Background: The self-repair ability after meniscal tears is poor, leading to the development of posttraumatic osteoarthritis. Promoting the repair of meniscal injuries remains a great challenge, especially in the avascular region.

Hypothesis: Local delivery of skeletal stem cell (SSC)-derived exosomes (SSC-Exos) would promote meniscal healing and prevent secondary osteoarthritis progression.

Osteoarthritis (OA) is a degenerative joint disease characterized by progressive erosion of the articular cartilage and inflammation. Mesenchymal stem cells' (MSCs) transplantation in OA treatment is emerging, but its clinical application is still limited by the low efficiency in oriented differentiation. In our study, to improve the therapeutic efficiencies of MSCs in OA treatment by carbonic anhydrase IX (CA9) siRNA (siCA9)-based inflammation regulation and Kartogenin (KGN)-based chondrogenic differentiation, the combination strategy of MSCs and the nanomedicine codelivering KGN and siCA9 (AHK-CaP/siCA9 NPs) was used.

The meniscus is a fibrocartilaginous tissue of the knee joint that plays an important role in load transmission, shock absorption, joint stability maintenance, and contact stress reduction. Mild meniscal injuries can be treated with simple sutures, whereas severe injuries inevitably require meniscectomy. Meniscectomy destroys the mechanical microenvironment of the knee joint, leading to cartilage degeneration and osteoarthritis.

Background: Tibiofibular syndesmosis (TFS) widening sometimes is not evident on radiography but can be found under arthroscopy in chronic lateral ankle instability (CLAI). This study aimed to evaluate the effect of TFS widening severity on clinical outcomes and return to activities after isolated Broström operation in CLAI patients and to propose an indication for its surgical intervention.

Methods: A total of 118 CLAI patients undergoing diagnostic ankle arthroscopy and open Broström-Gould operation were included.

Osteoarthritis (OA) is a progressive joint disease characterized by inflammation and cartilage destruction, and its progression is closely related to imbalances in the M1/M2 synovial macrophages. A two-pronged strategy for the regulation of intracellular/extracellular nitric oxide (NO) and hydrogen protons for reprogramming M1/M2 synovial macrophages is proposed. The combination of carbonic anhydrase IX (CA9) siRNA and NO scavenger in "two-in-one" nanocarriers (NAHA-CaP/siRNA nanoparticles) is developed for progressive OA therapy by scavenging NO and inhibiting CA9 expression in synovial macrophages.

Purpose: To compare the return-to-activity and long-term clinical outcomes between anatomic lateral ligament reconstruction using the autologous gracilis tendon and modified Broström-Gould (MBG) procedure in chronic lateral ankle instability (CLAI). It was hypothesised that there was no difference between the two techniques.

Methods: From 2013 to 2018, 30 CLAI patients with grade III joint instability confirmed by anterior drawer test underwent anatomic reconstruction of lateral ankle ligament with the autologous gracilis tendon (reconstruction group) in our institute.

Purpose: This study aims to evaluate the mid- to long-term outcome of concurrent arthroscopic treatment of osteochondral lesion (OCL) and open anatomical repair of lateral ankle ligaments for severe acute ankle sprain patients and compare them to the outcome of those without OCL.

Methods: A total of 166 patients with grade III acute lateral ankle ligament injuries underwent concurrent ankle arthroscopy and open anatomic ligament repair. Forty-three patients (group A) with OCL underwent arthroscopic treatment followed by open ligament repair.

Article Synopsis
  • - The study investigates the role of long non-coding RNAs (lncRNAs) in the aging process of the meniscus, identifying 1608 differentially expressed (DE) lncRNAs and 1809 DE mRNAs through microarray analysis and confirming results with qRT-PCR.
  • - Key findings reveal that DE mRNAs are involved in critical signaling pathways (like TGF-beta and Wnt), with specific upregulations of TNFRSF11B and BMP2 in the aging group.
  • - Four lncRNAs (AC124312.5, HCG11, POC1B-AS1, and AP001011.1) were linked to meniscus degradation, with functional analyses suggesting they interact with various

Cartilage injury of the knee joint is very common. Due to the limited self-healing ability of articular cartilage, osteoarthritis is very likely to occur if left untreated. Bone marrow mesenchymal stem cells (BMMSCs) are widely used in the study of cartilage injury due to their low immunity and good amplification ability, but they still have disadvantages, such as heterogeneous undifferentiated cells.

microRNA (miR)-141-3p has context-dependent effects on tumor progression. In this study, we attempted to explore the expression and function of miR-141-3p in cervical cancer. We found that miR-141-3p expression was significantly increased in cervical cancer specimens relative to normal cervical tissues.
