In this video, we demonstrate suturing techniques — core suture and Q suture — to repair the foot flexor tendon in an ex vivo porcine model. Q sutures enhance the strength of the core suture in tendon repair and decrease gapping at the tendon repair site.

In molecular biology, ligation refers to the joining of two DNA fragments through the formation of a phosphodiester bond. An enzyme known as a ligase catalyzes the ligation reaction. In the cell, ligases repair single and double strand breaks that occur during DNA replication. In the laboratory, DNA ligase is used during molecular cloning to join DNA fragments of inserts with vectors – carrier DNA molecules that will replicate target fragments in host organisms.

The surgical procedure used to induce experimental myocardial infarction in mice begins with left thoracotomy between the third and the fourth ribs in order to visualize the anterior surface of the heart and left lung. The left coronary artery is ligated, the chest is closed and the mouse is allowed to recover spontaneously.
FAQs
Outcome depends on how precisely the suture is positioned, how securely the knot is tied, the properties of the tissue, and how long the ligature remains tightened. These variables determine whether compression is sufficient to occlude the target and whether the intended restriction is maintained. Controlling them is therefore central to producing consistent experimental results.
Knot security determines whether the applied compression remains in place around the target. A knot that does not hold can reduce or interrupt the intended occlusion, while a securely maintained knot supports a more stable restriction over the selected duration. This matters when researchers want comparable tissue separation, hemostasis, or vascular responses across experimental preparations.
Duration is an experimental variable because the effect of compression is not independent of time. A brief or prolonged ligation can therefore produce different degrees or patterns of restriction, influencing models of vascular obstruction or ischemia. Recording and controlling how long the ligature remains tightened helps researchers relate observed tissue responses to the intended experimental condition.
Performing the technique requires locating the defined target, passing the suture around it, tightening the ligature to create the intended compression, and securing the knot. Researchers must also maintain careful placement so the target is restricted without unnecessary injury to surrounding tissue. This controlled workflow supports reproducible hemostasis, separation, or experimental obstruction.
At a practical level, the method can stop bleeding by compressing a vessel or separate a selected tissue structure from its contents or flow. These uses make it relevant to controlling blood loss and to experimental tissue manipulation. The specific result still depends on placement, knot security, tissue properties, and the duration of ligation.
Vascular obstruction and ischemia models use the controlled restriction created by a ligature to examine what happens when blood flow is limited. Because placement, knot security, tissue properties, and duration can be controlled, researchers can relate the imposed condition to subsequent tissue responses. This makes the approach useful for investigating circulation and disease mechanisms.
After ligation, investigators can assess tissue responses, changes related to circulation, repair, and disease mechanisms. The value of these observations comes from linking them to the conditions imposed during the procedure rather than treating every ligation as identical. Consistent placement and knot security, together with a defined duration, improve the interpretability of comparisons among experimental preparations.
