Step-by-Step Process

Steps
  • 1.
    Patient positioning
    • I.
      After anesthesia induction, bilateral stability and range of motion is assess.
    • II.
      Place a well-padded high-thigh nonsterile tourniquet.
    • III.
      Shift the patient closer to the leg post to produce a proper valgus when needed.
    • IV.
      After sterile drape, an assistant should drop the end of the bed allowing a 90° flexion.
  • 2.
    Diagnostic arthroscopy
    • I.
      Through the standard portals (anteromedial and anterolateral), pay special attention to the integrity of the other ligaments, the femoral notch width and the presence of associated injuries.
  • 3.
    Graft harvest
    • I.
      With the patient's knee flexed 90°, perform a 3-cm long incision over the pes anserinus.
    • II.
      To protect the medial collateral ligament, elevate the sartorial fascia from proximal to distal with a blunt object.
    • III.
      Longitudinally incise the sartorial fascia and expose the gracilis and semitendinous tendons.
    • IV.
      Release the deep portion of the sartorial fascia with a blunt right-angle clamp.
    • V.
      Whip stitch the ends of both tendons.
    • VI.
      With a striper harvest the tendons from distal to proximal.
  • 4.
    Graft preparation
    • I.
      Remove muscle fibers and unstable portions from the grafts.
    • II.
      Measure the length of each tendon to plan the correct graft configuration.
    • III.
      Simulate the graft configuration to determine the appropriate length and diameter.
  • 5.
    Bone marrow cell harvest
    • I.
      Insert a 14-gauge trocar through the anteromedial portal.
    • II.
      Introduce the trocar 30 mm deep into the femoral notch apex.
    • III.
      Turn off the arthroscopic fluid.
    • IV.
      Remove the sty1et.
    • V.
      Discard the first milliliter of blood.
    • VI.
      With a 30-mL syringe preloaded with a heparinized solution slowly aspirate 60 mL of bone marrow.
  • 6.
    Biological augmentation
    • I.
      Under direct arthroscopic vision through the anteromedial portal, apply platelet-rich plasma at 7% to the tibial tunnel, the femoral tunnel, and the graft.
