Abstract：
OBJECTIVE: To determine bony knee morphological factors associated with primary posterior cruciate ligament (PCL) rupture or PCL graft failure after PCL reconstruction.
METHODS: Three databases, namely MEDLINE, PubMed and EMBASE, were searched on 30th May 2023. The authors adhered to the PRISMA and R-AMSTAR guidelines as well as the Cochrane Handbook for Systematic Reviews of Interventions. Data such as receiver operating characteristic curve parameters, as well as p-values for comparisons of values between patients with PCL pathology and control patients, were recorded.
RESULTS: Nine studies comprising 1054 patients were included. Four studies reported that patients with PCL injury had flatter medial posterior tibial slopes (MTS) than controls, with mean values of 4.3 (range: 3.0-7.0) and 6.5 (range: 5.0-9.2) degrees, respectively. Two studies reported an MTS cutoff value ranging below 3.90-3.93° being a significant risk factor for primary PCL rupture or PCL graft failure. Two studies reported that shallow medial tibial depths were associated with primary PCL rupture, with mean values of 2.1 (range: 2.0-2.2) and 2.6 (range: 2.4-2.7) mm in PCL injury and control groups, respectively. Stenotic intercondylar notches and femoral condylar width were not consistently associated with PCL injuries.
CONCLUSIONS: Decreased MTS is associated with primary PCL rupture and graft failure after PCL reconstruction with values below 3.93° being considered as a significant risk factor. Less common risk factors include shallow medial tibial depth, while femoral condylar width and parameters with regards to the intercondylar notch, such as notch width, notch width index and intercondylar notch volume, demonstrated conflicting associations with primary or secondary PCL injuries.
METHODS: Level III.

摘要：
目的：确定与原发性后交叉韧带（PCL）断裂或PCL重建后移植失败相关的骨性膝关节形态学因素。
方法：三个数据库，即MEDLINE,PubMed和EMBASE,在2023年5月30日进行了搜索。作者遵守PRISMA和R-AMSTAR指南以及Cochrane干预措施系统审查手册。接收器工作特性曲线参数等数据，以及PCL病理患者和对照患者之间的p值比较，被记录下来。
结果：纳入了包括1054名患者的9项研究。四项研究报告，PCL损伤患者的胫骨后内侧斜坡（MTS）比对照组更平坦，平均值为4.3（范围：3.0-7.0）和6.5（范围：5.0-9.2）度，分别。两项研究报告，MTS截止值低于3.90-3.93°是原发性PCL破裂或PCL移植物失败的重要危险因素。两项研究报道，胫骨内侧浅深度与原发性PCL破裂有关，PCL损伤组和对照组的平均值分别为2.1（范围：2.0-2.2）和2.6（范围：2.4-2.7）mm，分别。狭窄的髁间凹口和股骨髁宽度与PCL损伤并不一致。
结论：MTS降低与PCL重建后原发性PCL破裂和移植物衰竭相关，低于3.93°的值被认为是一个显著的危险因素。较不常见的危险因素包括浅的胫骨内侧深度，而股骨髁宽度和有关髁间切迹的参数，如缺口宽度，凹口宽度指数和髁间凹口体积，显示与原发性或继发性PCL损伤有冲突的关联。
方法：三级。
