Persona Partial Knee System Spacer Block Alignment Tower, Item No. 42-5399-006-35 Product Usage: Intended to aid in preparatory surgical procedures
The PPK System Spacer Block Alignment Tower mating feature that mates with the spacer block was undersized, which could potentially lead to mating issues between the devices. This could cause a delay in surgery of less than 30 minutes. There is an option in the surgical technique for performing limb alignment without the alignment tower.
