简要总结
Anterior Cruciate Ligament (ACL) reconstruction is one of the most commonly performed orthopedic procedures. Tibial tunnel widening is a recognized postoperative complication that may affect graft stability and long-term outcomes. Recent studies have suggested that preserving the ACL remnant may improve biological healing and reduce tunnel widening, but the evidence remains inconclusive.
This prospective randomized study aims to evaluate whether remnant (stump) preservation and suturing during ACL reconstruction can reduce the risk of tibial tunnel widening compared with the conventional stump-resection technique.
A total of 190 patients with recent ACL tears (<6 months) were randomly assigned into two equal groups: Group A underwent arthroscopic ACL reconstruction with remnant suturing, while Group B underwent standard reconstruction with stump resection. All patients were followed for 12 months postoperatively with serial CT evaluations to assess tunnel diameters and positioning.
