Our results indicate that distal chevron osteotomy with a distal soft tissue procedure provides an effective and reliable means of correcting moderate to severe hallux valgus deformity, and that it does so with high levels of patient satisfaction and low incidence of complications.

Two postoperative treatments differing by weightbearing status after arthroscopic microfracture for small to midsized osteochondral lesions of the talus showed good clinical results and similar outcomes in terms of the AOFAS score, VAS score, and AAS. The study shows that early weightbearing postoperative regimens can be recommended for patients treated by microfracture for small to midsized osteochondral lesions of the talus.

For knees managed with a cruciate-retaining total knee arthroplasty, those that had the high-flexion design and those that had the standard design were found to have a similar range of motion under both non-weight-bearing and weight-bearing conditions. Moreover, no significant difference was found in terms of the other functional outcomes examined.

Both the screw and suture fixation techniques for the anterior cruciate ligament tibial avulsion fracture produced relatively good results in terms of functional outcomes and stability without any significant differences. However, some patients in both groups showed residual laxity or flexion contractures.

This international consensus derived from leaders in the field will assist clinicians with debridement, curettage and bone marrow stimulation as a treatment strategy for osteochondral lesions of the talus.

This study was undertaken to compare the clinical and radiological outcomes achieved using total knee arthroplasty (TKA) with and without a navigation system. This study included 43 TKAs performed with a navigation system and 42 TKAs without a navigation system with a minimum two-year follow-up. We compared clinical outcomes including range of motion, Hospital for Special Surgery (HSS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores at the final follow-up. For radiological comparisons, we evaluated radiological alignment on standing radiographs of knees. HSS and WOMAC scores showed significant improvements at final follow-ups in both groups, but showed no significant inter-group differences (p>0.05). Similarly, no significant differences were observed in range of motion (p =0.962). TKAs performed with navigation showed significantly better outcomes in terms of mechanical angle and prosthetic alignment outliers than TKAs performed without navigation. However, we could not find any differences in functional outcomes between TKAs performed with or without a navigation system. Résumé: Cette étude a pour but de comparer le devenir clinique et radiologique de prothèses totales du genou avec ou sans utilisation d'un système de navigation. 43 prothèses ont été réalisées avec navigation et 42 sans navigation. Le suivi minimum a été de deux ans. Nous avons comparé les résultats cliniques incluant la mobilité, le score HSS, le score WOMAC. Sur le plan radiologique nous avons évalué les axes en position debout. Les scores HSS et WOMAC montraient une très nette amélioration au suivi final dans les deux groupes mais, sans différence significative entreeux (p>0,5). De la même façon nous n'avons pas trouvé de différence significative au niveau de la mobilité (p=0,962). Par contre, la réalisation d'une prothèse totale du genou avec un système de navigation permet d'améliorer de façon significative l'axe mécanique angulaire de la prothèse en évitant un certain nombre d'anomalies axiales extrêmes que l'on peut rencontrer lorsque l'on réalise ces prothèses sans navigation. Cependant, il n'est pas possible de trouver une différence sur le plan fonctionnel entre les prothèses totales du genou réalisées avec ou sans système de navigation.
