The anterior cruciate ligament (ACL) connects the femur to the tibia and stabilize the knee join. The ACL resists anterior translation of the tibia relative to the femur; it also resists rotation. The cruciate ligaments are named according to their attachment on the tibia: the ACL courses from the posterior aspect of the intercondylar notch on ...
The anterior cruciate ligament originates at the medial wall of the lateral femoral condyle and inserts into the middle of the intercondylar area. It contributes significantly to the stabilization and kinematics of the knee joint. The femoral origin is oval and is located in the posterior aspect of the lateral femoral condyle.
Mar 09, 2016· Introduction. Anterior cruciate ligament (ACL) reconstruction is the sixth most common procedure performed in orthopaedics, and it is estimated that between 75,000 and 100,000 ACL repair procedures are performed annually in the United States alone. 1, 2 The ACL has therefore been intensively studied, and outcomes of ACL surgery have received considerable attention.
Feb 11, 2021· The anterior cruciate ligament secondary function is to resist tibial rotation and varus-valgus angulation at full extension. The anterior cruciate ligament has proprioceptive function, as evidenced by the presence of mechanoreceptors in the ligament…
Intra-articular landmarks for anterior cruciate ligament reconstructions R eview PL origin is located anterior and inferior relative to the AM origin when viewed arthroscopically (Figure 2B) [11]. Numerous cadaveric and radiologic studies have been performed to describe the localiza-tion of the attachment sites of the ACL with respect to ...
Aug 21, 2017· Anterior Cruciate Ligament Anatomy Historical Descriptions . The earliest known descriptions of the human ACL were made around 3000 bc and written on an Egyptian papyrus scroll. During the Roman era, Claudius Galen of Pergamon (199–129 bc ) described the ligaments of the knee and termed the ACL as “ligamenta genu cruciate.”In 1543 Andreas Vesalius completed the first …
(OBQ11.215) A 25-year-old male is one year status post anterior cruciate ligament (ACL) reconstruction using patellar bone-tendon-bone (BTB) autograft. He complains of persistent instability with certain activities. His operative dictation notes excellent stability intra-operatively with femoral fixation at the 12 o'clock position.
Partial tears of the anterior cruciate ligament (ACL) are common. The prognosis of a partial ACL tear is controversial and is dependent on the extent of the partial tear and associated meniscal, ligamentous, and osteochondral injuries. Small tears involving less than 25% of the ACL cross-section have a favorable prognosis of healing while ...
Start studying Hip Muscles Origin & Insertion. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Search. ... Anterior Cruciate Ligament (ACL) Origin lateral condyle femur insertion anterior tibial spine. Posterior Cruciate Ligament (PCL) Origin medial femoral condyle insertion posterior tibia.
Aug 05, 2010· The anterior cruciate ligament (ACL) is frequently injured and has limited potential to heal. 1-3 As such, surgical reconstruction using soft tissue autografts is often performed for active patients. 4-6 However, long‐term follow‐up studies revealed that 20–25% of patients have less than satisfactory results, with pain, loss of range of motion, and other …
Oct 24, 2016· Partial tear of the anterior cruciate ligament (ACL) involving more than 75 % of the distal ligament thickness in a 19 year old male. Sagittal T2-weighted FSE fat-suppressed image shows diffuse high-intensity changes (arrow) which involve the entire posterolateral bundle and partially the anteromedial bundle at the tibial insertion of the ligament
Background: The central intercondylar ridge (CIR) is an anatomical bony landmark that bisects the slope of the medial intercondylar ridge (MIR) between the tibial insertion of the anterior cruciate ligament (ACL) and anterior horn of lateral meniscus (AHLM) and was recently revealed by computed tomography (CT) evaluation corresponding to histologic slices of cadaveric knees.
Feb 21, 2021· The word cruciate means ‘cross’; here, the term ‘cross’ signifies that a cruciate ligament forms an ‘X’ shape which means one ligament (ACL) crosses over another ligament(PCL). There are two cruciate ligaments present in the knee joint: the anterior cruciate ligament (ACL) and the other being the posterior cruciate ligament (PCL).
Jul 01, 2008· An estimated 80 000 anterior cruciate ligament (ACL) injuries occur annually in the United States,1 and ACL-injured people often suffer long-term complications, such as meniscal lesions, impairment of normal knee function, and arthrofibrosis.2–4 These complications and the extended time loss from sport participation can be major setbacks for athletes.
Recently, the interest in surgical techniques that reconstruct the anteromedial (AM) and the posterolateral (PL) bundles of the anterior cruciate ligament (ACL) has risen. This review focuses on the structural as well as the mechanical properties of the ACL and the anatomical details of the femoral origin, midsubstance, and tibial insertion of ...
Jul 28, 2008· The anterior border of the femoral anterior cruciate ligament origin is Resident's Ridge. The ridge between the medial and lateral intercondylar tubercles at the base of the tibial eminence is the posterior margin of the anterior cruciate ligament on the tibia.

For both anterior cruciate ligament ganglia and mucoid degeneration, both bundles of the ligament had to be seen as intact from origin to insertion to exclude partial tears. These imaging criteria for anterior cruciate ligament ganglion and mucoid degeneration were based on prior reports with MRI and histology correlation [6–9].
Cadaveric anterior cruciate ligament origin and insertion. noncontact injury happens when the patient sustains a twisting or cutting motion through the knee with the foot planted. Direct contact injury occurs from a blow directly to the knee usually from a lateral or anterior direction (see Figure 5 ). Noncontact and direct contact
Oct 15, 2013· Origin and Insertion Points of the Anterior Cruciate Ligament. The bottom of the femur consists of the medial and lateral femoral condyles, circular bony protuberances that are separated by an intercondylar notch.
The anterior cruciate ligament (ACL) is one of the two cruciate ligaments that stabilize the knee joint. Gross anatomy The ACL arises from the anteromedial aspect of the intercondylar area on the tibial plateau and passes upwards and backwards...
