Abstract

Objectives: In this study, we introduce the SanatSwing cementless total knee prosthesis coated with a combination of titanium plasma spray and hydroxyapatite porous coating and compared its early results to the SanatSwing cemented knee prosthesis. Patients and methods: We compared 278 patients, who underwent total knee replacement between September 2012 and February 2017. A total of 142 patients (Group A; 78 male, 64 female, mean age 69±14) were implanted a cemented SanatSwing and 136 patients (Group B; 83 male, 53 female, mean age 59±10), a cementless SanatSwing knee prosthesis was implanted. Implant position and periprosthetic bone conditions were investigated over time on radiographs after a mean follow-up period of two years. Range of motion, pain level, distance of painless walk, and the ability to climb stairs were evaluated. Results: Significant improvement was observed in both the cemented and uncemented groups when the preoperative scores were compared to the scores of their final visit, but we did not find any difference in measured scores between the cemented and uncemented group. Complication rates were low and almost similar in both groups without any significant difference. Conclusion: We used the combination of titanium plasma spray and the hydroxyapatite porous coating technique in cementless prostheses. Our results showed us that the novel SanatSwing cementless total knee prosthesis could be a great alternative to cemented total knee arthroplasty.
