Comparison of Autologous Quadriceps and Hamstring Tendon Grafts in Anterior Cruciate Ligament Reconstruction

Condition(s) studied

Investigational drug(s) / intervention(s)

Anterior Cruciate Ligament Reconstruction with Quadriceps 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.

Anterior Cruciate Ligament Reconstruction with Hamstring Autograft: The investigators will perform all-inside anterior cruciate ligament reconstruction using the hamstring tendon as a graft in this group.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Autograft Maturation — 12 months
  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.
• Stability of Knee — 9 months
  Pivot shift test
• Stability of Knee — 9 months
  laxity measuring with KT-1000 device
• Stability of Knee — 9 months
  Lachman test
