Abstract
Articular cartilage injury is a prevalent clinical condition resulting from trauma, tumors, infection, osteoarthritis, and other factors. The intrinsic lack of blood vessels, nerves, and lymphatic vessels within cartilage tissue severely limits its self-regenerative capacity after injury. Current treatment options, such as conservative drug therapy and joint replacement, have inherent limitations. Achieving perfect regeneration and repair of articular cartilage remains an ongoing challenge in the field of regenerative medicine. Tissue engineering has emerged as a key focus in articular cartilage injury research, aiming to utilize cultured and expanded tissue cells combined with suitable scaffold materials to create viable, functional tissues. This review article encompasses the latest advancements in seed cells, scaffolds, and cytokines. Additionally, the role of stimulatory factors including cytokines and growth factors, genetic engineering techniques, biophysical stimulation, and bioreactor systems, as well as the role of scaffolding materials including natural scaffolds, synthetic scaffolds, and nanostructured scaffolds in the regeneration of cartilage tissues are discussed. Finally, we also outline the signaling pathways involved in cartilage regeneration. Our review provides valuable insights for scholars to address the complex problem of cartilage regeneration and repair.

Abstract
OBJECTIVE To evaluate mitochondrial DNA (mtDNA) release from injured chondrocytes and investigate the utility of synovial fluid mtDNA concentration in early detection of posttraumatic osteoarthritis. METHOD We measured mtDNA release using four models of osteoarthritis: in vitro interleukin-1β stimulation of cultured equine chondrocytes, ex vivo mechanical impact of bovine cartilage explants, in vivo mechanical impact of equine articular cartilage, and naturally occurring equine intraarticular fracture. In our in vivo model, one group was treated with an intraarticular injection of the mitoprotective peptide SS-31 following cartilage injury. mtDNA content was quantified using qPCR. For naturally occurring cases of joint injury, clinical data (radiographs, arthroscopic video footage) were scored for criteria associated with degenerative joint disease. RESULTS Chondrocytes released mtDNA in the acute time frame following inflammatory and mechanical cellular stress in vitro. mtDNA was increased in equine synovial fluid following experimental and naturally occurring injury to the joint surface. In naturally occurring posttraumatic osteoarthritis, we found a strong positive correlation between the degree of cartilage damage and mtDNA concentration (r = 0.80, P = 0.0001). Finally, impact-induced mtDNA release was mitigated by mitoprotective treatment. CONCLUSION Changes in synovial fluid mtDNA occur following joint injury and correlate with the severity of cartilage damage. Mitoprotection mitigates increases in synovial fluid mtDNA suggesting that mtDNA release may reflect mitochondrial dysfunction. Further investigation of mtDNA as a potentially sensitive marker of early articular injury and response to mitoprotective therapy is warranted.

Abstract
Articular cartilage injury, as a hallmark of arthritic diseases, is difficult to repair and causes joint pain, stiffness, and loss of mobility. Over the years, the most significant problems for the drug-based treatment of arthritis have been related to drug administration and delivery. In recent years, much research has been devoted to developing new strategies for repairing or regenerating the damaged osteoarticular tissue. The RNA interference (RNAi) has been suggested to have the potential for implementation in targeted therapy in which the faulty gene can be edited by delivering its complementary Short Interfering RNA (siRNA) at the post-transcriptional stage. The successful editing of a specific gene by the delivered siRNA might slow or halt osteoarthritic diseases without side effects caused by chemical inhibitors. However, cartilage siRNA delivery remains a challenging objective because cartilage is an avascular and very dense tissue with very low permeability. Furthermore, RNA is prone to degradation by serum nucleases (such as RNase H and RNase A) due to an extra hydroxyl group in its phosphodiester backbone. Therefore, successful delivery is the first and most crucial requirement for efficient RNAi therapy. Nanomaterials have emerged as highly advantage tools for these studies, as they can be engineered to protect siRNA from degrading, address barriers in siRNA delivery to joints, and target specific cells. This review will discuss recent breakthroughs of different siRNA delivery technologies for cartilage diseases.

The effect of adipose-derived mesenchymal stem cells and chondrocytes with platelet-rich fibrin releasates augmentation by intra-articular injection on acute osteochondral defects in a rabbit model.

Abstract
BACKGROUND This study aimed to investigate the efficacy of adipose-derived mesenchymal stem cells (ADSCs), platelet-rich fibrin releasates (PRFr), and chondrocyte transplantation in rabbit acute osteochondral defects. METHODS Thirty rabbits were randomly assigned to five groups: untreated controls; ADSCs alone; PRFr alone; PRFr + ADSCs; and PRFr + chondrocytes. The critical size osteochondral defects in right knee femoral condyles were injected intra-articularly according to the groups, as listed. The experimental rabbits received treatments once a week for two weeks postoperatively. All evaluations were conducted for 14 weeks following surgery, and the regenerated cartilages were assessed by gross inspection and histological examination. RESULTS There were no complications encountered in any of the rabbits. The size of the defect decreased and the volume of repaired cartilage increased in the medial femoral condyles of the PRFr + ADSCs group. Relative to the ADSCs or PRFr group, histological examination demonstrated that the PRFr + ADSCs group had thicker hyaline cartilage-specific extracellular matrix. Grading scores revealed that PRFr + ADSCs injection had better matrix, cell distribution, and surface indices than other groups (P < 0.05). However, the histological scores reported for PRFr + chondrocytes on cartilage repair were similar to those of PRFr, and there were no significant between-group differences. CONCLUSIONS These findings showed that intra-articular injections of PRFr + ADSCs into the knee can reduce cartilage defects by regenerating hyaline-like cartilage without complications. This approach may provide an alternative method for functional reconstruction of acute osteochondral defects with an unlimited source of cells and releasates.

Abstract
PURPOSE Focal chondral lesions of the knee are commonly occurring. A lot is known about their frequency, size and localisation in arthroscopic series, but less about the symptoms they elicit and little about how the arthroscopic findings and symptoms correlate. The purposes of the present study included to investigate the relationship between articular cartilage lesion factors and patient factors, and to compare the symptoms and function of cartilage lesion patients to those of patients with a deficient ACL. METHODS A prospective registration was conducted of preoperative data including Lysholm knee score and perioperative findings in 1,000 consecutive patients undergoing an arthroscopic procedure of the knee-including microfracture of articular cartilage defects and ACL reconstructions. RESULTS Chondral or osteochondral lesions were found in 57 % of the arthroscopies. The mean Lysholm score in this subgroup was 55. The mean Lysholm score was significantly lower in women (50, SD 19) compared to men (59, SD 18, p < 0.001). Among the chondral lesion factors, only kissing (vs. non-kissing) lesions and multiple (vs. single) lesions influenced symptoms and function to a more than negligible degree. Microfracture in one or two articular cartilage defects was performed in 187 patients. The microfracture group had a significant lower mean Lysholm score (54, SD 18) than a group of patients (N = 71) undergoing ACL reconstruction group (67, SD 17, p < 0.001). CONCLUSION The study confirms that articular cartilage lesions are both common and cumbersome. Women seem to have more problems than men, whereas chondral lesion factors-such as localisation and size-seem to influence symptoms and function to a small degree. These aspects should be addressed when designing outcome studies, and should also be of interest to the orthopaedic surgeon-in the day-by-day clinical work. When treating these patients, our prime focus need to be on knee function rather than the cartilage defect as the relationship between the latter and the former is unclear. LEVEL OF EVIDENCE Case-control study, Level III.
