Materials that enhance bone and cartilage regeneration promise to be valuable in both research and clinical applications. Both natural and synthetic polymers can be used to create scaffolds that support cells and incorporate cues which guide tissue repair. Recently, electrospinning, peptide self-assembly and biomineralisation have been employed to fabricate nanostructured scaffolds that better mimic the complex extracellular environment found within tissues, in vivo. The incorporation of peptide motifs recognised by cell receptors and the use of recombinant DNA technology have enabled the creation of scaffolds with new levels of biofunctionality. Advances in materials design will enhance our ability to create highly tailored cellular environments for bone and cartilage regeneration.

Osteochondral lesions of the talus involve injury to the articular cartilage and underlying subchondral bone. These lesions are difficult to treat because of the poor blood supply and poor regenerative capacity of the talar articular cartilage. It is important to provide a comprehensive overview of the clinical presentation, diagnostic tools, and nonsurgical and surgical treatment strategies for osteochondral lesions of the talus.

Thorough preoperative planning is essential, including a determination of the precise location of any deformity (proximal tibia, distal femur, or both). High tibial osteotomies and distal femoral osteotomies can be performed in isolation, or jointly in the form of a double-level osteotomy, for correction of coronal and/or sagittal deformity of the knee.

Recently, there has been increased attention on the treatment of cartilage repair. Overall, we constructed PHBVHHx-COL, a composite hydrogel of PHBVHHx-co-PEG and collagen, and evaluated its cartilage repair efficacy through and studies using hydrogel loaded with peripheral blood-derived mesenchymal stem cells (PBMSCs). Rheological properties and compressive mechanical properties of the hydrogels were systematically evaluated.

Background: Extra-articular but severely comminuted distal basal fractures of the proximal phalanx (PP) are rarely reported. Therefore, the aim of this study was to achieve proper union and desirable outcomes using low-profile locking plates/screws. We introduced our own surgical approach and reported the clinical/radiographic outcomes via retrospective case series.

High transductive loss at tissue injury sites impedes repair. The high dissipation characteristics in the electromechanical conversion of piezoelectric biomaterials pose a challenge. Therefore, supramolecular engineering and microfluidic technology is utilized to introduce slide-ring polyrotaxane and conductive polypyrrole to construct stress-electric coupling hydrogel microspheres.
