Background: knee cartilage lesions are very frequent due to traumatic and degenerative causes. The possibility of recovery of this tissue is low because of its limited cellular population. That`s the reason why is necessary the application of surgical treatments to get the reparation or reconstruction of the cartilage. Microfractrure is a first-line technique for treating this disease; however, the absence of proper instruments hinders its carrying out. Objective: to validate the proposed instruments for carrying out microfractures in the knee joint. Method: for the validation of the designed instruments used for carrying out microfractures, the Delphy method was applied through a consultation to a group of experts composed of 16 specialists in Orthopedics and Traumatology with an average of 15.3 years of professional experience, a Doctor of Sciences, 13 Masters of Sciences, five specialists of second degree, three associate professors and two full professors. Results: values corresponding to the absolute-frequency matrix, to the accumulated-frequency matrix, to the accumulated-relative-frequency matrix, and to the indicative matrix of cutting points were displayed. Conclusions: the proposed instruments by the authors were validated regarding: application, design, and reproducibility.
