  • Posterolateral instability of the knee occurs more commonly in association with an injury to anterior and posterior cruciate ligament and combined injuries are severe injuries that result in significant functional instability and articular cartilage degeneration. Reconstruction of the anterior and posterior cruciate ligament without an appropriate treatment of posterolateral corner injury result in failure of the reconstructed cruciate ligaments. Meticulous physical examinations, imaging studies, lower limb alignment and gait pattern should be evaluated. Acute grade III isolated or combined injury of the posterolateral corner is best treated within three weeks by direct repair, or augumentation, or reconstruction. The appropriate surgical method or combined methods are selected among the several methods of posterior and posterolateal reconstruction, and all injuried posterolateral and cruciate ligament structures are anatomically reconstructed simultaneously or by stages. If a varus alignment and varus thrust is disclosed in chronic posterolateral instability of knee, soft tissue reconstructions laterally are highly unlikely to be able to correct tile problem. It is appropriate that valgus osteotomy should be done before soft tissue reconstruction and reevaluate the posterolateral instability about 6 months later.

  • Recurrent dislocation of elbow joint occurs relatively rarely by the injury of the collateral ligament which contributes elbow joint stability. Among them, posterolateral rotatory instability occurs by the injury to the lateral ulnar collateral ligament. We experienced a case of recurrent dislocation of elbow joint due to posterolateral rotatory instability. We treated operatively with lateral ulnar collateral ligament reconstruction using the palmaris longus tendon by technique of Nestor et al. We report it with literature analysis.

Effect of Lateral and Posterior Placement of Single-Bundle and Double-Bundle ACL Reconstructions on Tibial Internal Rotation During Single-Leg Landing (전방십자인대 한다발재건술의 후외측다발 재건 및 두다발재건술이 외발착지 동작 시에 경골내회전에 미치는 영향)

  • Anterior cruciate ligament (ACL) injuries are treatedwith surgical reconstruction. Although ACL consists of two functional bundles, only the anteromedial bundle is surgically reconstructed, and the effect of the reconstruction of the posterolateral bundle is unknown. The purpose of this study is to investigate the role of the posterolateral bundle and the effect of double-bundle reconstruction during single-leg landing. A 3D dynamic knee with various ACL reconstructed models was created using MRI, and single-leg landing motion was simulated using in-vivo human experimental data. The results showed that the lateral shift of the tibial insertion of the anteromedial bundle and the posterolateral bundle of the ACL constrain the tibial internal rotation more efficiently than a single anteromedial bundle can. In addition, double-bundle ACL reconstruction is less sensitive to inaccuracies in the tibial tunnel placement.

  • Posterolateral rotatory instability is the most common pattern of elbow instability especially which is recurrent, and is usually post-traumatic because of inadequate soft tissue healing. The lateral ulnar collateral ligament was reconstructed by using ipsilateral palmaris longus tendon. Functionally good result was obtained. This is a case report illustrating the posterolateral rotatory instability of the elbow and its reconstruction with palmaris longus.

  • Injury of posterolateral corner is unusual, but it can cause disability due to severe instability and cartilage damage. However, the anatomical structures, diagnosis and treatment have not defined clearly yet. Posterolateral corner injury is regarded as the one of main factor to the results of failure in cruciate ligament reconstcution if it was undiagnosed and untreated. Diagnosis of postetolateral corner injury is consists of physical exam, radiographic finding, MRI, and arthroscopic findings. The treatment method of of postetolateral corner injury depends on the time and severity of injury. Anatomical reconstruction of posterolateral corner shows the better clinical outcome than non anatomical reconstructions, but the clinical results of long term follow up is still needed. Therefore, the aim of this article is to review the recent literatures and to organize diagnosis and treatment of posterolateral corner injury.

  • Posterolateral instability of the knee is known as one of the most challenging injuries . Although several procedures have been designed for the posterolateral instability, there is no gold standard management yet. We present a technique for posterolateral instability of the knee using tibialis posterior tendon allograft, which reconstructed lateral collateral ligament and popliteal tendon.
