Several techniques for posterolateral corner reconstruction have been described in the literature, typically using allogeneic tissue. Autograft reconstruction has potential value because of decreased cost and limited allograft supply in some locations. Initial results of this hamstring autograft tendon technique are promising, but further research is needed to directly compare reconstruction graft sources. See related article on page 1676 I n this month's journal, Franciozi, Albertoni, Kubota, Abdalla, Luzo, Cohen, and LaPrade present the results of a novel technique for posterolateral corner (PLC) reconstruction with their article, "A Hamstring-Based Anatomic Posterolateral Knee Reconstruction With Autografts Improves Both Radiographic Instability and Functional Outcomes." 1 Their technique uses hamstring autograft for anatomic reconstruction in patients with chronic grade III PLC deficiency. 2 The authors report improved clinical and radiographic success, with significant improvement in Lysholm, International Knee Documentation Committee, and Tegner subjective scores, varus stress radiography, external rotation (dial test), and recurvatum deformity compared with preoperative measurements. The study cohort included 29 patients who underwent hamstring-based PLC reconstruction an average of 8.8 months after injury, with 2-to 5-year follow-up. Four of the 29 patients underwent a first-stage proximal tibial osteotomy to correct double or triple varus. All patients had complete disruption of the PLC, including the fibular collateral ligament, popliteofibular ligament, and popliteus tendon. There were no cases of isolated PLC
