Anterior Cruciate Ligament Reconstruction With a Periosteal - Patellar Tendon - Bone Autograft - The Kocabey Press-Fit Technique

Recruiting

• Conditions: Anterior Cruciate Ligament Rupture
• Interventions: Procedure: Anterior cruciate ligament (ACL) reconstruction with a periost-patellar-tendon-bone (PPTB) autograft and a tibial press-fit technique

• Registration Number: NCT06190223
• Lead Sponsor: Ankara City Hospital Bilkent

Brief Summary

This study aims to evaluate the clinical and radiological outcomes of patients undergoing anatomical single-bundle anterior cruciate ligament reconstruction with periosteal-patellar tendon-bone autograft and press-fit tibial fixation technique. The study also aims to compare these outcomes with other reconstruction techniques in the literature. The research investigates the results of a novel surgical technique, providing a minimally invasive and faster rehabilitation for patients undergoing surgery due to anterior cruciate ligament rupture. The technique does not use any screws or staples for tibial fixation, but it carries similar risks as existing techniques. The technique, similar to the well-known bone-patellar tendon-bone (BPTB) autograft technique, creates minimal bone defect at the tibial tuberosity. Over time, the defect remodels and causes minimal clinical discomfort. Despite these limitations, the authors expect patients operated with the investigated new technique to experience less postoperative swelling, less pain, faster mobilization, and earlier rehabilitation.

Arm && Interventions

Group	Intervention	Description
PPTB Group	Anterior cruciate ligament (ACL) reconstruction with a periost-patellar-tendon-bone (PPTB) autograft and a tibial press-fit technique	Patients will undergo anterior cruciate ligament reconstruction with the novel PPTB graft and a tibial press-fit technique.

Primary Outcome Measures

Name	Time	Method
Tegner-Lysholm Scale	Postoperative 1.st year	minimum value:0, maximum value 100, higher values mean better outcome
The Knee injury and Osteoarthritis Outcome Score (KOOS)	Postoperative 1.st year	minimum value:0, maximum value 100, higher values mean better outcome
The International Knee Documentation Committee Score (IKDC)	Postoperative 1.st year	minimum value:0, maximum value 100, higher values mean better outcome
Graft survival	Postoperative 1.st year	Overall graft survival

Secondary Outcome Measures

Name	Time	Method
Tunnel widening	Postoperative 1.st year	Tibial and femoral tunnel widening will be measured on direct calibrated Xrays as a distance (in millimeters) and on CT scans taken at the sixth postoperative month. The distance will be measured on the widest point between the sclerotic lines on the Xrays and perpendicular to their longitudinal trajectories.
