We performed a systematic review of the literature to determine
whether earlier surgical repair of acute rotator cuff tear (ARCT)
leads to superior post-operative clinical outcomes. The MEDLINE, Embase, CINAHL, Web of Science, Cochrane Libraries,
controlled-trials.com and clinicaltrials.gov databases were searched
using the terms: ‘rotator cuff’, or ‘supraspinatus’, or ‘infraspinatus’,
or ‘teres minor’, or ‘subscapularis’ AND ‘surgery’ or ‘repair’.
This gave a total of 15 833 articles. After deletion of duplicates
and the review of abstracts and full texts by two independent assessors,
15 studies reporting time to surgery for ARCT repair were included.
Studies were grouped based on time to surgery <
3 months (group
A, seven studies), or >
3 months (group B, eight studies). Weighted
means were calculated and compared using Student’s Aims
Methods
Achilles tendon re-rupture (ATRR) poses a significant risk of postoperative complication, even after a successful initial surgical repair. This study aimed to identify risk factors associated with Achilles tendon re-rupture following operative fixation. This retrospective cohort study analyzed a total of 43,287 patients from national health claims data spanning 2008 to 2018, focusing on patients who underwent surgical treatment for primary Achilles tendon rupture. Short-term ATRR was defined as cases that required revision surgery occurring between six weeks and one year after the initial surgical repair, while omitting cases with simultaneous infection or skin necrosis. Variables such as age, sex, the presence of Achilles tendinopathy, and comorbidities were systematically collected for the analysis. We employed multivariate stepwise logistic regression to identify potential risk factors associated with short-term ATRR.Aims
Methods
Tendinopathy is a debilitating musculoskeletal
condition which can cause significant pain and lead to complete rupture
of the tendon, which often requires surgical repair. Due in part
to the large spectrum of tendon pathologies, these disorders continue
to be a clinical challenge. Animal models are often used in this
field of research as they offer an attractive framework to examine
the cascade of processes that occur throughout both tendon pathology and
repair. This review discusses the structural, mechanical, and biological
changes that occur throughout tendon pathology in animal models,
as well as strategies for the improvement of tendon healing. Cite this article:
Rotator cuff tears are among the most frequent upper extremity injuries. Current treatment strategies do not address the poor quality of the muscle and tendon following chronic rotator cuff tears. Hypoxia-inducible factor-1 alpha (HIF-1α) is a transcription factor that activates many genes that are important in skeletal muscle regeneration. HIF-1α is inhibited under normal physiological conditions by the HIF prolyl 4-hydroxylases (PHDs). In this study, we used a pharmacological PHD inhibitor, GSK1120360A, to enhance the activity of HIF-1α following the repair of a chronic cuff tear, and measured muscle fibre contractility, fibrosis, gene expression, and enthesis mechanics. Chronic supraspinatus tears were induced in adult rats, and repaired 28 days later. Rats received 0 mg/kg, 3 mg/kg, or 10 mg/kg GSK1120360A daily. Collagen content, contractility, fibre type distribution and size, the expression of genes involved in fibrosis, lipid accumulation, atrophy and inflammation, and the mechanical properties of the enthesis were then assessed two weeks following surgical repair.Objectives
