Analysis of complications following total knee replacement with a cemented condylar endoprosthesis

Background. Advanced knee arthritis is indicated for total alloplastic and it is considered to be the method of choice. It allows on abolishing of intensive pain and correcting of efficiency of limb. Material and methods. Postoperative complications were analysed in 109 operated knees in 93 patients. Condylar knee endoprotheses of types AGC I, AGC II, and Scorpio were implanted between 1996 and 2004. 92 implants were crucial retaining and 17 posterior stabilized. The age of the patients ranged from 39 to 84 years (mean 67.1). The follow-up period was from 10 months to 8 years and 3 months (mean 5 years and 2 months). 84 knees were operated in women and 25 in men. The HSS scale was used for evaluation of results. Results and Conclusions. From among the most important complications affecting the ultimate outcome, there were 3 early infections (2.7%), one late infectious complication (0.9%), one sterile destabilization of both elements (0.9%), and 2 cases (1.8%) of increasing, significant restriction of the range of movement. In 91 cases the outcome was very good or good, in 11 cases satisfactory, and in 7 cases poor.
