An interventional study of Anterior Cruciate Ligament Reconstruction with Quadriceps Autograft and Anterior Cruciate Ligament Reconstruction with Hamstring Autograft in Anterior Cruciate Ligament Injuries, Athletic Injuries and Tendon Graft; Complications, sponsored by Muzaffer Agir. Recruiting at 1 site in Turkey. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-09-27.
Sponsored by Muzaffer Agir · Not applicable, Interventional, and Treatment
With the recent technological advancements, the use of the quadriceps tendon with an all-inside technique has come to the forefront, and large-scale research has focused especially on quadriceps tendon grafts. Clinical study results have reported that the outcomes are similar to those of patellar tendon grafts and either equivalent or superior to hamstring tendon grafts.
The aim of this study is the prospective comparison of the clinical and radiological outcomes of patients who underwent anterior cruciate ligament (ACL) reconstruction with autologous hamstring and quadriceps tendon grafts.
625 studies on the registry are indexed under Anterior Cruciate Ligament Injuries; 192 are open to participants now.
This study's planned enrollment of 25 is below the median of 56 across 458 interventional studies indexed under Anterior Cruciate Ligament Injuries.

Exclusion Criteria:
Procedure: Anterior Cruciate Ligament Reconstruction with Quadriceps Autograft
Procedure: Anterior Cruciate Ligament Reconstruction with Hamstring Autograft
The investigators will perform all-inside anterior cruciate ligament reconstruction using only the tendon portion of the quadriceps tendon (without bone fragments) in this group.
The investigators will perform all-inside anterior cruciate ligament reconstruction using the hamstring tendon as a graft in this group.
Autograft Maturation
Comparison of different autografts maturation on MRI images. The signal-to-noise quotient formula will be used to assess graft maturation. According to the method described by Chan and Yau, the difference between the signals of the ACL graft and the quadriceps tendon will be used to evaluate maturation by relating it to the background signal.
