RESUMO
Total knee arthroplasty (TKA) is a gold standard surgical procedure to improve pain and restore function in patients affected by moderate-to-severe severe gonarthrosis refractory to conservative treatments. Indeed, millions of these procedures are conducted yearly worldwide, with their number expected to increase in an ageing and more demanding population. Despite the progress that has been made in optimizing surgical techniques, prosthetic designs, and durability, up to 20% of patients are dissatisfied by the procedure or still report knee pain. From this perspective, the introduction of robotic TKA (R-TKA) in the late 1990s represented a valuable instrument in performing more accurate bone cuts and improving clinical outcomes. On the other hand, prolonged operative time, increased complications, and high costs of the devices slow down the diffusion of R-TKA. The advent of newer technological devices, including those using navigation systems, has made robotic surgery in the operatory room more common since the last decade. At present, many different robots are available, representing promising solutions to avoid persistent knee pain after TKA. We hereby describe their functionality, analyze potential benefits, and hint at future perspectives in this promising field.
RESUMO
The aim of this study was to investigate clinical and instrumental outcomes of the autologous matrix-induced chondrogenesis (AMIC) technique for the treatment of isolated traumatic condyle and femoropatellar cartilage lesions. A total of 25 patients (12 males, 13 females, mean age 47.3 years) treated between 2018 and 2021 were retrospectively reviewed and subdivided into two groups based on age (Group A, age < 45 years; Group B, age > 45 years). A clinical evaluation was performed using the International Knee Documentation Committee (IKDC), Lysholm score and Visual Analogue Score (VAS). Cartilage regeneration was evaluated via magnetic resonance (1.5 Tesla) and classified according to a Magnetic resonance Observation of CArtilage Repair Tissue (MOCART) scoring system. At a minimum follow-up of 2 years, Group A patients obtained greater instrumental results in comparison to group B: in fact, the MOCART score was statistically significantly correlated with IKDC (r = 0.223) (p < 0.001) exclusively in group A. Nevertheless, a significant improvement in clinical functionality was shown in Group B (p < 0.001), demonstrating that this technique is safe, reproducible and capable of offering satisfactory clinical results regardless of age.
RESUMO
Background: Intraoperative findings during laparoscopic cholecystectomy (LC) are highly unpredictable and operative difficulty varies from straightforward to very challenging procedures. Several studies described predictors of technical difficulty and graded intraoperative findings of LC; however, none specifically reported on the effect of such factors on clinical outcomes. This study aims to evaluate if preoperative characteristics of patients undergoing LC predict how likely they are to fail to be day case (DC). Methods: Data of patients who underwent LC from 2015 to 2017 were retrospectively analyzed. Subjects were divided into four groups, according to Nassar's classification of intraoperative difficulty. Differences in frequencies were evaluated with the the chi square and post hoc chi square tests or Fisher's exact test; logistic regression analysis was used to identify independent variables that were predictors of intraoperative complexity, postoperative morbidity, and length of stay. Results: A total of 1043 patient were included with male to female ratio of 1:2.5. Older age, male gender, and comorbidities were associated with higher Nassar score (P < .0001); Nassar 3 and 4 were predictors of postoperative morbidity (P < .05). The DC rate was 74.2% (Nassar 1), 75.8% (Nassar 2), 61.1% (Nassar 3), and 26.2% (Nassar 4), respectively. Age ≥60 years (P < .05), body mass index ≥35 (P < .05), and Nassar 3 and 4 (P < .05) were predictors of increased conversion from DC to inpatient (IP) stay. Conclusion: LC can be safely performed on a DC basis even when surgery is technically challenging. The need of IP stay can be predicted in comorbid old adult men with anticipated higher Nassar's score.
