All-suture anchor, instruments, and methods of using the same

A method of attaching a suture anchor assembly to a bone, comprising:

• drilling a pilot hole into the bone using a drill;
• inserting an anchor into the pilot hole via an insertion tool, the anchor comprising:
• a sleeve having an elongated configuration and a tightened configuration;
• a first deployment strand and a second deployment strand, each of the first deployment strand and the second deployment strand forming a looped end and a free end, wherein:
• the free end of the first deployment strand passes through the looped end of the second deployment strand and the free end of the second deployment strand passes through the looped end of the first deployment strand, thereby forming a loose square knot with a first crossover and a second crossover;
• and
• a portion of the first deployment strand and a portion of the second deployment strand pass through the sleeve;
• deploying the anchor by tensioning the free end of the first deployment strand and the free end of the second deployment strand, thereby tightening the square knot and causing the sleeve to move to the tightened configuration;
• and
• removing the insertion tool from the pilot hole.

A kit for attaching a suture anchor assembly to a bone, comprising:

• a drill configured to drill a pilot hole into the bone;
• an insertion tool configured to insert a suture anchor assembly into the pilot hole;
• and
• the suture anchor assembly comprising:
• a sleeve including an elongated configuration and a tightened configuration;
• a first deployment strand and a second deployment strand, each of the first deployment strand and the second deployment strand forming a looped end and a free end, wherein:
• the free end of the first deployment strand passes through the looped end of the second deployment strand and the free end of the second deployment strand passes through the looped end of the first deployment strand, thereby forming a loose square knot with a first crossover and a second crossover;
• a portion of the first deployment strand and a portion of the second deployment strand pass through the sleeve;
• and
• application of tension to each of the free end of the first deployment strand and the free end of the second deployment strand causes the loose square knot to tighten and the sleeve to move to the tightened configuration.
