Articular cartilage damage is very common in clinical practices. Due to the low self-healing abilities of articular cartilage, the repair strategies for articular cartilage such as arthroscopic lavage and debridement,osteaochondral or chondrocytes transplantation, tissue engineering and hydrogel based artificial cartilage materials are the primary technologies of repairing articular cartilage defect. In this paper,the main repair strategies for the articular cartilage damage and the advantages or disadvantages of each repair technology are summarized. The arthroscopic lavage and debridement is successful in treating the early stage of osteoarthritis. Osteochondral and chondrocytes transplantation are beneficial to treat small full thickness defects. The technology of tissue engineering becomes a new method to heal articular cartilage damage, but the major problem is the absence of bonding strength between the implants and natural defect surfaces. Hydrogel based artificial cartilage possesses similar bio-mechanical and bio-tribological performances to that of natural articular cartilage. However, both bioactivity and interfacial bonding strength between the implant and natural cartilage could be further improved. How to simultaneously optimize the mechanical and bioactive as well as biotribological properties of hydrogel based materials is a focus problem concerned.

Knee osteoarthritis (OA) is a common and debilitating disorder marked by joint degradation, inflammation, and persistent pain. This study examined the possible therapeutic effects of curcumin and vitamin D on OA progression and pain in a rat knee OA model by anterior cruciate ligament transection and meniscectomy (ACLT + MMx). Male Wistar rats were categorized into five groups: control, curcumin-treated (100 mg/kg/day), vitamin D-treated (25 µg/kg/day), a combination of vitamin D and curcumin, and sham-operated.

After open-wedge high tibial osteotomy (OWHTO), the patella is displaced distally, causing patellofemoral joint degeneration. The objective of this study was to ascertain whether the combination of OWHTO and lateral retinacular release (LRR) can prevent articular cartilage degeneration of the patellofemoral joint using magnetic resonance imaging T2 mapping. This study included 37 patients (37 knees) who underwent OWHTO alone (OWHTO group) and 37 patients (37 knees) who underwent OWHTO with LRR (OWHTO + LRR group) with a correction angle of <10° for varus knee osteoarthritis.

Osteoarthritis (OA) is a chronic disease characterized by cartilage degradation, leading to bone friction, inflammation, stiffness, pain, and reduced mobility. This study investigates the therapeutic effects of porcine-derived chondroitin sulfate sodium (CS) on OA symptoms at both cellular and animal levels. study, HTB-94 chondrocytes were treated with inflammatory stimuli and CS (10, 50, 100, and 200 μg/mL) to assess the release of inflammatory mediators and the expression of genes and proteins related to cartilage synthesis and degradation.

Cartilage repair remains a critical challenge in orthopaedic medicine due to the tissue's limited self-healing ability, contributing to degenerative joint conditions such as osteoarthritis (OA). In response, regenerative medicine has developed advanced therapeutic strategies, including cell-based therapies, gene editing, and bioengineered scaffolds, to promote cartilage regeneration and restore joint function. This narrative review aims to explore the latest developments in cartilage repair techniques, focusing on mesenchymal stem cell (MSC) therapy, gene-based interventions, and biomaterial innovations.

Background: Knee osteoarthritis (KOA) is a prevalent degenerative joint disease. The primary pathological manifestations of KOA include articular cartilage degeneration, joint space narrowing, and osteophyte formation, leading to a spectrum of symptoms, including joint pain, stiffness, reduced mobility, diminished muscle strength, and severe disability. We aimed to utilize a meta-analysis to evaluate the efficacy of isokinetic muscle strengthening training (IMST) as a rehabilitation treatment for KOA in lowland areas.
