Instabilità di rotula: Trattamento delle lesioni condrali con innesto autologo di condrociti

The reasons of the cartilage lesions in patellar instability can be different: sports or traffic trauma and ostheocondritis dissecans can determine a more or less important lesions of patellar cartilage, but certainly a very important role can be covered by pathological conditions such as potential patellar instability or objective patellar instability. This pathological conditions lead anyway to an abnormal patellar tracking responsible of a chondral lesion. The surgical techniques are various and the target is to correct an abnormal patellar tracking, but only in the last few years new surgical techniques are arised to treat the chondral lesions with the target to reconstitute the cartilage tissue. We have reviewed the personal casistics of autologous chondrocytes implantation combined with the Emslie-Trillat procedure with a medium follow-up of 32 months with the conclusions that when there's a patellar chondral lesion of III-IV up to Outerbridge classification and a malalignment conditions, the alone Emslie-Trillat procedure can represent an incomplete treatment no matter what the place of the cartilage lesion is. Infact when the cartilage is damaged it doesn't recover but it will get worst. Therefor a process will take place and it is indipendent from the cause that generated it. If not corrected the chondral lesion can lead to a useless realignment procedure and at the end to compromise the function of patellar-femoral joint.
