A clinical case of anterior cruciate ligament B-PT-B salvage surgery with the VEGA One Step Navigator

Type of surgical intervention:

B-PT-B technique anterior cruciate ligament salvage surgery and anterolateral reinforcement with a locking system.

The first ever B-PT-B technique anterior cruciate ligament salvage surgery performed using VEGA One Step surgical planning and navigation with customized medical instrumentation and implants.

Performed by:
Dr Juanjo López Martínez
Dr Alonso Lisón Almagro

INTRODUCTION

We performed the first ever complex anterior cruciate ligament salvage surgery using the VEGA LCA one Step planning and navigation system.

The patient suffered a complete tear of the anterior cruciate ligament during infancy. Anterior cruciate ligament reconstruction was performed with a femoral tunnel in a more horizontal position than is usual in order to avoid damage to the distal femoral physis. Further to protocol rehabilitation, the patient recuperated perfect function and stability. However, in May 2020, aged 19, the patient was involved in a cycling accident that resulted in serious knee valgus collapse. The anterior cruciate ligament of the knee that had been treated during infancy was torn once again.

On this occasion, Dr Juanjo López and Dr Alonso Lisón used our surgical planning and navigation systems. The surgery was incredibly complicated due to the tunnels that had been made during the first intervention, accentuated by the fact that the patient was young and had previously had a hamstring graft.

AIMS

First of all, the case underwent a surgical planning process. We reconstructed the patient’s knee in 3D and, under the doctors’ supervision, designed the most suitable position, the exact dimensions and the perfect trajectories for the necessary femur and tibia bone tunnels. A B-PT-B patellar tendon plasty was used.

Thanks to the VEGA LCA One Step Navigator, we were able to apply the pre-surgery surgical plan to the surgical intervention itself. This process:

  • Achieves EXCELLENCE IN SURGERY.
  • Decreases the duration of surgery since the navigator does not need to be programed
  • Decreases the amount of medical instrumentation that is required.
  • Above all, it increases graft position precision.
  • Drastically decreases stress during surgery and avoids uncertainty during the intervention.
  • Reduces the risk of infection.

It must be kept in mind that the main cause of unsuccessful ligament reconstruction surgery is incorrect bone tunnel position, particularly in the case of the femur tunnel.

THE RESULT

Dr Juanjo López and Dr Alonso Lisón performed surgery that translated into absolute EXCELLENCE IN SURGERY. As a result, the patient is able to enjoy the outcome with a stable knee that has undergone flawless surgery.
