Systems, kits, and devices for drilling articular cartilage and methods thereof

A method of preparing articular cartilage for receiving a graft tissue, comprising:

• connecting a drill collar to a drill bit;
• inserting a distal end of the drill bit into an adjustable shaft collar of a handle device;
• advancing the distal end of the drill bit through an internal cannulation of the handle device until the distal end of the drill bit is proximate a distal tip of a distal drill guide of the handle device and the drill collar abuts a rotatable disk disposed between the drill collar and the adjustable shaft collar;
• and
• rotating the adjustable shaft collar to cause the adjustable shaft collar to move axially with respect to a handle of the handle device until the distal end of the drill bit extends from the distal drill guide a desired drill depth.

A kit for removing portions of articular cartilage, the kit comprising:

• a handle device comprising:
• a handle;
• an adjustable shaft collar rotatable to adjust a drill set distance between the adjustable shaft collar and the handle;
• and
• a distal drill guide extending from the handle at an end opposite the adjustable shaft collar;
• a drill bit;
• a drill collar attachable to the drill bit;
• a rotatable disk positionable between the adjustable shaft collar and the drill collar, the rotatable disk including a central hole sized to accept the drill bit;
• and
• a first measuring guide configured to measure a depth of a circular defect created by the drill bit.
