- Abstract:
- INTRODUCTION The scientific community has faced much debate on the topic of gender and different outcomes between female and male patients after implantation of low-contact-stress (LCS) total knee arthroplasty (TKA). OBJECTIVES The objective of this study was to investigate outcome differences between female and male patients after implantation of low-contact-stress (LCS) mobile-bearing total knee prostheses (TKA) at a minimum follow-up of ten years with respect to clinical and radiological parameters. METHODS All patients undergone implantation of LCS TKA in our department with a minimum follow-up of 10 years were invited retrospectively, using our hospital database. Data was extracted with respect to range of motion (ROM), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, the Knee Society Score (KSS), the visual analogue scale (VAS), and radiological signs of loosening on conventional X-rays. We used SPSS 20 for statistical analysis and a p-value <0.05 was set for significance. RESULTS The database search revealed 467 Patients with 546 TKAs in total. After exclusion of the deceased, 236 patients remained for analysis. Eighty-four prostheses out of 66 patients could be clinically examined. At follow-up, we observed no significant differences between female and male patients in terms of the above-mentioned parameters. Further 42 patients were additionally interviewed by telephone interview. CONCLUSION Clinical or radiological outcomes do not significantly differ between female and male patients after implantation of LCS total knee prostheses at ten years of minimum follow-up. We therefore found no factors in favor of gender-specific total knee prostheses.
