Background: Genu recurvatum is a rare knee deformity. Total knee arthroplasty (TKA) in severe preoperative recurvatum requires surgical adjustments. Few studies have assessed the clinical and radiological results of TKA in recurvatum. The aim was to compare the clinical and radiological outcomes, complications, and revision rates after posterior-stabilized TKA in severe recurvatum with those without recurvatum.
Methods: Between 1987 and 2015, 32 primary posterior-stabilized TKA were performed with a preoperative genu recurvatum greater than 10° and minimum follow-up of 60 months. In severe genu recurvatum, the extension gap needs to be decreased compared with flexion gap. To achieve this, the distal femoral cut is distalized, whereas the posterior femoral and tibial cuts are performed as usual. They were compared with 64 matched posterior-stabilized TKAs without recurvatum. The demographic data were similar between groups. The clinical and radiological outcomes, complications, and revision rates were assessed at the last follow-up.
Results: At a mean follow-up of 7.4 years ± 1.9, there was no significant difference in International Knee Score functional score (77.5 vs. 73.4; P = .50) and knee score (86.6 vs. 89.5; P = .37) between the recurvatum group and the control group, respectively. 6 patients had a postoperative recurvatum equal or superior to 10° in the recurvatum group (18.8%). There was no difference between both groups in radiological outcomes, complication, or revision rates. No instability was found in the recurvatum group.
Conclusion: Posterior-stabilized TKA with controlled distalization of the femoral component in the setting of severe preoperative genu recurvatum achieves good clinical and radiological outcomes at a minimum follow-up of 5 years and similar to TKA without preoperative recurvatum.
Level Of Evidence: III.

Introduction And Importance: The estimated incidence of congenital dislocation of the knee, also referred to as genu recurvatum, is approximately 1 in 100,000 live births. The purpose of this report is to present a rare case of unilateral congenital knee dislocation, highlighting the clinical presentation and management.
Case Presentation: A 9-day-old female infant was born to a 30-year-old primigravida mother following an uncomplicated term pregnancy of 39 weeks and 4 days.

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.

Aim: To identify the short-term effects of selective dorsal rhizotomy (SDR) on gait and clinical impairments in children with bilateral spastic cerebral palsy (CP) and subgroups based on baseline gait patterns.
Method: Eighty-nine children with bilateral spastic CP (55 males, mean age [SD] before SDR: 9 years 5 months [2 years 3 months]; Gross Motor Function Classification System level I: 18; II: 54; III: 17) received three-dimensional gait analyses at two time points (baseline and 1 year after SDR); their baseline gait patterns were classified. The analysis included the comparisons of (1) sagittal plane kinematic waveforms, the Gait Profile Score, and non-dimensional spatiotemporal parameters between the two time points, (2) the kinematic waveforms of both time points to those of typically developing children, and (3) composite impairment scores of spasticity, weakness, and selectivity between the two time points.

Background: In the realm of research, the single case study has been recognized as a valuable tool for sharing insights, demonstrating new concepts, discovering novel phenomena, consolidating hypotheses, and sparking original ideas. In this physician-guided narrative, phenomena previously unreported in the clinical context are explored. These case studies aim to offer insights that may inform an existing theoretical model that encapsulates a distinct therapeutic intervention.
