Cartilaginous abrasion and debridement: correlation between type of cartilaginous injury and results in patients with a 4 to 9-year follow-up.

It is the purpose of this study to verify whether or not there is a correlation between some parameters for cartilaginous injury (width, depth, and type of injury), analyzed separately, and the medium to long-term prognosis of the same. Thus, the parameters were analyzed, correlating them individually with the results obtained when a self-evaluation form was used, and the Lysholm-Gillquist score system. The small number of patients (because of the strict criteria for inclusion) does not allow for a statistically valid analysis of the results obtained. At any rate, the following considerations may be made: the depth parameter for the injury may be a valid element alone in determining a medium- to long-term prognosis; this agrees with what is reported in the literature. The parameter for width of the injury, based on our results, does not appear to be a sufficient element to determine a correlation with future prognosis. As for the type of lesion parameter, this could be correlated with the prognosis. Studies conducted in this sense with higher numbers of patients could determine the type of injury with the worst prognosis.
