Introduction:
We present the surgical technique for arthroscopic revision posterior cruciate ligament (PCL) reconstruction with use of the modified tibial-inlay double-bundle method without a change of the patient's position from supine to prone.
Step 1 Graft Preparation:
Create the Achilles tendon allograft as a tibial bone block with two femoral bundles.
Step 2 Patient Position:
With the patient in the supine position, flexion, abduction, and external rotation of the hip and flexion of the knee 60° to 90° can provide easier access to the popliteal area.
Step 3 Femoral Tunnel Preparation:
Make anterolateral and posteromedial femoral tunnels in a shallow-shallow position using an outside-in technique for the anterolateral bundle and the inside-out technique for the posteromedial bundle.
Step 4 Tibial Tunnel Preparation:
Make the tibial tunnel with the patient supine with the hip flexed, abducted, and externally rotated and the knee flexed 60° to 90° to provide easier access to the popliteal area.
Step 5 Graft Passage:
Using a wire loop, pass the graft through the knee joint posterior to the intercondylar notch into the femoral tunnel.
Step 6 Graft Fixation:
Use a cannulated screw with a spiked washer to secure fixation of the bone block to the tibia.
Step 7 Postoperative Rehabilitation:
Rehabilitation after a PCL repair is generally more conservative than the accelerated rehabilitation used after an ACL repair.
Results:
In our study, twenty-two patients (twenty men and two women; mean age, 37.4 years) were treated with revision PCL reconstruction performed with the described technique and followed for a mean of 39.6 months (range, twenty-four to seventy-two months)14.IndicationsContraindicationsPitfalls & Challenges.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Modified Boxplots
However, the box plot does not tell the reader about outliers - values that lie far from the center of the data. We can modify the standard box and whisker plot to identify the outliers and visualize the actual spread of the data in a sample.
Initially, we calculate the adjusted...
