Ten-Year Results of the Press Fit Condylar Sigma Cobalt –Chrome Total Knee Replacement

J Knee Surg DOI: 10.1055/s-0038-1641138Total knee arthroplasty (TKA) is reliant on safe and effective implants. The Press Fit Condylar Sigma Cobalt–Chrome (PFCSCC) was introduced in 2006, but no reports have examined long-term failure rates and patient-reported outcome measures (PROMs). The primary aim of this study was to assess survival outcomes of the PFCSCC at 10 years after implantation. Prospective data collection was performed on all patients undergoing primary TKA in one orthopaedic department using this prosthesis exclusively from February 1, 2006, to January 31, 2007. Follow-up was at 10 years. Survival analysis was performed using two primary outcome measures: (1) all-cause joint revision and (2) aseptic revision. Secondary outcomes measures included the American Knee Society Score (AKSS) and Oxford Knee Score (OKS). In total, 249 knees of 233 patients underwent primary TKA. Mean patient age was 66.7 years (range 34–80), and mean body mass index (BMI) was 30 kg/m2 (20.7–40.1). Reviewing all causes of revisions, 14 joints (5.6%) of 14 patients required reoperation. Of these, nine were for deep infection, including six in the first year. Four (1.6%) underwent aseptic revision. Mean AKSS changed from 47.6 to 90.4 (n = 140; p

CONCLUSIONS: Using data representing over 99% of U.S. population, we found that incidence rates of distant-stage prostate cancer significantly increased during 2010-2014 among men in certain ages, in white, and with non-Hispanic ethnicity. PMID: 29678312 [PubMed - in process]

CONCLUSION: CRC incidence increased with neighborhood disadvantage and racial disparities diminished with mounting disadvantage. Our results suggest additional dimensions to racial disparities in CRC outside of neighborhood disadvantage that warrants further research. PMID: 29678311 [PubMed - in process]

Conclusion: Our results suggest that the concentration of serum calcium is higher in patients with more severe artery stenosis lesions and that the phosphatidylinositol signaling system is a key biological pathway involved in this process.Cell Physiol Biochem 2018;46:1189 –1197

Conclusion: Rat hepatocytes with their intermediate rate of oxygen consumption also possess an intermediate CO2 permeability. From pairs of data for five types of cells/organelles, we find an excellent positive linear correlation between PCO2 and metabolic rate, suggesting an adaptation of PCO2 to the rate of O2 consumption.Cell Physiol Biochem 2018;46:1198 –1208
