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 evaluated the mid-term clinical and radiological outcomes of arthroscopic biceps-incorporating rotator cuff repair with partial release of the long head of the biceps tendon (LHBT) and footprint medialization. The results showed satisfactory improvements in pain scores, shoulder function scores, and range of motion. The tendon integrity and acromio-humeral interval were also preserved.

Summary: Minimally invasive surgery for humeral fractures may have cosmetic benefits, but postoperative malrotation could increase the risk of rotator cuff and cartilage degeneration. Animal experiments showed that the malrotated group had higher scores for cartilage and rotator cuff pathology, as well as disrupted collagen alignment.

Summary: Rotator cuff tear is a common shoulder problem that affects millions of people worldwide, especially the elderly and active athletes. Treatment options include conservative therapy, surgery, and biologics such as platelet-rich plasma, growth factors, stem cells, and exosomes, which are popular in laboratory research and clinical trials.

Summary: Cellular lipid accumulation is correlated with the MRI Goutallier grade, showing that partial-thickness rotator cuff tears are more similar to controls, while full-thickness tears have greater lipid content and smaller myofiber cross-sectional area.

Summary: The study compared the clinical and radiographic results of arthroscopic rotator cuff repair (ARCR) with biceps rerouting (BR) and conventional repair for semirigid, large-to-massive rotator cuff tear. It found that ARCR + BR had a significantly lower retear rate compared to conventional treatment, and identified partial tearing involving more than 50% of the long head of the biceps tendon and wide/thin tendon morphology as significant risk factors for postoperative retear.

Summary: The combination of growth factors (GFs) promoted proliferation and differentiation of human tenocytes in vitro, and improved the histological appearance and mechanical properties of the repaired tendon-bone interface in vivo.

Summary: The limited regenerative capacity of the tendon-bone enthesis after surgical repair presents a challenge to achieving desired clinical outcomes. Biologic augmentation methods show potential for improving the integrity of the enthesis, but there is currently no reliable method that consistently leads to clinical improvement.

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: The study on complex and revision rotator cuff repairs with dermal allograft augmentation in 35 patients showed that double-row arthroscopic repair led to improved functional outcomes. Approximately half of patients experienced a failure of healing, which was associated with poorer functional results.

Summary: The study showed a significant association between sex hormone deficiency and rotator cuff repair (RCR). Estrogen deficiency in females and testosterone deficiency in males were found to increase the risk of RCR. Future prospective studies are needed to further understand the connection between rotator cuff disease and sex hormones.

Summary: Ultrasonographic imaging has been widely used in diagnosing rotator cuff tears. This study aimed to determine if sutures migrate through the tendon during the postoperative healing period, the time point at which it happens, and how tendon quality affects suture migration. The results suggest that sutures migrating to the middle of the tendon is a normal phenomenon during postoperative healing, observed through ultrasonography.

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: Genetic factors may influence the age at diagnosis for atraumatic rotator cuff tear patients. Specific single nucleotide polymorphisms (SNPs) are associated with younger diagnosis age, but not with bilateral tear prevalence or tear size. Further research is needed to determine if genetic markers can be used alongside patient characteristics to identify optimal surgical repair candidates.

Summary: This review examines the effects of culture and material properties distinct from traditional planar TCP surfaces on MSC proliferation, surface marker expression, and therapeutic potency. Different properties such as alternative culture formats and culture substrate stiffness can lead to greater cell expansion and improvements in specific therapeutic functionalities, highlighting the importance of culture materials in enhancing clinical-scale manufacture of MSC products.
