N2  -  Summary. Background. Injections into the posterolateral corner (PLC) of the knee are effective for treating or diagnosing lateral and rotational knee pathologies. However, due to the intricate anatomy and proximity of neurovascular structures, precision is essential. This study aims to identify anatomically safe zones for PLC knee injections and evaluate dye distribution with respect to critical neurovascular structures. Methods. Ten cadaveric knees (5 left and 5 right) without pathological lesions were dissected in the Anatomy Laboratory of the Health Sciences University Gulhane Medical Faculty. Anatomical landmarks and the injection procedures were documented through video recording. Additionally, a topographic anatomy demonstration was performed using a volunteer who had provided informed consent. Results. The video recording clearly illustrated critical anatomical structures of the PLC and their relationships during injection procedures. In all 10 cadaver knees, targeted injections were completed without dye leakage toward vital neurovascular bundles such as the common peroneal nerve or vascular structures. This anatomical preservation was confirmed visually and documented. Topographic equivalents were also demonstrated on a volunteer with informed consent. No dye spread was observed toward critical neurovascular structures in any of the 10 specimens. Conclusions. PLC injections are high-precision procedures that require detailed anatomical knowledge. Mastery of key landmarks significantly improves the safety and effectiveness of the procedure.
