Summary

To provide mechanical stability, to restore the long-term movement, to retain the damage to the tendon tendon tendon Tightrope fixed to solve the stability problem, the residual tendons in the mirror line repair and slightly stitching, without wearing tendon bone, so less damage , Also provides a complete damage to the tendon bundle fiber connection, but also conducive to the reconstruction of its surface ontology, vascular network reconstruction, but bone tunnel and other long points to be higher technical requirements, and to be more time, larger samples , More clinical criteria for long-term observation.

Abstract

Purpose

To explore the clinical efficacy of Tightrope reconstruction (simple, ie, without any tendon transplantation) in patients with partial anterior cruciate ligament rupture.

Methods

Five cases of ACL partial rupture were reconstructed under arthroscopy, and only the Tightrope device (not with tendon graft) was reconstructed by the same surgeon. The effects of Tightrope and residual tendon anastomosis on the reconstruction of cruciate ligament injury were evaluated by routine functional exercise, regular follow-up and evaluation of the indexes.

Results

Tightrope internal fixation in anterior cruciate ligament reconstruction can reduce the operation time and reduce the length of tendon fixation incision. The advantages of simultaneous reduction of bone mass loss on both sides of the tibia and femur tendon with simultaneous tendon transplantation Type unmatched. And the biomechanical stability of the Tightrope graft will always exist. It is impossible to provide biomechanical stability, but it provides the integrity of the fiber connection, is conducive to the process of scarring healing of the tendon surface, the body feel recovery and tendon surface The repair of the bundle of blood vessels also has a significant effect, and its lack of mechanical stability Tightrope is sufficient to make up.

Conclusion

1, 3, 6 months after the rehabilitation of patients in the knee maximum flexion, knee score, Tegner exercise level score 3 evaluation, the effect is satisfactory. The results suggest that only Tightrope devices (not with tendon transplantation) in situ equal length to strengthen the rupture of the tendon, anterior cruciate ligament in some of the reconstruction process, the operation is more simple, more minimally invasive, bone loss less. 6 months after the internal fixation, the clinical efficacy was satisfactory, did not need to re-accept the transplanted tendon surgery.
