Synovial Fluid Biomarkers for the Diagnosis of Periprosthetic Joint Infection-A Systematic Review and Meta-Analysis of Their Diagnostic Accuracy According to Different Definitions.

Background: Different synovial fluid biomarkers have emerged to improve periprosthetic joint infection (PJI) diagnosis. The goals of this paper were (i) to assess their diagnostic accuracy and (ii) to evaluate their performance according to different PJI definitions.

Methods: A systematic review and meta-analysis was performed using studies that reported diagnostic accuracy of synovial fluid biomarkers using validated PJI definitions published from 2010 to March 2022.

Surgical Treatment for Congenital Dislocation of the Patella in a Young Adult: A Case Report.

Case: We present an 18-year-old man with poor alignment of the lower limbs, marked by congenital dislocation of the left patella, with gait impairment, and an associated 20° flexion contracture. Surgical treatment was performed with a single complex procedure with the release of the lateral retinaculum, capsule, and iliotibial tract, followed by a subtraction trochleoplasty, tibial tubercle transfer, elongation of the quadriceps tendon, and anatomical reconstruction of the medial patellofemoral ligament. At the 5-year follow-up, the patient had a significant improvement in gait pattern, with the patella centered on the new trochlear groove without any signs of patellar instability.

Odontoid Fractures: A Critical Review of Current Management and Future Directions.

Odontoid fractures represent one of the most common and controversial injury types affecting the cervical spine, being associated with a high incidence of nonunion, morbidity, and mortality. These complications are especially common and important in elderly patients, for which ideal treatment options are still under debate. Stable fractures in young patients maybe treated conservatively, with immobilization.
