Tension reduction line weaving method for cruciate ligament reconstruction and tension reduction line thereof

Abstract

The invention relates to a tension reducing line for cruciate ligament reconstruction and a weaving method thereof, and belongs to the technical field of anterior and posterior cruciate ligament reconstruction. The method comprises the five steps of suture preparation, suture fixation, initial knitting, middle-stage knitting and ending knitting. The single suture is woven and then placed in the middle of the transplanted tendon, the weaving method can further enhance the strength and overcome the defect that the tension reducing line is prone to being broken in the early stage, meanwhile, the internal fixing effect of the tension reducing line is achieved, excessive stress stimulation is prevented from acting on the reconstructed ligament in the ligament shaping and reconstruction period, and the ligament shaping and reconstruction effect is improved. The rebuilt ligament is prevented from being lengthened, healing of the rebuilt ligament is facilitated, the diameter of the rebuilt ACL or PCL can be properly increased, the area of the ACL or PCL is attached to the inner surface of a bone tunnel as much as possible, and tendon-bone healing is better and faster.

Description

[0001] This application is a divisional application for the invention patent of the parent application titled "A tension-reducing thread for cruciate ligament reconstruction and its braiding method"; the application number of the parent application is: CN201710572127.4; the filing date of the parent application For: 2017-07-13. technical field [0002] The invention relates to the technical field of reconstruction of anterior and posterior cruciate ligaments, in particular to a weaving method of a tension-reducing thread for cruciate ligament reconstruction and the tension-reducing thread thereof. Background technique [0003] In recent years, with the rapid development of sports in my country and the extensive development of national fitness campaigns, injuries to the Anterior Cruciate Ligament (ACL) or Posterior Cruciate Ligament (PCL) of the knee joint have gradually increased. The function of the cruciate ligament is very important. If the ACL or PCL of the knee joint is...

AI Technical Summary

Problems solved by technology

[0005] It has been reported that the reconstruction of the anterior and posterior cruciate ligaments is carried out by using the tension-reducing technique within the grafted tendon, that is, adding a tension-reducing line to the grafted tendon for ACL or PCL reconstruction and early rehabilitation training, which ensures the smooth progress of early rehabilitation training. The results show that the Technology can prevent the reconstructed ligament from being elongated, thereby improving the clinical efficacy. However, many studies have found that in the early rehabilitation process after ACL or PCL reconstruction, when the patient bends the knee to a certain angle, there is a sound in the joint, and then the knee bends more smoothly. In this case, it was confirmed that the tension-reducing line was broken after early arthroscopic exploration, which was caused by the insufficient strength of the tension-reducing line, and the tension-relieving effect could not be fully exerted.

The inventors of the present application found after research that in the process of ACL or PCL reconstruction, there is a certain difference in the stability of the knee joint whether the ACL or PCL is reconstructed with the tension reduction technique
