Accurate Measurement in All-inside Posterior Cruciate Ligament Reconstruction: A Technical Note

With the increasing rate of posterior cruciate ligament reconstruction (PCLr) and growing adoption of the all-inside PCLr, the existing literature lacks an optimal surgical protocol for this technique. It is well recognized that variations in knee size and intraoperative positioning pose challenges in determining the key parameter-the length of the intra-articular graft. Our technique describes an intraoperative measurement for all-inside PCLr, specifically addressing the critical issue of imprecise graft and socket sizing. All patients achieved immediate knee stability, with negative intraoperative posterior drawer tests. This reproducible technique reduces the risk of surgical failure, and provides a practical solution for optimizing outcomes of all-inside PCLr.
