Nonanatomic Posterolateral Tenodesis for Posterior Ligament Reconstruction Augmentation.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanics

Background:

• Posterior cruciate ligament (PCL) reconstruction is crucial for knee stability.
• Standard PCL reconstruction techniques report residual laxity in up to 26% of cases.
• Posterior tibial translation and external tibial rotation are common issues post-reconstruction.

Purpose of the Study:

• To introduce a novel surgical technique combining single-bundle PCL reconstruction with posterolateral tenodesis.
• To address limitations in current PCL reconstruction methods, specifically residual laxity and rotational instability.
• To evaluate this augmented technique for isolated PCL ruptures, including those with posterolateral corner injuries.

Main Methods:

• Description of a surgical technique involving single-bundle PCL reconstruction.
• Integration of a posterolateral tenodesis augmentation into the PCL reconstruction procedure.
• Application of the technique for grade III PCL ruptures, with or without concomitant low-grade posterolateral corner injuries.

Main Results:

• The described technique aims to improve control over posterior tibial translation.
• The augmentation is intended to reduce external tibial rotation after PCL reconstruction.
• This approach is proposed for complex PCL injuries, potentially reducing failure rates.

Conclusions:

• Posterolateral tenodesis augmentation offers a potential solution to improve PCL reconstruction success rates.
• This combined technique may enhance stability and reduce residual laxity in PCL-deficient knees.
• Further studies are warranted to validate the clinical efficacy and long-term outcomes of this augmented approach.
