Popis: Objectives The arthroscopic “lateral gutter drive‐through” (LGDT) sign is reported to diagnose popliteus tendon (PT) injury with high sensitivity and specificity. However, no study has provided a postoperative evaluation of combined posterior cruciate ligament (PCL) and posterolateral corner (PLC) injuries using the LGDT test. Methods From January 2012 to January 2015, a total of 80 consecutive patients who underwent combined PCL reconstruction and PLC surgeries were identified. Fifty eligible patients were included in this study for evaluation with subjective scoring systems, physical examinations, posterior and varus stress radiographs, and second‐look arthroscopic surgeries during hardware removal operation. Results Forty‐nine patients were available for a mean of 31.5 ± 9.3 months follow‐up (range, 24.0–81.0 months). In terms of PLC injury pattern, there were 27 type A, 10 type B, and 12 type C patients, with 21 acute cases and 28 chronic cases. At the final follow‐up, subjective scores were all significantly improved. The side‐to‐side difference (SSD) of posterior tibial translation (PTT) improved from 18.4 ± 9.2 mm (range, 12.9–25.6 mm) to 5.2 ± 5.0 mm (range, −5.0−18.5 mm, P
