BACKGROUND: The posterior cruciate ligament (PCL) is crucial to restrain the posterior translation of the tibia. Its anatomical structure is complex. A proper understanding of PCL anatomy may assist surgeon in reconstructing anatomically native PCL. AIM: To describe the anatomical numerical measurement of the PCL in Vietnamese adults. METHODS: Twenty-one fresh cadaveric knees were examined. The macroscopic details of the intra-articular PCL, the attachment of the anterolateral bundle (ALB), posteromedial bundles (PMB) to the femur and tibia were analysed. We used a digital camera to photograph the cadaveric specimens and used the ImageJ software to analyse the collected images. RESULTS: The ALB and PMB length were 35.5 ± 2.78 and 32.6 ± 2.28 mm, respectively. The smallest and the biggest diameter of middle third of the PCL were 5.9 ± 0.71 and 10.0 ± 1.39 mm, respectively. The area of cross section of middle third of the PCL was 53.6 ± 12.37 mm2. The femoral insertion area of ALB and PMB were 88.4 ± 16.89 and 43.5 ± 8.83 mm2, respectively. The distance from the central point of femoral ALB, PMB, and total PCL insertion to the Blumensaat line were 5.5 ± 0.91, 11.5 ± 1.98, and 7.6 ± 1.42 mm, respectively. The shortest distance from medial femoral cartilage rim to the central point of femoral ALB, PMB, and total PCL insertion were 7.0 ± 0.79, 7.3 ± 0.95, and 7.8 ± 1.73 mm, respectively. The tibial insertion area of ALB and PMB were 84.5 ± 12.52 and 47.8 ± 6.20 mm2 respectively. The shortest distance from the posterior cartilage corner of the medial tibial plateau to the central point of ALB, PMB, and total PCL insertion to tibia were 8.5 ± 1.02, 9.4 ± 1.11, and 8.3 ± 1.1 mm, respectively. The central point of tibial PCL insertion was 9.7±1.08 mm below cartilage plane of the medial tibial plateau. CONCLUSION: This study describes the detailed anatomical measurement of the PCL and its bundles in adults.

ObjectiveTo establish the radiographic distances from posterior cruciate ligament (PCL) tibial insertions centers to the lateral and medial tibial cortex in the anteroposterior view, and from these centers to the PCL facet most proximal point on the lateral view, in order to guide anatomical tunnels drilling in PCL reconstruction and for tunnel positioning postoperative analysis.Study designControlled laboratory study.MethodsTwenty cadaver knees were evaluated. The PCL's bundles tibial insertions were identified and marked out using metal tags, and the knees were radiographed. On these radiographs, the bundles insertion sites center location relative to the tibial mediolateral measure, and the distances from the most proximal PCL facet point to the bundle's insertion were determined. All measures were calculated using the ImageJ software.ResultsOn the anteroposterior radiographs, the mean distance from the anterolateral (AL) bundle insertion center to the medial tibial edge was 40.68 ± 4.10 mm; the mean distance from the posteromedial (PM) bundle insertion center to the medial tibial edge was 38.74 ± 4.40 mm. On the lateral radiographs, the mean distances from the PCL facet most proximal point to AL and PM bundles insertion centers were 5.49 ± 1.29 mm and 10.53 ± 2.17 mm respectively.ConclusionsIt was possible to establish a radiographic pattern for PCL tibial bundles insertions, which may be useful for intraoperative tunnels locations control and for postoperative tunnels positions analysis.

“…4 Em publicação recente foram descritas a localização anatômica e as medidas das inserç ões tibiais do LCP. 5 A localização inadequada dos túneis, na reconstrução do LCP, pode causar encurtamento ou alongamento do enxerto durante a flexão do joelho e insucesso ulterior. 6 Para que a função do ligamento reconstruído seja normal, a reconstrução anatômica de suas bandas anterolateral (AL) e posteromedial (PM) deve ser cogitada, já que estudos biomecânicos mostraram que a reconstrução do LCP com dupla banda é superior à reconstrução com banda única.…”

Desenho: Estudo laboratorial controlado. Métodos: Vinte joelhos de cadáveres foram avaliados. As inserç ões tibiais das bandas do LCP foram identificadas e demarcadas com marcadores metálicos e os joelhos foram radiografados. Nas radiografias determinamos a localização do centro de inserção das bandas relativa à medida mediolateral da tíbia e as distâncias do ponto mais proximal da faceta do LCP até o centro de inserção das bandas. Todas as medidas foram calculadas com o software ImageJ.Resultados: Nas radiografias em anteroposterior a distância média entre o centro da inserção da banda anterolateral (AL) até a borda medial da tíbia foi de 40,68 ± 4,10 mm; a distância entre o centro de inserção da banda posteromedial (PM) até a borda medial da tíbia foi, em média, de 38,74 ± 4,40 mm. Nas radiografias em perfil as distâncias médias entre o ponto mais proximal da faceta do LCP e os centros de inserção das bandas AL e PM foram de 5,49 ± 1,29 mm e 10,53 ± 2,17 mm, respectivamente.Conclusões: Foi possível estabelecer um padrão radiográfico das inserç ões tibiais das bandas do LCP que pode ser útil para o controle intraoperatório da localização dos túneis e para análise pós-operatória da posição dos túneis.
