Abstract:
Background: The anterior cruciate ligament (ACL) is crucial for knee joint stability,
and its rupture is common often resulting from sports or road traffic accidents. ACL
reconstruction using hamstring autografts is commonly utilized, yielding positive
clinical outcomes. A suspensory method is widely used, which an adjustable loop
endobutton device providing various advantages over a fixed loop endobutton. This
study aims to evaluate the functional outcomes of arthroscopic ACL reconstruction
with a quadrupled semitendinosus autograft using an adjustable loop ebdobutton on
the femur and a suture disc for the tibia.
Material and methods: A prospective clinical study was conducted from Auguest
2022 to January 2024 at Shri B.M Patil Medical College, Hospital and Research
Centre, Vijayapura. The study included 33 patients with ACL tear operated with
arthroscopic ACL reconstruction with quadrupled semitendinosus autograft using an
adjustable loop endo-button on the femoral and a suture disc on the tibial side.
Functional outcomes were assessed using the Lysholm and International Knee
Documentation Committee (IKDC) scores preoperatively and at 6 and 12 months
postoperatively.
Results: Significant improvements were observed in both Lysholm and IKDC scores
at 6 and 12 months postoperatively (p < 0.05). The majority of patients (95%)
returned to their pre-injury level of activity. The study observed minimal
complications, with a low incidence of postoperative anterior joint laxity and no cases
of tunnel widening.
Conclusion: The use of an adjustable loop endo-button and suture disc for ACL
reconstruction with a semitendinosus quadrupled graft gives excellent functional
outcomes, significant improvement in knee stability and predictably reproduces graft
tunnel healing and maintaining its strength till healing is complete.
