Synthetic Polymer. Synthetic polymers are an attractive class of materials due to the ability to tailor the material properties for specific applications such as altering the molecular weight or chemistry to influence degradation or mechanical properties (Kohane and Langer, 2008; Guo and Ma, 2014). Synthetic polymers are sometimes referred as “plastics”, of which the well-known ones are nylon and polyethylene. The polymers which are formed by linking monomer units, without the any change of material, are known to as addition polymers or also called as chain-growth polymers. All these are said to be synthetic polymers.

Their mechanical stability is relatively low, even causing failure of surgery, but they have the clear advantage of interaction with the host tissue, cell adhesion, proliferation and matrix remodeling. Synthetic polymers for ligament or tendon repair are polypropylene, ePTFE, PET/Dacron, nylon. polymers produced by plants and animals, primarily proteins (collagen, keratin) and carbohydrates (cellulose, starch).
