Previous study has shown a likely link between increased shoe- surface traction and risk of knee Anterior Cruciate Ligament (ACL) injury. Portable natural grass systems are being used more often in sport, but no study to date has investigated their relative safety. By their nature, they must have high resistance to falling apart and therefore newly laid systems may be at risk of creating excessive shoe-surface traction. This study describes two clusters of knee injuries (particularly non-contact ACL injuries), each occurring to players of one professional football team at single venue, using portable grass, in a short space of time. The first series included two ACL injuries, one posterolateral complex disruption and one lateral ligament tear occurring in two rugby league games on a portable bermudagrass surface in Brisbane, Australia. The second series included four non-contact ACL injuries over a period of ten weeks in professional soccer games on a portable Kentucky bluegrass/perennial ryegrass surface in Barcelona, Spain. Possible intrinsic risk factors are discussed but there was no common risk shared by the players. Although no measures of traction were made at the Brisbane venue, average rotational traction was measured towards the end of the injury cluster at Camp Nou, Barcelona, to be 48 Nm. Chance undoubtedly had a part to play in these clusters, but the only obvious common risk factor was play on a portable natural grass surface soon after it was laid. Further study is required to determine whether portable natural grass systems may exhibit high shoe-surface traction soon after being laid and whether this could be a risk factor for knee injury. Key pointsExcessive shoe-surface traction is a hypothesised risk factor for knee ligament injuries, including anterior cruciate ligament injuries.Portable natural grass systems (by their nature in order to prevent grass rolls or squares from falling apart) will tend to exhibit high resistance to tearing when first laid. This may lead to excessive shoe-surface traction.This dual case series describes two clusters of non-contact knee ligament injuries which occurred in circumstances of newly laid portable turf.Further research is warranted to undercover any link between non-contact knee ligament injuries and ground surfaces conditions.
先前的研究表明，鞋地表面摩擦力的增加与膝关节前交叉韧带（ACL）损伤的风险之间可能存在关联。便携式天然草皮系统在运动中越来越多地被使用，但迄今为止尚无研究调查它们的相对安全性。从本质上讲，它们必须具有高抗破裂性，因此新铺设的系统可能存在产生过高鞋地表面摩擦力的风险。本研究描述了两个膝关节损伤集群（特别是非接触性 ACL 损伤），每个集群都发生在一个职业足球队的球员身上，他们在短时间内在同一地点使用便携式草皮。第一个系列包括两个 ACL 损伤，一个后外侧复合体破裂和一个外侧韧带撕裂，发生在澳大利亚布里斯班的便携式百慕大草皮表面的两个橄榄球比赛中。第二个系列包括在西班牙巴塞罗那的便携式肯塔基蓝草/多年生黑麦草表面的职业足球比赛中，在十周的时间内发生了四个非接触性 ACL 损伤。讨论了可能的内在风险因素，但球员之间没有共同的风险。虽然在布里斯班场地没有进行牵引力测量，但在巴塞罗那诺坎普球场的伤病集群结束时测量到的平均旋转牵引力为 48 Nm。机会无疑在这些集群中发挥了作用，但唯一明显的共同风险因素是在刚铺设完的便携式天然草皮表面上进行比赛。需要进一步研究以确定便携式天然草皮系统在铺设后是否会立即表现出高鞋地表面牵引力，以及这是否可能成为膝关节损伤的一个风险因素。要点过度的鞋地表面牵引力是膝关节韧带损伤（包括前交叉韧带损伤）的一个假设风险因素。便携式天然草皮系统（为了防止草皮卷或草皮方块散开）在最初铺设时往往具有很高的抗撕裂性。这可能导致过高的鞋地表面牵引力。本双病例系列描述了两个非接触性膝关节韧带损伤集群，这些损伤发生在新铺设的便携式草皮场地的情况下。需要进一步研究以发现非接触性膝关节韧带损伤与地面条件之间的任何联系。
