Biomechanical assessment of ligament maturation after arthroscopic ligament reconstruction of the anterior talofibular ligament.

Background: Many techniques have been described for lateral ankle ligament reconstruction. Although the biomechanical properties of gracilis tendons are different from those of ligaments, the use of a gracilis tendon autograft is a popular option for anatomical reconstruction. Graft maturation and the biomechanical processes over time remain unclear.

Total knee arthroplasty in patient with poliomyelitis sequelae: maintaining a recurvatum is associated with better mid-term functional results.

Purpose: Total knee arthroplasty (TKA) in patients with sequelae of poliomyelitis is a surgical challenge due to muscle weakness, bone deformities or post-polio syndrome (PPS). Few data exist to determine the factors contributing to poor functional results. This study aimed: (1) to describe a cohort of patients with poliomyelitis sequelae who underwent TKA; (2) to examine risk factors for poor functional outcome.

MRI evaluation of ATFL and CFL ligamentization after anatomical surgical reconstruction with a hamstring graft.

Background: Chronic ankle instability is frequent complication following ankle sprains. Anatomical reconstruction of the anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL) with a gracilis autograft is a validated reconstruction technique. The signal-to-noise quotient ankle (SNQA) score evaluates graft maturation with MRI and has been shown to be reproducible and reliable.

Anterior-approach total hip arthroplasty in patients with poliomyelitis: Long-term outcomes.

Objective: In patients with residual poliomyelitis-related impairments, total hip arthroplasty (THA) is challenging due to the high frequency of risk factors such as hip dysplasia, dislocation, muscle weakness, and fracture. The objective of this study was to assess the long-term functional and radiographic outcomes of anterior-approach THA with a ceramic-ceramic, dual-mobility, or constrained implant in patients with poliomyelitis sequelae.

Hypothesis: THA via the anterior approach with a ceramic-ceramic, dual-mobility, or constrained implant is a reliable technique that is not associated with excess risks of instability or aseptic loosening.
