Background/hypothesis Shoulder pain in elite swimmers is common, and its pathogenesis uncertain. Hypothesis/study design The authors used a crosssectional study to test Jobe’s hypothesis that repetitive forceful swimming leads shoulder laxity, which turn impingement pain. Methods Eighty young (13–25 years of age) completed questionnaires on their training, function. They were given standardised clinical examination, tested for glenohumeral joint laxity using non-invasive electronic...
Background: Noninsertional Achilles tendinopathy is a degenerative overuse disorder. No method has been universally successful in treating this condition. Topically applied nitric oxide shown, animal models, to be effective for the treatment of fractures and cutaneous wounds through mechanisms that may include stimulation collagen synthesis fibroblasts. The goal present study was determine if topical glyceryl trinitrate improves clinical outcome measures patients with tendinopathy. Methods:...
Background: Extensor tendinosis (“tennis elbow”) is a degenerative overuse tendinopathy of the wrist extensors at their attachment to lateral humeral epicondyle. No treatment has been universally successful. Topical application nitric oxide used effectively treat fractures and cutaneous wounds in animal models, presumably by stimulation collagen synthesis fibroblasts. Purpose: To determine whether topical can improve outcome patients with extensor tendinosis. Study Design: Prospective,...
ObjectiveThe optimal anterolateral procedure to control rotational laxity of the knee is still unknown. The objective was compare ability five procedures performed in combination with anterior cruciate ligament reconstruction (ACLR) restore native kinematics setting a deficient (ACL) and structures.MethodsA controlled laboratory study using 10 fresh-frozen cadaveric whole lower limbs intact iliotibial band. Kinematics from 0° 90° flexion were recorded motion analysis three-dimensional (3D)...
Background Topical glyceryl trinitrate therapy has previously demonstrated short-term pain reduction in patients with supraspinatus tendinopathy. Hypothesis improves outcome measures Study Design Randomized controlled clinical trial; Level of evidence, 1. Methods Fifty-three (57 shoulders) were recruited, and the authors completed a prospective, randomized, double-blinded, placebo-controlled trial continuous topical treatment (1.25 mg/24-h trinitrate). Results The group had significantly...
Abstract Objective To evaluate histologic, immunohistochemical, and molecular changes in tendon induced by altered strain a large‐animal model. Methods A full‐thickness partial‐width laceration of the infraspinatus was created 5 sheep, while sham‐operated sheep were used as controls. Sheep killed after 4 weeks, differentially stressed regions (tensile or near bone attachment from overstressed stress‐deprived halves) evaluated for histopathology, proteoglycan (PG) accumulation,...
A muscle's moment arm represents its mechanical advantage and indicates role in joint actuation rotational stability. The objective of this study was to use an ex-vivo simulator map the arms eight major shoulder muscles across a continuous range motion. three-dimensional for deltoid (anterior, lateral, posterior), subscapularis (inferior superior), supraspinatus, infraspinatus, teres minor were measured specimens (57 ± 6 years) using tendon excursion method. anterior had significantly larger...
This study investigates the accuracy and reliability of a novel handheld indentation system designed to ascertain dynamic biomechanical properties articular cartilage.
Tendon disorders with a chronic nature, including the rotator cuff, are extremely common, and represent major clinical problem. Mechanical overload has been proposed as an important etiologic factor in tendinopathies. Nitric oxide (NO), free radical produced by nitric synthases (NOSs), is potent regulator stimulator of biological processes tendon degeneration healing. It also involved response to mechanical stimuli different tissues. In animal model acutely injured healing temporal...
To determine the interobserver and intraobserver reliability of interpretation MRIs for supraspinatus tendinosis.In trial, 52 athletes' shoulders were observed by 3 observers on one occasion within a 2-month period. All images read most experienced musculoskeletal radiologist different occasions separate days without access to previous readings trial. Supraspinatus tendinosis was graded using modified 4-point scale from grades 0 grade 3.The grading MRI-determined reliable, having an...
An investigation of mechanical destabilization the lumbar ovine intervertebral disc (IVD) inducing IVD degeneration (IVDD) as determined by multiparameter outcome measures (magnetic resonance imaging [MRI], composition, biomechanical testing, gene profiling, immunohistochemistry, and immunoblotting).To assess effect on matrix protein metalloproteinase expression to investigate pathophysiological mechanisms IVDD.Several earlier studies have used annular transection induce IVDD in sheep, but...
ObjectivesGiven the common occurrence of residual laxity and re-injury post anterior cruciate ligament reconstruction (ACLR), additional anterolateral procedures are increasingly used in combination with an ACLR. Despite perception that there is a risk over-constraining lateral tibiofemoral (LTF) compartment, potentially leading to osteoarthritis, assessment on their effect intra-articular compartment pressures still lacking. Our objective was therefore, through pilot biomechanical study,...
Background: Preoperative quantification of bone loss has a significant effect on surgical decision making and patient outcomes. Various measurement techniques for calculating glenoid have been proposed in the literature. To date, no studies directly compared to determine which technique, if any, is most reliable. Purpose/Hypothesis: identify consistent accurate measuring anterior glenohumeral instability. Our hypothesis was that linear would lower consistency accuracy than surface area...
