Anatomic Double Bundle Posterior Cruciate Ligament Reconstruction Using an Internal Splint

Area of Science:

• Orthopedic surgery
• Biomedical engineering
• Sports medicine

Background:

• Posterior cruciate ligament (PCL) tears often require surgical reconstruction.
• Current PCL reconstruction methods face challenges with early postoperative laxity and tibial translation.
• Maintaining tibial reduction during graft healing is crucial for successful outcomes.

Purpose of the Study:

• To present a novel technique for posterior cruciate ligament (PCL) reconstruction using an internal splint.
• To address the issue of early postoperative laxity and relapsed tibial translation in PCL tears.
• To optimize graft incorporation and stability in 4-tunnel, double-bundle allograft PCL reconstruction.

Main Methods:

• Description of a surgical technique employing an internal splint for PCL reconstruction.
• Utilizing a 4-tunnel, double-bundle allograft approach.
• Focus on maintaining tibial reduction throughout the graft incorporation phase.

Main Results:

• The internal splint technique aims to enhance tibial fixation during the critical early healing period.
• This method is designed to prevent the development of postoperative laxity.
• Optimization of graft incorporation is expected, leading to improved PCL reconstruction stability.

Conclusions:

• The internal splint technique offers a potential solution to improve stability in PCL reconstruction.
• This method targets the prevention of early graft loosening and tibial subluxation.
• Further evaluation is needed to confirm the long-term efficacy of this approach in PCL surgery.
