Osteoarthritis (OA) is a major clinical and scientific challenge. The degradation of articular cartilage in the joints is a common manifestation of painful arthritis. The regeneration of articular cartilage in OA is an unmet clinical need. The assembly of articular cartilage by tissue engineering toward complete regeneration is the goal of most scientists and surgeons. The key ingredients for regeneration are signals, stem cells, and scaffolds. This brief review focuses on the scaffold, with special emphasis on hydrogels and nanomaterials for the assembly of tissue-engineered cartilage, and ultimately leading to the total regeneration of articular cartilage in the joints.

Osteoarthritis (OA) is a globally prevalent degenerative joint disease. Recent studies highlight the role of ferroptosis in OA progression. Targeting ferroptosis regulation presents a promising therapeutic strategy for OA; however, current research primarily focuses on single targets associated with ferroptosis.

Background: Polydatin (PD), also known as tiger cane glycoside, is a natural compound extracted from the Japanese knotweed plant, which is often referred to as white resveratrol. It exhibits anti-inflammatory, antioxidant, and anti-apoptotic effects in the treatment of various diseases. However, the potential molecular mechanisms of PD in osteoarthritis have not been clearly elucidated.

Femoroacetabular impingement syndrome (FAIS) is a common condition of the hip that can cause significant damage to the joint, leading to degeneration and osteoarthritis. FAIS constitutes an abnormal and dynamic contact between the femoral head-neck junction and the acetabular rim, resulting from altered bone morphology at one or both sites. Repetitive trauma at the site of impingement generates progressive damage to the acetabular labrum, chondrolabral junction, and articular cartilage.

Due to its unique structure, articular cartilage has limited self-repair capacity. Microtissues are tiny tissue clusters that can mimic the function of target organs or tissues. Using cells alone for microtissue construction often results in the formation of necrotic cores.

Knee and hip osteoarthritis (OA) are two of the leading causes of disability globally. Knee OA is characterized by gradual degeneration of articular cartilage, leading to pain, stiffness, and functional limitations. Patients older than 50 years typically present with knee OA, but it can manifest earlier, particularly following traumatic knee injuries.
