2025年2月5日 · The ACL and PCL are two major ligaments that crisscross within the joint, allowing the knee to flex and extend without sliding back and forth. The ACL prevents the tibia (shin bone) from sliding in front of the femur (thigh bone) and gives rotational stability to the knee.

膝关节韧带损伤是膝关节中四个韧带中的一个或多个的扭伤， 内侧副韧带 （MCL），侧副韧带（LCL）， 后交叉韧带 （PCL）或 前十字韧带 （ACL）。 ACL，PCL，MCL和LCL损伤是由于膝盖扭曲或扭伤导致韧带过度拉伸或撕裂引起的。 你怎么能伤害你的膝盖？ 膝关节有四条韧带，稳定关节。 膝盖韧带的任何部位都可能因跑步，跳跃，扭曲或扭伤膝盖而受伤。 你可能听说有人撕裂他们的ACL，但这只是一个可能的膝盖韧带损伤，下面是你可能遭受的所有膝盖韧带损伤的 …

Together with the posterior cruciate ligament (PCL), the ACL guides the instantaneous center of rotation of the knee, therefore controlling joint kinematics. While the anteromedial bundle is the primary restraint against anterior tibial translation, the posterolateral bundle tends to stabilize the knee near full extension, particularly against ...

PCL Tear vs. ACL Tear: Key Differences. The PCL and ACL are crucial ligaments that stabilize the knee joint. The PCL (located at the back of the knee) prevents the shinbone from moving too far backward, while the ACL (at the front) prevents excessive forward movement of the shinbone. PCL tears are far less common than ACL tears. Causes

2025年3月18日 · ACL, MCL and PCL injuries are damage to ligaments that keep the knee from wobbling or giving out when you move. These ligaments are the anterior cruciate ligament (ACL), medial collateral ligament (MCL) and posterior cruciate ligament (PCL). When the knee is forced into an unusual position, 1 or more of the ligaments can tear, either part way ...

2023年11月17日 · The anterior cruciate ligament is one of the two cruciate ligaments that aids in stabilizing the knee joint. It is the most commonly injured ligament in the knee, commonly occurring in football, soccer, and basketball players.

PCL tears typically occur when there is a direct blow to the front of the tibia, or when the knee hyperextends from an awkward landing. While both ACL and PCL tears can be painful initially, the real problem is the lingering instability of the knee joint.

2025年3月21日 · The ACL crosses the posterior cruciate ligament (PCL) and attaches to the anterior aspect of the tibial plateau after passing diagonally downward and forward through the middle of the knee joint from its origin. The top portion of the knee joint is made up of the tibial plateau, which is the flat upper surface of the shin bone (tibia). ...

2025年3月26日 · Compared to injuries to the anterior cruciate ligament (ACL), the knee’s more vulnerable counterpart, the posterior cruciate ligament injuries (PCL injuries) occur much less frequently. Your thigh bone (femur) and shinbone (tibia) are joined by the ACL and posterior cruciate ligament.

Two of the most frequently discussed types of knee injuries are Anterior Cruciate Ligament (ACL) injuries and Posterior Cruciate Ligament (PCL) injuries. While both of these ligaments play crucial roles in knee stability, their injuries present different …
