A presentation on Articular Cartilage Repair for my Functional Anatomy Course. The presentation was short as we were limited to 6 slides.

I hope you find the information of some use.

Articular Cartilage Repair

  1. 1. Rebuilding from the ground up.
  2. 2.  Anti-inflammatory Medication or Systemic Steroids  Injections  Corticosteroids  Hyaluronic Acid  Surgery (major types)  Bone Marrow Stimulation (e.g. Microfracture)  Mosaicplasty  Surgery combined with tissue engineering (e.g. Autologous Chondrocyte Implantation (ACI))
  3. 3.  Growth Factors  The transforming growth factor beta (TGF-β) superfamily, specifically the BMPs, CDMPs, OPs, and GDFs, have a dramatic effect on the development of bone and cartilage tissue.  These growth factors help produce an extracellular matrix that can withstand extreme loading conditions in the body.  Mechanical Loading  Load-bearing tissue, such as articular cartilage, will atrophy in the absence of mechanical forces
  4. 4. Design Criteria Types Advantages • Biocompatibility • Natural • deliver the repair materials to the site of injury • Limit immune reaction responses • Fibrin • Induce maturation and • Agarose and Alginate • remain in place long enough to differentiation of cellular effect repair • Collagen structures that they are to • Chitosan • provide an even distribution of support • Hyaluronan implanted cells • Biodegrade into non-harmful substances • provide an instructive three • Synthetic dimensional environment for • Polylactic Acid (PLA) seeded and colonising cells • Structural integrity & • Polyglycolic acid (PGA) stability • allow for the controlled local • PLA-PGA Copolymer delivery of polypeptide or chemical molecules that • Durability stimulate repair • the ability of the scaffold to be retained at the implantation site
