Comparison of Semitendinosus and Quadriceps Grafts for Anterior Cruciate Ligament Reconstruction

Not Applicable

Active, not recruiting

• Conditions: ACL Injury; ACL

• Registration Number: NCT06167343
• Lead Sponsor: Universidad de Granada

Brief Summary

To investigate the differences between the two methods for reconstruction of the anterior cruciate ligament (ACL), to support the development of the best method for young federated male football players. After surgery with quadricipital tendon graft or semitendinosus tendon graft, a two-year follow-up and the rate of return to sport are proposed.

Detailed Description

The anterior cruciate ligament is one of the most common traumatic injuries in football, and surgery is proposed to restore knee stability. However, following surgery, few studies have focused on functional recovery of the knee with a wide arsenal of physical tests. Therefore, this study aims to study the efficacy for young football players of two types of grafts based on the most common tendons, the quadricipital and the semitendinosus (without the semimembranosus). Follow-ups will be performed at three months, six months, one year and two years after reconstruction. The variables measured will be isokinetic strength of flexors and extensors, unipodal jump test, self-perceived function, pain and tendon architecture with ultrasound.

Primary Outcome Measures

Name	Time	Method
Lower limb strength	Participants will be followed over 24 months	assessed by an isokinetic test with an isokinetic dynamometer (HUMAC NORM)
Horizontal hop test	Participants will be followed over 24 months	assessed by horizontal jump with one leg and hands on the waist, measured with a centimetric tape (three jumping opportunities)

Secondary Outcome Measures

Name	Time	Method
Perimeters	Participants will be followed over 24 months	measured with the volume of both legs (injured and uninjured) using the mid-thigh circumference.
Self-reported functionality	Participants will be followed over 24 months	assessed by Tegner Lysholm Knee Scoring Scale and Modified Cincinnati Rating System Questionnaire (Spanish version)
Knee pain	Participants will be followed over 24 months	assessed by Visual Analogue Scale (VAS) for knee pain. The subjective perception of pain from 0 to 10 will be registered. Higher scores mean a worse outcome.
Pressure pain threshold	Participants will be followed over 24 months	Using a digital algometer in epicondyle, vastus lateralis, vastus medialis and quadricipitalis tendon, patellar tendon, and insertion of the semitendinous tendon
Tendon ultrasound	Participants will be followed over 24 months	it will monitor the morphology of the tendon and their surgical gap using ultrasound (Samsung HM70A echograph and Samsung Phased Array PE2-4 probe)
