes. The arthroscopic Bankart repair was originally described by Morgan et al. in 1987. The procedure has benefited from many technical advancements over the past 25 years and currently remains the most commonly utilized procedure in the treatment of anterior...

The ideal treatment for Achilles tendon ruptures is still unknown. Biomechanical were correlated to radiological and clinical parameters to study outcomes. In this retrospective, assessor-blinded multi-centre cohort study, 52 patients with unilateral Achilles tendon rupture were assessed, each at least 3 years after injury. Patients underwent open...

Growth factors such as the use of platelet-rich plasma-containing growth factors, e.g., IL-1 and IL-6 or TNF-alpha, have been extensively studied but their clinical benefits could not be found. However, currently there are upcoming studies on loading growth factors on matrices with promising results in animal models. To date, the easiest and most c...

Background: Previous biomechanical studies used single-pull destructive tests in line with the anchor and are limited by a great variability of bone density of cadaver samples. To overcome these limitations, a more physiological test setting was provided using titanium, bioresorbable, and all-suture anchors. Methods: In this controlled laborator...

Purpose Suprapectoral tenodesis is a frequently used technique for treating pathologies of the long head of the biceps brachii (LHBB) tendon. However, so far, no Gold Standard treatment exist. Hence, the arthroscopic LassoLoop360 (LL360) technique is introduced aiming to provide secure fixation and improved biomechanical properties. It was hypothes...

Achilles tendon disorders are most common in individuals who participate in endurance sports that involve repetitive loading of the foot. The increasing incidence is correlated with an expanding participation of the population in recreational and competitive sports and is therefore one of the more common disorders seen in sports medicine. In the fo...

Foot and ankle injuries are among the most common injuries in Martial Arts and account for a major part of loss of sports. Two factors are of utmost importance in dealing with foot and ankle injuries in contact combat sports. Firstly, injury prevention should already inhibit such injuries. Here, proprioceptive training is essential. Secondly, refer...

Glenohumeral arthritis typically affects patients after the sixth decade of life; however younger patients can also be afflicted.

It has been suggested that platelet-rich plasma (PRP) improves healing after arthroscopic rotator cuff repair. The current literature provides ample but inconsistent data on this topic. To systematically review the current in vivo evidence for the use of platelet concentrates (PRP) in the arthroscopic treatment of rotator cuff tears to assess effec...

Anterior glenoid bone defects are a frequent cause of shoulder instability and are considered to be one of the major causes of recurrence after shoulder stabilization. Proper early recognition of glenoid bone injury in the setting of recurrent instability will assist in making safe and successful decision making, particularly in the athletic patien...

Rotator cuff repairs have a high failure rate proportional to the tear size. Various techniques have been described to improve the repair strength and failure rate. The described surgical technique uses a biodegradable subacromial balloon-shaped spacer (InSpace; OrthoSpace, Caesarea, Israel) that is implanted arthroscopically to protect our tendon...

The evaluation of the glenohumeral joint laxity requires the estimate of the displacements of the humeral head center (HHC) with respect to the glenoid. To the authors' knowledge, several studies have been conducted to estimate HHC translations in vivo but data under anterior loading conditions has not been collected yet. Aim of this study was to d...

Sixteen patients were practicing competitive sports and...

Pain in the posterior area of the shoulder can be caused by pathologies of the suprascapular nerve. Pain may be due to neural entrapment while the nerve is passing through the suprascapular notch. A tear of the rotator cuff may cause traction, resulting in shoulder pain. This might be one of the reasons for persisting pain after successful rotator...

SUMMARY The understanding of the mechanism underlying glenohumeral joint stability is a key issue in orthopaedic surgery. The development of a non-invasive methodology to assess in vivo glenohumeral joint translation, when selected loads are applied, would contribute to the advancement of the state of art. Seven patients were acquired using a horiz...

The shoulder has the greatest range of motion of any joint in the human body. This is due, in part, to the complex interplay between the glenohumeral (GH) joint and the scapulothoracic (ST) articulation. Currently, our ability to study shoulder kinematics is limited, because existing models isolate the GH joint and rely on manual manipulation to cr...

Background: Controversy continues over the impact of re-excision (RE) on local recurrence (LR) in patients with invasive breast cancer. Patients and Methods: We investigated factors which could effect RE rates in patients undergoing breast-conserving or oncoplastic surgery. Between 2000 and 2003, 489 patients with stage pT1-pT2 or pN0/1 tumors were...

Rotator cuff pathology can contribute to shoulder pain, weakness, and limitations to both activities and work. Surgical repair via open or arthroscopic techniques is associated with improved function and patient satisfaction. Success of repair depends on several factors that include patient age, tear size, type of fixation, smoking status, and comp...

Dr. med. Claudio Rosso vom Universitätsspital Basel hatte die „dankbare“ Aufgabe, das exzentrische Training als Therapiemodalität zu verteidigen. Dieses hat sich bei der MidportionTendinopathie in randomisierten kontrollierten Studien (Level of Evidence Ib) als hervorragendes und kostengünstigstes Therapeutikum herausgestellt. Rosso konnte auch auf...

Tendons ruptures recover slower than fractures. Generally, early functional rehabilitation is associated with shorter hospital stay, lower complication rates and higher patient satisfaction. In order to support optimum healing without elongation or even rerupture, the operated tendon should be subjected to limited weight-bearing in an orthosis for...

Achilles tendon (AT) tendinopathies and ruptures are the most common diagnoses in AT disorders. Eccentric training is an established gold standard in the treatment of Achilles tendinopathies (LoE 1). Equally effective are doppler-ultrasound guided operations and sclerosing therapies as well as insoles in combination with physiotherapy (LoE 1). Curr...

All-inside meniscal repairs are performed with increasing frequency because of the availability of newly developed devices. A comparison of their biomechanical characteristics may aid physicians in selecting a method of meniscal repair. All-inside meniscal repairs will be superior to their inside-out controls in response to cyclic loading and load-...

Mechanical testing has been regarded as the gold standard to investigate the effects of pathologies on the structure-function properties of the skeleton. Tensile properties of cancellous and cortical bone have been reported previously; however, no relationships describing these properties for rat bone as a function of volumetric bone mineral densit...
