Impacted bone allograft personalised by a novel 3D printed customization kit produces high surgical accuracy in medial opening wedge high tibial osteotomy: a pilot study.

Purpose: Contemporary medial opening wedge high tibial osteotomy (MOWHTO) still seems to struggle with inconsistent accuracy outcomes. Our objective was to assess surgical accuracy and short-term clinical outcomes when using 3D planning and a patient-specific instrumentation (PSI) kit to prepare customized bone allografts.

Methods: Thirty subjects (age 48y ± 13) were included in a double-center prospective case series.

Changes in knee joint line orientation after high tibial osteotomy are the result of adaptation of the lower limb to the new alignment.

Background: Changes in knee joint line orientation (KJLO) resulting in excessive joint line obliquity are a well-known consequence of high tibial osteotomy (HTO) procedures and could lead to degenerative changes. The precise effect of the correction on final KJLO changes is poorly understood. The goal of this study was to identify radiographical parameters that could help to explain the size of KJLO changes after HTO surgery.

Magnetic Resonance Imaging Evaluation of the Anterolateral Ligament and the Iliotibial Band in Acute Anterior Cruciate Ligament Injuries Associated With Segond Fractures.

Purpose: To evaluate the magnetic resonance imaging (MRI) characteristics of Segond fractures, including the structures attached to the avulsed fragment, the integrity of anterolateral ligament (ALL) and iliotibial band (ITB), and fragment size and location.

Methods: This was a retrospective, cross-sectional study with MRI scans from 2016 to 2019 with the term "Segond" in the reports, signs of acute trauma, and a bony anterolateral tibial avulsion (Segond) fracture. Two experienced observers accessed images to evaluate fragment dimensions (anteroposterior, mediolateral, and craniocaudal) and distances from anatomic landmarks (Gerdy's tubercle, articular surface, and posterolateral tibial corner).

Structural allograft impaction enables fast rehabilitation in opening-wedge high tibial osteotomy: a consecutive case series with one year follow-up.

Purpose: Painful and slow recovery are the presumed disadvantages after opening-wedge high tibial osteotomy (HTO) and play a role in favouring arthroplasty as treatment for moderate isolated medial knee arthritis. The primary study objective was to investigate the effect of press-fit structural impacted bone allograft with locking plate fixation on early ambulation, postoperative pain levels, and resumption of daily-life activities in opening-wedge HTO.

Methods: A prospective consecutive opening-wedge HTO case series was conducted, including 103 patients with final follow-up at 1 year.

High prevalence of anterolateral ligament abnormalities in magnetic resonance images of anterior cruciate ligament-injured knees.

The purpose of this study was to identify the newly described anterolateral ligament of the human knee on magnetic resonance imaging and to describe its eventual radiological abnormalities in anterior cruciate ligament-injured subjects. A retrospective cohort study on a series of consecutive subjects undergoing anterior cruciate ligament reconstructive surgery was performed. The MR images of 206 included knees were studied and the status of the anterolateral ligament status was judged to be either "non-visualized", "normal" or "abnormal".
