Anatomical Relationship Between the Distal Lateral Femoral Cutaneous Nerve and the Quadriceps Tendon Autograft Harvest Site: A Cadaveric Study

This dataset accompanies the study titled “Anatomical Relationship Between the Distal Lateral Femoral Cutaneous Nerve and the Quadriceps Tendon Autograft Harvest Site: A Cadaveric Study.” It contains quantitative measurements of the spatial relationship between the distal lateral femoral cutaneous nerve (LFCN) and predefined quadriceps tendon (QT) landmarks relevant to anterior cruciate ligament (ACL) reconstruction. Measurements were obtained from 29 embalmed adult cadaveric lower extremities (13 male, 16 female). For each specimen, the shortest linear distance (in millimeters) was recorded between the most distal identifiable branch of the LFCN and five QT regions: superior, inferior, medial, lateral, and central. All measurements were performed using digital calipers and averaged across repeated trials to minimize observer variability. The dataset also includes specimen-level demographic variables such as sex, laterality, and height (when available). These variables were used to assess potential associations with LFCN–QT distance using statistical methods including one-way ANOVA, two-way ANOVA, and ANCOVA. This dataset was generated to characterize anatomical variation in the distal course of the LFCN and to identify regions of increased risk for iatrogenic nerve injury during quadriceps tendon autograft harvest. The data support findings of region-specific variability and sex-based differences in nerve proximity, with potential implications for surgical planning and risk reduction. All measurements are reported in millimeters (mm). Variable definitions and coding are provided in the accompanying data dictionary file. No identifiable human subject information is included.
