“…However, the rotatory movement we report was not detected with the radiographic techniques used by others. Logan et al compared the kinematics of PCLdeficient knees with normal knees using a vertical open MRI system [12]. They reported 0.5 mm medial and 1.9 mm lateral displacement with manual posterior stress in six intact knees, the contralateral side of the PCL-deficient knees, at a flexion angle of 90°.…”

Background Deep knee flexion is important to proper function for some activities and in some cultures, although there are large posterior forces during high knee flexion. Most of what we know about posterior restraint and stability, however, has not been determined from deep flexion and without distinguishing motion in the medial and lateral compartments. Questions/purposes We therefore evaluated (1) the difference in posterior displacement between the medial and lateral compartments at a commonly used flexion angle of 90°; (2) that of deeply flexed knees at 135°; and (3) the difference in kinematics in the medial and lateral compartments. We analyzed posterior stability in 21 normal knees using interventional open magnetic resonance imaging (MRI) system.

“…It is now generally accepted that patients with isolated PCL injuries with greater than 10 mm of posterior laxity or high-grade PCL injuries associated with multiligamentous knee injuries have improved subjective outcomes, side-to-side differences in stability, and decreased laxity on stress radiographs with operative intervention [5,11,13,23,25,36,39,45,47,54]. This may be the result of restoration of normal knee kinematics and a decreased propensity to develop medial compartment and patellofemoral compartment arthrosis [7,19,26,28,46,51]. Despite the demonstrated benefit of operative intervention, debate remains over the most advantageous operative technique.…”

Background All-arthroscopic tibial inlay double-bundle (DB) posterior cruciate ligament (PCL) reconstruction avoids an open dissection and the ''killer turn'' while maintaining the advantage of an anatomic graft. However, clinical data on the viability of this surgical technique in multiligamentous knee injuries are lacking. Questions/purposes At greater than 2 years of followup, we evaluated (1) validated outcomes scores; (2) range of motion; and (3) side-to-side stability on PCL stress radiographs of a small group of patients who underwent all-arthroscopic tibial inlay DB PCL reconstruction in multiligamentous knee injuries, either shortly after injury or late.

“…In literature, surgical indications for PCL injuries treatment remain controversial, but in PCL avulsion, surgical reinsertion of the avulsioned fragment is a recommended procedure 5,6 . Posterior cruciate ligament rupture leads to an increase in the passive sagittal laxity of the medial compartment of the knee so alters the kinematics of the medial compartment of the k nee, resulting in " •xed" anterior subluxation of the medial femoral condyle (posterior subluxation of the medial tibial plateau) 7 . This results in development of osteoarthritis in medial compartment in patients with chronic posterior instability, so necessitates the repair or reconstruction of the injured PCL.…”
