abstract：:The current paradigm in tissue engineering is that "full regeneration" or "total replacement" of normal tissue is required in order to restore joint function. However, there is considerable evidence that suggests that targets other than "normality" may actually be required for tissue substitutes. Sometimes "less than ...
