The YDFIX argeting System is designed to surgically treat full thickness femoral articular cartilage lesions via autograft or allograft transplantation. It is a completely disposable, sterile-packed system designed for single-patient use. YDFIX Precision Targeting may be used in an arthroscopic or an open procedure if access to the defect or donor site is difficult. Generally, the ideal patient for this procedure is one with a focal traumatic lesion, between 1 cm and 2.5 cm in diamete , in weight-bearing regions of the femoral condyle. The YDFIX Precision Targeting System offers surgeons a choice of 4 mm, 6 mm, 8 mm, and 10 mm diameter sizes and variability for graft plug depth.
