Double-bundle anterior cruciate reconstructions have led to an increased interest in quantifying anterolateral rotatory stability. The application of combined internal rotation and valgus torques to the knee can more nearly recreate the anterolateral subluxation that occurs in the pivot shift test in vitro compared to coupled internal rotation torque and anterior tibial loads.
Purpose: The purpose of this study was to evaluate the risk of tunnel collisions of the fibular collateral ligament (FCL) and posterolateral bundle anterior cruciate ligament(PLB-ACL) tunnels during a combined FCL and doubledundle (DB) ACL reconstruction.
Methods: Thirty-six 4th-generation synthetic femurs (Sawbones, Pacific Research Laboratories, Vashon, WA) were utilized, and two different femur sizes were […]
The purpose of this study was to establish quantitative and qualitative radiographic landmarks for ntifying the femoral and tibial attachment sites of the AM and PL bundles of the native ACL and to assess the reproducibility of identification of these landmarks using intraclass correlation coefficients. It was hypothesized that the radiographic positions of the […]
Quantification of the overall anterior cruciate ligament (ACL) and anteromedial (AM) and posterolateral (PL) bundle centers in respect to arthroscopically pertinent bony and soft tissue landmarks has not been thoroughly assessed.
Ligament restraints to terminal knee extension are poorly understood.
The efficacy of single-bundle versus double-bundle ACL reconstruction in improving knee stability has been widely discussed. The biomechanics of all-inside double-bundle ACL reconstructions have not been evaluated.
Double-bundle anterior cruciate ligament (ACL) reconstructions involve drilling 2 tibial tunnels separated by a narrow 2-mm bone bridge. The sequence of reaming and drilling the tibial tunnels for double-bundle ACL reconstructions has not been defined.
Effective soft tissue graft fixation to the tibial tunnel in all-inside anterior cruciate ligament reconstructions has been reported to be a problem and may lead to retrograde pullout at ultimate load testing.
Chondrocalcinosis, although very rare in young adults, can occur in some young patients. Although its presenting clinical history or radiographic findings may resemble those of an intraarticular loose body, chondrocalcinosis can occur in young athletes, possibly after repetitive microtrauma, and should be included in the differential diagnosis of calcified […]
Posterolateral corner injuries can be difficult to diagnose. The external rotation recurvatum test was one of the first clinical tests described to diagnose these injuries. Since its earliest description, it has been reported that a positive test result occurred with posterior translation of the proximal tibia with respect to the distal femur as the […]
