The purpose of this study was to assess the outcome of arthroscopic double-bundle posterior cruciate ligament (PCL) augmentation using split Achilles allograft.
Prospective case series.
We analyzed 27 knees in 26 patients whose PCL had been augmented by the arthroscopic double-bundle technique using split Achilles allograft. There were 19 male and 7 female patients with a mean age of 27.9 years. Follow-up averaged 25 months (range, 12 to 48 months). The clinical results were evaluated according to the Lysholm knee scores. The posterior laxity was radiographically measured with differences of posterior tibial translation between the injured and the uninjured knee.
The Lysholm knee scores improved from 59.5 to 91.8 points (P < .05). The average radiographic side-to-side difference of the posterior tibial translation was 12.7 mm (range, 10 to 26 mm) preoperatively and 2.4 mm (range, 0 to 8 mm) at the time of the latest follow-up (P < .05). Eighteen knees (67%) had 0 to 2 mm translation, 6 knees (22%) had 3 to 5 mm, and 3 knees (11%) had 6 to 10 mm.
PCL injuries can be successfully treated with arthroscopic double-bundle augmentation using split Achilles allograft. This technique can preserve remnant fibers and restore both anterolateral and posteromedial bundles of the PCL.

本研究旨在评估采用跟腱异体移植片关节镜下双束后交叉韧带（PCL）增强术的疗效。
前瞻性病例系列研究。
我们分析了26例患者的27个膝关节，这些患者的PCL采用关节镜下双束技术并使用跟腱异体移植片进行了增强。其中男性19例，女性7例，平均年龄27.9岁。随访平均25个月（范围12至48个月）。根据Lysholm膝关节评分评估临床结果。通过测量受伤膝关节与未受伤膝关节之间胫骨后移的差异，以影像学方式评估后方松弛度。
Lysholm膝关节评分从59.5分提高到91.8分（P <.05）。术前胫骨后移的平均影像学双侧差异为12.7 mm（范围10至26 mm），最近一次随访时为2.4 mm（范围0至8 mm）（P <.05）。18个膝关节（67%）的移位为0至2 mm，6个膝关节（22%）为3至5 mm，3个膝关节（11%）为6至10 mm。
采用跟腱异体移植片关节镜下双束增强术可成功治疗PCL损伤。该技术可保留残留纤维并恢复PCL的前外侧束和后内侧束。
