Articular cartilage injury is common in clinical in recent years, due to the trauma or bone disease. There are many methods for the repair of articular cartilage injury currently, but each has its limitations. With the development of nanotechnology and bionic-technology, the scaffold plays an important role with tissue engineering technique in the repair of articular cartilage injury, in which the composite materials are the hot direction of the research and development, the ful application of nanotechnology and bionic-technology prospect in the future.

Osteoarthritis (OA) is a common joint disease, which is mainly characterized by the degeneration of articular cartilage, inflammation of the synovial membrane of the joint, and changes in the surrounding bone tissue. With the increase of age and weight, the incidence of OA gradually increases, which seriously affects the quality of life of patients. The primary pharmacological treatments for OA include analgesics and non-steroidal anti-inflammatory drugs.

Background: It is known that open wedge high tibial osteotomy (OWHTO) may lead to progression of patellofemoral degeneration due to descent of the patellar height. However, the difference in patellofemoral joint (PFJ) loads with normal daily activity between uniplane and biplane osteotomies is unclear. The purpose of this study was to reveal the differences in PFJ biomechanics between uniplane and biplane OWHTO using finite element analysis (FEA).

Background: There is currently no definitive treatment for osteoarthritis. We examined the therapeutic effects and underlying mechanisms of platelet-rich plasma (PRP) and adipose-derived mesenchymal stem cells (ADSCs), individually or in combination, in a rat model of anterior cruciate ligament-induced degenerative osteoarthritis (OA) of the knee. This study seeks to advance clinical approaches to OA treatment.

Osteoarthritis (OA) is a multi-factorial degenerative joint disease with unclear pathogenesis. Conservative treatments, primarily aimed at pain relief, fail to halt disease progression. Metabolic syndrome has recently been implicated in OA pathogenesis, underscoring the need for novel therapeutic strategies.

Osteoarthritis (OA) is a degenerative joint disease accompanied with the loss of cartilage and consequent nociceptive symptoms. Normal articular cartilage maintains at aneural state. Neuron guidance factor Semaphorin 3A (Sema3A) is a membrane-associated secreted protein with chemorepulsive properties for axons.
