Regeneration of the anterior cruciate ligament: Current strategies in tissue engineering

Figure 1 Comparison of the current clinical strategy in anterior cruciate ligament surgery to tissue engineering approaches. The current “golden standard” in the clinical routine is the use of autologous tissue grafts such as semitendinosus (depicted in the figure) or patellar tendon. In tissue engineering approaches, scaffolds alone or in a combined fashion with cells or growth factors are used to improve tissue regeneration.
