Intraoperative Graft Isometry in Anatomic Single-Bundle Anterior Cruciate Ligament Reconstruction.

Purpose: Little is known about the isometry of anatomic single-bundle anterior cruciate ligament (ACL) tunnel positions although it is closely related to graft tension throughout the range of motion. The purpose of this study was to evaluate intraoperative graft isometry in anatomic single-bundle ACL reconstruction .

Materials And Methods: Graft length changes were assessed before bio-screw fixation in the tibial tunnel by pulling the graft with tensions of 20 lbs and 30 lbs in full extension at flexion angles of 30°, 60°, 90°, and 120°.

A Systematic Review of Interspinous Dynamic Stabilization.

Background: A systematic literature review of interspinous dynamic stabilization, including DIAM, Wallis, Coflex, and X-STOP, was conducted to assess its safety and efficacy.

Methods: The search was done in Korean and English, by using eight domestic databases which included KoreaMed and international databases, such as Ovid Medline, Embase, and the Cochrane Library. A total of 306 articles were identified, but the animal studies, preclinical studies, and studies that reported the same results were excluded.

Cementless and cemented total knee arthroplasty in patients younger than fifty five years. Which is better?

Purpose: The purpose of this prospective, randomised study was to evaluate long-term clinical results, radiographic findings, complications and revision and survivorship rates in patients <55 years at a minimum of 16 years after undergoing bilateral, sequential, simultaneous, cemented and cementless total knee arthroplasties (TKAs) in the same patients.

Methods: Bilateral, sequential, simultaneous TKAs were performed in 80 patients (160 knees). There were 63 women and 17 men with a mean age of 54.

Morphologic Changes of the Posterior Cruciate Ligament on Magnetic Resonance Imaging before and after Reconstruction of Chronic Anterior Cruciate Ligament Ruptures.

Purpose: The purpose of this study was to compare the morphologic change of the posterior cruciate ligament (PCL) on magnetic resonance imaging (MRI) in chronic anterior cruciate ligament (ACL) tear before and after reconstruction.

Materials And Methods: On the MRI image after ACL reconstruction, a base line (BL) was drawn between the femoral and tibial insertion sites of the PCL. Point A was established as the vertically farthest point from BL.

Idiopathic extension contracture of the little metacarpophalangeal joint.

We describe 4 patients with an extension contracture of the little metacarpophalangeal joint without definite cause. We encountered this entity only in adolescent girls. When treated conservatively, we observed no improvements in motion.
