Abstract: A perforation instrument and method of using same, including a shaft capable of being inserted into a joint of a patient, having a longitudinal axis, and carrying at least one piercing member, each piercing member having a tip suitable to pierce sub-chondral bone. The instrument is capable of being altered between an exposed condition wherein the tip of the at least one piercing member is exposed and a safety condition wherein the tip of the at least one piercing member is not capable of piercing tissue.

Abstract: Methods and devices are provided for forming holes in bone to stimulate bone growth. In one exemplary embodiment, a surgical instrument set can include a driver having a first mating element, and a bone pick have a second mating element configured to releasably mate with the first mating element at any of a plurality of angular orientations. When releasably mated together, the driver and the bone pick can be configured to be adjustably positioned relative to one another with three degrees of freedom, e.g., pitch, yaw, and roll. The bone pick can include a piercing tip configured to form a hole in a bone, such as in microfracture. When the driver and the bone pick are releasably mated together, the driver can be configured to be struck, impacted, or otherwise manipulated to drive the piercing tip into the bone.
