Anterior Cruciate Ligament Injuries Clinical Trial

Official title: Evaluation of the Results of Two Different Methods in Management of Antero-lateral Instability of the Knee

Status Recruiting

Clinical Trial Summary

This randomized clinical study will be conducted to compare the results of anterior cruciate ligament reconstruction (ACLR) combined with either anterolateral ligament reconstruction using peroneus longus autograft or extra-articular tenodesis (Modified Lemaire) in management of antero-lateral instability of the knee

Clinical Trial Description

Patients will undergo an anatomic ACLR in a standardized fashion by the same team of surgeons. They are randomly divided into 2 groups either ACLR plus ALL reconstruction or ACLR combined with LET in a 1:1 ratio. There are multiple graft options for ACL-R, but here for the study, the hamstring autograft is harvested following the traditional technique. The graft is measured and bony tunnels are drilled. An anatomical reconstruction technique is used in all cases.

In group A: the surgeon will harvest peroneus longus graft, then sutured to the double bundle hamstring graft. The graft diameters are measured and recorded. The graft is pulled through the femoral tunnel and passed through the tibial tunnel. The single portion of the graft is passed freely through the tibial and femoral tunnels until the quintuple graft portion occupies both tunnels. The graft is then pulled, and an interference screw (Smith & Nephew Endoscopy) is fixed to the femur. The next step is to fix the inferior end of the quintuple graft to the tibia after pre-tensioning. After tibial fixation, the remaining PL is passed through the subcutaneous and ALL tunnels. The ligament is fixed under traction, mild valgus stress, and 30' of flexion 1.5 cm from the joint line into a midpoint between Gerdy's tubercle and the fibular head.

In group B: the surgeon will use a triple STG hamstring (6- strands) tendon graft. The graft diameters are measured and recorded.

Then, LET is performed in a standardized fashion as described in the modified Lemaire technique. LET is fixed with interference screws (Smith & Nephew Endoscopy). Femoral and tibial fixations are performed with bio-absorbable interference screws (Smith & Nephew Endoscopy). ;
