Influence of Combined Double-Bundle ACL Reconstruction With Lateral Retinacular Release to Prevent Patellofemoral Malalignment in Isolated ACL Rupture

Influence of Combined Double-Bundle ACL Reconstruction With Lateral Retinacular Release to Prevent Patellofemoral Malalignment in Isolated ACL Rupture: a Randomized Controlled Trial

Anterior knee pain which might be due to patellofemoral malalignment is an inevitable post operative complication after an ACL reconstruction (ACLR). We combined the double bundle ACLR technique with lateral release technique to prevent patellofemoral malalignment post ACLR.

Inclusion Criteria:

• unilateral isolated total ACL rupture
• normal BMI

Exclusion Criteria:

• flexion contracture more than 200, presence of anterior knee pain before surgery, Q angle >140 in males and >170 in females, presence of a patellar tilting, rupture of other ligaments, and muscular dysfunction.
