Summary: This study aimed to clarify the relationship between chronic preoperative opioids and complications following rotator cuff repair. Patients with prolonged preoperative opioid prescriptions had increased revision rates within both 6 months and 1 year post-surgery, with higher rates of preoperative NSAID use and tobacco use, indicating independent risk factors for revision.

Summary: This study investigates the transcriptional changes in the muscle after rotator cuff repair and identifies the timeline of these changes. The findings show that there are metabolic and energetic changes at 1 week post-repair, oxidative stress and mRNA stability changes at 2 weeks post-repair, increased adipogenesis at 4 weeks post-repair, and a low transcriptional steady state or a dysregulated stress response at 8 weeks post-repair. These results contribute to a better understanding of the biological mechanisms involved in rotator cuff repair.

Summary: This study analyzed transcriptional changes in rabbit supraspinatus muscle tissue at different time points post-tenotomy, revealing unique patterns of gene expression with the greatest changes observed at 1 week and a resurgence at 16 weeks. The findings provide insights into the biological mechanisms of chronic muscle degeneration after rotator cuff tears.

Summary: In this study, hydroxyapatite-incorporated polylactic acid (PLLA) aligned nanofibrous membranes were fabricated using electrospinning as a low-cost sustainable rotator cuff patch. The results showed that the nanofibrous membrane had good cell compatibility and the ability to induce bone formation, promoting tendon-bone healing.

Summary: The creation of pain as the fifth vital sign in 2001 led to a significant increase in postoperative narcotic use, resulting in chronic opioid use associated with overdoses and deaths. Despite the adverse effects, the persistent problem of opioid usage in orthopaedic surgery requires targeted training and efforts to address.

Summary: This study aimed to identify factors that reduce operative time and investigate the feasibility of performing arthroscopic rotator cuff repairs in under 5 minutes. The researchers found that using undersurface repair technique, reducing surgical anchors, smaller tear size, increased surgeon and assistant case number, performing repairs in a private hospital, and female sex were associated with faster operative times. They also successfully captured a <5-min repair.

Summary: The study found no significant advantages in strength, pennation angle, or muscle thickness in the dominant arm of healthy professional baseball pitchers. There was a positive correlation between infraspinatus muscle thickness and ER strength, while soft tissue GIRD had a moderate negative correlation with bilateral differences in the teres minor deep pennation angle.

Summary: This study aimed to determine the factors that affect radiographic severity in massive rotator cuff tears using multivariate analyses. The results showed that infraspinatus tear and long head of biceps tendon rupture were associated with superior migration of humeral head, while superior subscapularis tear and long head of biceps tendon rupture, as well as female sex, were associated with narrowing of the glenohumeral joint and humeral head collapse. These findings provide valuable information for understanding and managing massive rotator cuff tears.

Summary: This study characterized the progression of muscle and fat changes over time after the repair of a chronic rotator cuff tear in a rabbit model. The results showed that atrophy and muscle degeneration peaked around 2 weeks after repair, with no significant regeneration observed. Fat accumulation and fibrosis were increased at all time points compared to the contralateral side.

Summary: Open transosseous rotator cuff repair was the standard surgical technique, but the advent of arthroscopic and suture anchor technology shifted the paradigm. However, the use of suture anchors has drawbacks, such as cost and complications. Recently, new arthroscopic techniques have allowed for a return to transosseous repair without the need for suture anchors. This article reviews the literature surrounding arthroscopic transosseous rotator cuff repair from historical, biomechanical, clinical, and economic perspectives.

Summary: This study utilized MALDI-MSI technology to spatially profile the metabolism of shoulder muscle tissues, revealing significant metabolic differences between degenerated and intact regions. The identified metabolic signatures can provide new insights for developing personalized treatments for chronic shoulder muscles degeneration.

Summary: The study found that there were no significant differences in patient-reported outcomes between men and women undergoing rotator cuff surgery. While women were more likely to have dominant-arm surgery and had smaller rotator cuff tears than men, both groups reported high levels of satisfaction.

Summary: This study evaluated the role of CCR2 in tendon healing after rotator cuff repair. The results showed that CCR2KO may improve tendon biomechanical properties by reducing macrophage infiltration and/or suppressing inflammatory mediator pathways.

Summary: This study utilized multiomic approaches to investigate the pathological changes in Duchenne muscular dystrophy at the transcriptome, proteome, metabolome, and lipidome levels. Despite gross pathological changes in muscles of mdx/mTR mice, there were no differences in muscle fiber contractility compared to wild type mice. There was a moderate agreement between the proteome and transcriptome but also significant differences, with notable changes in markers of muscle metabolism observed in dystrophic muscles.

Summary: This study investigates the competing spatial demands of brain and masticatory muscle growth within hypermuscular myostatin-deficient mouse model and computational simulations, exploring the network linking single genes to multiple phenotypic outcomes. Findings reveal different muscle and brain volume changes in myostatin-deficient mice at different growth stages, and simulations show skeletal morphological changes associated with muscle expansion and endocranial expansion.

Summary: This study found that Ca2+ signaling through Ca(V)1.2 voltage-gated Ca2+ channel plays a role in tendon formation. Ca(V)1.2 is highly expressed in developing tendons but downregulated in adult homeostasis. Mutant tendons with increased Ca2+ signaling display hypertrophic characteristics, increased collagen fibrillogenesis, and alterations in ECM proteins and growth factors.

Summary: This exploratory study aimed to investigate the relationship between biomarkers of cartilage turnover and inflammation and specific shoulder lesions in patients with shoulder instability. The findings suggest that inflammatory biomarkers were not associated with specific shoulder lesions, while biomarkers of cartilage turnover were only elevated in Hill-Sachs lesions.
