“…A maximum pressure load of 250 N was used in the clinical study of ACL tears and 200 N of pressure load was considered to be the threshold necessary to obtain good reproducibility of measurements in injured knees [6]. Di Iorio et al [8], Lorbach et al [9], and Morice et al [10] applied a maximum pressure load of 134 N while Vauhnik et al [11,12], Beldame et al [13], Jenny and Arndt [14] and Pierrat et al [15] applied a maximum pressure load of 250 N.…”

“…Clinically, the pivot shift phenomenon may be difficult to detect, especially in a situation of pain from an acute ACL tear and subsequent contraction of muscles, which can inhibit the subluxation phenomenon. Additionally, due to improving technologies, such as navigation and sensors, new techniques and tools have been developed to quantify clinical pivot shift kinematics [30][31][32] . Although the pivot shift seems more complicated to evaluate compared to the ATT, studies report its strong correlation to clinical outcomes [33] .…”

ligament (ACL) on kinematics and clinical outcomes have been investigated in many biomechanical and clinical studies over the last several decades. The knee is a complex joint with shifting contact points, pressures and axes that are affected when a ligament is injured. The ACL, as one of the intra-articular ligaments, has a strong influence on the resulting kinematics. Often, other meniscal or ligamentous injuries accompany ACL ruptures and further deteriorate the resulting kinematics and clinical outcomes. Knowing the surgical options, anatomic relations and current evidence to restore ACL function and considering the influence of concomitant injuries on resulting kinematics to restore full function can together help to achieve an optimal outcome.

See: http://creativecommons.org/ licenses/by-nc/4.0/ [1] . The ACL is a central ligament of the knee. The main functional role of the ACL is to provide stability against anterior tibial translation (ATT) and internal rotation. An acute ACL rupture is a common orthopedic trauma, with an estimated incidence of 78 per 100000 persons and a mean age of 32 years in Sweden and an estimated incidence of up to 84 per 100000 persons in the United States [2,3] . A common and frequent injury mechanism is noncontact combined valgus-and internal-rotation trauma [2,4] . Therefore, ACL injuries are often associated with other ligamentous injuries, such as a (partial) rupture of the medial collateral ligament (MCL) or the menisci. In addition, compression of the lateral condyle with a bone bruise or chondral lesion is often associated with the injury due to the valgus trauma. Persistent instability of the knee may be associated with long-term degenerative lesions. Surgical treatment of the ACL in the context of other injured structures and reconstruction of the intact joint kinematics are suggested to be the keys to a good clinical outcome [5,6] . ANATOMYThe ACL has its origin at the medial area of the lateral femoral condyle and inserts into the center of the eminentia of the tibia plateau next to the anterior horn of the lateral meniscus. The structure of the ACL has been described as two functional bundles: The anteromedial (AM) and the posterolateral (PL) bundle [7] . These two bundles have been associated with different roles in anteroposterior and complex-rotational stabilization of the joint [8][9][10] . The femoral origin was described as oval shaped with a longitudinal diameter of 18 mm and a width of approximately 11 mm [11,12] . ...

“…The results revealed a negative pivot shift (33) or glide (16) in 49 patients with 12 of 16 (75%) patients having also a pivot glide on the healthy contralateral side; Lachman tests were negative in 50 cases. The IKDC score was classified according to category A in 44 patients (85%), B in 5 patients (9.6%), and C in 3 patients (5.8%).…”
