Summary: This study investigated the clinical outcomes of preserving or excising the infrapatellar fat pad (IPFP) during anterior cruciate ligament reconstruction (ACLR). The results showed that preserving IPFP led to more significant improvements in anterior knee pain and knee joint function compared to excising IPFP. Surgeons should avoid excising IPFP as much as possible to ensure the effectiveness of ACLR.

Summary: In recent years, there has been increasing research interest in the infrapatellar fat pad (IFP). It is believed to play a role in the development and progression of knee osteoarthritis (OA) through its interactions with the synovium, articular cartilage, and subchondral bone. While IFP is (partially) resected in most total knee arthroplasties (TKA), there is currently no clear guideline in favor of or against this practice.

Summary: This study evaluated the effect of exosomes derived from infrapatellar fat pad (IPFP) mesenchymal stromal cells (MSCs) on tendon-bone healing and intra-articular graft remodeling after anterior cruciate ligament reconstruction (ACLR) in a rat model. The results demonstrated that IPFP MSC-derived exosomes accelerated tendon-bone healing and intra-articular graft remodeling, possibly through the immunomodulation of macrophage polarization.

Summary: This study analyzed the role of infrapatellar fat pad (IFP) and suprapatellar fat pad (SFP) in knee osteoarthritis (OA) using magnetic resonance (MR) imaging. The results showed differences in the characteristics of these tissues among different patient groups, supporting their importance in the pathology and progression of OA.

Summary: This study identified differences in the quantity and quality of CD14-positive cells in the infrapatellar fat pads and subcutaneous fat tissues of OA and RA patients. Patients treated with bDMARDs showed a higher ratio of CD14(++)CD80(+) cells/CD14(++)CD163(+) cells in the IFP, indicating localized inflammation. This suggests that adipose tissue-derived innate immune cells could be a potential target for new therapeutic strategies in inflammatory joint diseases.

Summary: The infrapatellar fat pad (IFP) plays an important role in knee osteoarthritis, with age affecting its tissue characteristics even in the absence of pathological conditions. Differences were observed between the young group and elderly group in terms of collagen III levels and adipocyte size. Additionally, aging was associated with a decrease in total collagen deposition in the IFP tissue.

Summary: Intra-articular injection of tropoelastin (TE) improves the adhesion, migration, and chondrogenic differentiation of mesenchymal stem cells (MSCs) and enhances matrix synthesis of osteoarthritic chondrocytes (OACs). In vitro experiments demonstrate that TE enhances MSCs adhesion through activation of specific pathways. In vivo experiments show that intra-articular injection of TE-MSCs suspension increases MSCs survival rate and improves histology scores of joint tissues.

Summary: The study investigates the role of infrapatellar fat pad (IPFP) in knee osteoarthritis (OA) progression and identifies dysregulated osteopontin (OPN) and integrin beta 3 signaling in OA specimens. The study demonstrates that IPFP-derived OPN plays a role in OA progression, including chondrocyte hypertrophy and IPFP fibrosis. An injectable nanogel, (RGD-)Nanogel/siRNA Cd61, is developed to target integrins and effectively alleviate cartilage degeneration and subchondral bone mass in OA mice.

Summary: This study demonstrated that Hesperetin (HPT) has chondroprotective and anti-inflammatory effects on chondrocytes through the AMPK signaling pathway, inhibiting TNF-alpha-induced cartilage degradation and promoting chondrocyte proliferation. RNA sequencing identified potential molecular targets, with 549 differentially expressed genes, and highlighted the importance of the AMPK pathway in mediating HPT's protective effects. Overall, HPT shows promise as a natural drug for osteoarthritis treatment.

Summary: Infrapatellar fat pad (IPFP) is associated with the progression of knee osteoarthritis (OA), as it secretes small extracellular vesicles (sEVs) that promote cartilage destruction and cellular senescence. The let-7b-5p and let-7c-5p in IPFP-sEVs directly decrease the negative regulator of senescence, lamin B receptor (LBR). This study uncovers the function and mechanism of IPFP-sEVs in the progression of OA, providing a potential strategy for OA therapy.

Summary: Cartilage damage is often difficult to repair, and current treatment strategies are inadequate. Autologous mesenchymal stem cells are considered a promising therapeutic approach for cartilage regeneration, as they possess robust cartilaginous production capacity and are easy to isolate and expand without causing morbidity.

Summary: Artificial sphincters (ASs) are used to replace the function of biological sphincters in cases of severe urinary and fecal incontinence and gastroesophageal reflux disease. However, commercial ASs currently have sub-optimal clinical outcomes due to device malfunction and side effects on biological tissues. It is important to investigate the interaction between biological tissues and ASs and develop innovative AS designs.

Summary: This study investigated the mechanism of gastro-oesophageal reflux disease (GERD) using computational models. It found that laparoscopic sleeve gastrectomy could induce de novo GERD and worsen pre-existing GERD. Variables such as the His-angle, antral dimension, and bolus viscosity were found to affect reflux increase.

Summary: The biomechanical response of bone tissues is crucial for understanding the functional response of dental implants, especially in cases of misfit. The interaction between surgical procedures and healing phases primarily depends on bone tissue response, which is influenced by specific loadings. This pilot study aims to define a method for biomechanical investigation and highlight the need to integrate clinical knowledge with biomechanical analysis to interpret osseointegration.

Summary: This study investigated the basal INSL5 plasma levels in morbidly obese subjects before and after laparoscopic sleeve gastrectomy. The results showed that obese subjects had elevated INSL5 levels before surgery, which were positively correlated with BMI, fat mass, and leptin levels. After surgery, INSL5 levels significantly decreased, and there was no expression of the INSL5 gene in human adipose tissue. These findings suggest that the reduction of INSL5 levels after bariatric surgery may contribute to appetite reduction.

Summary: Recent studies have found an association between thoracolumbar fascia thickness and reduced gliding in patients with lower back pain. This study aimed to measure and compare the thickness of thoracolumbar fascia in chronic non-specific lower back pain patients and healthy individuals using ultrasound imaging. The results showed that lower back pain patients had a loss of anisotropy in the thoracolumbar fascia, with a homogeneous increase in thickness and a loss of adaptability in the transverse direction.

Summary: In this study, the effects of sex steroids on the expression of inflammatory mediators in human-derived adipocytes were evaluated. The results showed that non-aromatizable androgen DHT and the aromatase inhibitor anastrozole in combination with testosterone significantly enhanced the expression of inflammatory cytokines induced by LPS. These results confirm the involvement of sex hormones in adipose tissue inflammation and suggest a specific role for non-aromatizable androgens as amplificatory sex hormones of the inflammatory response.

Summary: Spondyloarthritis (SpA) is a group of chronic inflammatory diseases affecting the axial and peripheral joints, tendons, and entheses. Inflammatory bowel disease (IBD) is strongly associated with SpA and has significant impacts on patients' quality of life. Effective treatment requires close collaboration between gastroenterologists and rheumatologists to identify and manage joint and intestinal manifestations, and current drug options for both conditions remain limited.

Summary: This study compared the clinical and radiographic outcomes of operative and non-operative treatment for acute displaced midshaft clavicle fractures (ADMCFs), and verified the effectiveness of the institutional treatment protocol. The results showed that conservative treatment had better clinical outcomes, while return to sports was longer in the surgical group. However, both groups achieved good mid-term clinical results without any signs of non-union.
