The Transportal Graft Passage in Transtibial Posterior Cruciate Ligament Reconstruction With a Bone-Patellar Tendon-Bone Graft.

ABSTRACT: Posterior cruciate ligament injury is one of the most common problems in sports medicine. The treatment of choice for this injury is posterior cruciate ligament reconstruction, which improves the biomechanical and clinical stabilities of the knee. There are many graft choices, of which the bone-patellar tendon-bone (BPTB) graft is a popular option. In applying the BPTB graft, most surgeons use the transtibial technique by passing the graft from the tibial tunnel to the femoral tunnel, which is normally performed without problems, but there is a chance of patellar tendon fiber damage because of the sharp turn required from the tibial tunnel to the femoral tunnel. To minimize this risk, herein we propose a transportal graft passage technique with which it is easy to pass the BPTB graft and reduce the risk of graft damage.

Project description:PurposeTo establish correlations between the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and patellar tendon in normal pediatric knees to inform surgical planning for ACL reconstruction graft size.MethodsMagnetic resonance imaging scans of patients ages 8 to 18 years were assessed. Measurements included ACL and PCL length, thickness, and width, and ACL footprint thickness and width at the tibial insertion. Interrater reliability was assessed with a random set of 25 patients. Pearson correlation coefficients were used to assess the correlation between ACL, PCL, and patellar tendon measurements. Linear regression models were used to test whether the relationships differed by sex or age.ResultsMagnetic resonance imaging scans of 540 patients were assessed. Interrater reliability was high for all measurements except PCL thickness at midsubstance. Sample equations for estimating ACL size are as follows: ACL length = 22.61 + 1.55∗PCL origin width (R2 = 0.46; 8- to 11-year-old male patients), ACL length = 12.37 + 0.58∗PCL length + 2.29∗PCL origin thickness - 0.90∗PCL insertion width (R2 = 0.68; 8- to 11-year-old female patients), ACL midsubstance thickness = 4.95 + 0.25∗PCL midsubstance thickness + 0.04∗PCL insertion thickness - 0.08∗PCL insertion width (R2 = 0.12; 12- to 18-year-old male patients), and ACL midsubstance width = 0.57 + 0.23∗PCL midsubstance thickness + 0.07∗PCL midsubstance width + 0.16∗PCL insertion width (R2 = 0.24; 12- to 18-year-old female patients).ConclusionsWe found correlations between ACL, PCL, and patellar tendon measurements that can be used to create equations that predict ACL size in various dimensions based on PCL and patellar tendon measurements.Clinical relevanceThere is a lack of consensus on the ideal ACL graft diameter for pediatric ACL reconstruction. The findings from this study can assist orthopaedic surgeons to individualize ACL graft size for specific patients.
