The “all-inside” approach establishes bone sockets for anterior cruciate ligament reconstruction (ACLR) or posterior cruciate ligament reconstruction (PCLR) graft passage on both the tibial and femoral sides, in contrast to conventional full bone tunnels. This is often accomplished by making use of suspensory fixation rather than fixation with screws for graft stabilisation. The All Inside approach can be utilised with all soft tissue or bone plug grafts, whether autografts or allografts, such as the hamstring tendon, quadriceps tendon, bone patellar tendon bone (BPTB), or peroneus tendon grafts. The advantages encompass typically a singular hamstring graft, anatomical socket placement, reduced implants, suitable graft tensioning and retensioning, and circumferential graft-to-bone healing. The All Inside method is beneficial for children with an open physis. Strategies for effective all-inside surgery encompass aligning graft socket dimensions and ensuring the requisite length for graft placement to avert “bottoming out,” as well as verifying cortical button fixation intraoperatively on both the femoral and tibial sides. Complications may encompass graft-socket incongruence, unexpected full tunnel reaming, and loss of cortical fixation. Numerous investigations have demonstrated that the all-inside technique has comparable biomechanical features and clinical effects to the conventional full-tunnel techniques. In contrast to anterior cruciate ligament reconstruction (ACLR), which is among the most often performed arthroscopic ligament reconstructions, posterior cruciate ligament reconstruction (PCLR) remains a demanding arthroscopic surgical technique. Negotiating the so-called killer turn during arthroscopic PCL reconstruction can be quite challenging.
