The Kawano reconstruction technique is an interesting alternative in cases of missing autografts. Read Paper. secondary restraint to posterolateral rotation with <50 flexion. Previous studies have shown that reconstruction of the PLC of the knee leads to superior outcomes compared with simple repair. We describe a new reconstructive technique for PLC based on Larson's method, which reflects the physiological load-sharing pattern of the lateral collateral ligament (LCL) and popliteofibular ligament (PFL). Isometry of the lateral collateral and popliteofibular ligaments and techniques for reconstruction using a free semitendinosus tendon graft. approach. Acute reconstruction is thought to be an effective treatment option for PLC injuries with irreparable soft tissue. The minimally invasive technique introduced is performed through the postero-pateral corner (PLC) of the knee to reconstruct the posterolat-eral rotary instability (PLRI) of the knee. In Larsons technique there is reconstruction of the fibular collateral ligament and popliteo fibular ligament. We would like to show you a description here but the site wont allow us. 10,11 in the larson technique, which is a fibulofemoral-based technique, reconstruction is less technically demanding and offers encouraging clinical results, but since it is not anatomical, it has less posterior stabilization and therefore is not suitable LCL +/- PLC reconstruction. Early reconstruction techniques for PLC injuries applied a single femoral fixation site and a fibular sling ( 23 ). goal is to reconstuct LCL and the popliteofibular ligament using a free tendon graft (semitendinosus or achilles) fibular-based reconstruction (Larson) An approximated isometric technique, tubercle. Injuries to the posterolateral corner can be debilitating to the person and require recognition and treatment to avoid long term consequences. Reconstruction of PLC was performed according to the Schechinger modification of the Larson technique. techniques that have enhanced clinical outcomes.1-3) How-ever, the most effective arthroscopic PCL reconstruction method has not been definitively determined, and some controversy remains as to whether to employ a single or double femoral tunnel, a 1- or 2-incision technique, and a transtibial tunnel or tibial inlay technique.3-5) Further- In Larsons technique there is reconstruction of the fibular collateral ligament and popliteo fibular ligament. A semitendinosus autograft may also be used if not being used for other reconstructive purposes. Conclusion: Reconstruction of multi-ligament knee injury shows a good outcome than it was left alone. provides 69% of restraint at 30. Larsons sling procedures - Larsons PLC reconstruction aims to restore the functions of the PFL and the LCL.

Diagnosis can be suspected with a knee effusion and a positive dial test but MRI studies are required for confirmation. Our hypothesis was that both the groups will have similar improvements after surgery. Larsons reconstruction and LaPrades reconstruction techniques were done and the clinical outcomes were analyzed. The PLC lesion was managed with a reconstruction of both LCL and PT with an allograft in 66 (25.4%) patients. Its assessment and proper diagnosis are keys in the context of a PLC reconstruction, since reconstruction techniques use a tunnel at the fibular head level. It is important to evaluate the biomechanical properties of these reconstruction techniques under simulated The original Larson's technique shows good outcome for non athlete patients in Hospital Pakar Sultanah Fatimah, Muar. There have been many techniques describing reconstructions of the PLC. Two-incision technique: one over the fibular head, one over the lateral epicondyle. 2).
