Abstract

Exemplary systems and methods encompass suture knot tools and suture knot tools pre-loaded with sutures for use in tendon repair and other surgical procedures. Related methods may include forming a nail knot between a suture and a tissue of a patient during a surgical procedure by drawing tissue into a port sleeve of an arthroscopic system, moving the port sleeve relative to a free end portion of the tissue and a nail knot cinch of a suture, to allow the nail knot cinch of the suture to contact the free end portion of the tissue; and tightening the nail knot cinch of the suture about the free end portion of the tissue, so as to form the nail knot with the suture and the tissue.

Claims (12)

1. A method of forming a nail knot between a suture and a fibrous connective tissue of a patient during an arthroscopic procedure, the method comprising:

drawing a free end portion of the fibrous connective tissue into a port sleeve of an arthroscopic system so that the free end portion of the fibrous connective tissue is disposed within the port sleeve, wherein a nail knot cinch of the suture is disposed external to the port sleeve;

moving the port sleeve relative to the free end portion of the fibrous connective tissue and the nail knot cinch of the suture, to allow the nail knot cinch of the suture to contact the free end portion of the fibrous connective tissue; and

tightening the nail knot cinch of the suture about the free end portion of the fibrous connective tissue, so as to form the nail knot with the suture and the fibrous connective tissue.

2. The method according to claim 1 , wherein the step of tightening the nail knot cinch of the suture about the free end portion of the fibrous connective tissue comprises pulling a proximal portion of the nail knot cinch in a proximal direction relative to a central loop of the nail knot cinch.

3. The method according to claim 2 , wherein the step of tightening the nail knot cinch of the suture about the free end portion of the fibrous connective tissue further comprises pulling a distal portion of the nail knot cinch in a distal direction relative to a central loop of the nail knot cinch.

4. The method according to claim 1 , wherein the port sleeve is disposed at least partially within a joint space of the patient.

5. The method according to claim 1 , wherein at least a portion of the port sleeve is disposed within a port and a suture cap is disposed about the nail knot cinch, when the port sleeve is moved relative to the free end portion of the fibrous connective tissue and the nail knot cinch of the suture.

6. The method according to claim 1 , wherein the fibrous connective tissue is a diseased fibrous connective tissue or a damaged fibrous connective tissue.

7. The method according to claim 1 , wherein the fibrous connective tissue comprises a member selected from the group consisting of a tendon and a ligament.

8. The method according to claim 1 , wherein the fibrous connective tissue comprises a tendon.

9. The method according to claim 1 , wherein the fibrous connective tissue comprises a ligament.
