Purpose: This study compared the results of PFC Sigma RP-Fⓡ total knee arthroplasty with those of conventional total knee arthroplasty using PFC Sigma PSⓡ in order to assess the clinical results including the maximal flexion angle after a follow up of at least 2 years.
Materials and Methods: Forty one cases of total knee arthroplasty were performed with PFC Sigma RP-Fⓡ, and the clinical results were analyzed after a follow up of at least 2 years. The patients were compared with a control group consisting of 41 cases, who underwent total knee arthroplasty with PFC Sigma PSⓡ using the following parameters: gender, preoperative diagnosis, and preoperative range of motion, and postoperative range of motion.
Results: The mean follow up period was 26.7 months. The KSS score improved from 53.2 preoperatively to 95.6 postoperatively. The KSFS score also improved from 49.7 preoperatively to 96.1 postoperatively. The range of motion increased from 124.3o to 128.2o. The subjective pain score using visual analogue scale improved from 7.6 preoperatively to 1.4 postoperatively. The group with the PFC Sigma RP-Fⓡ showed similar clinical results to the PFC Sigma PSⓡ except for the range of motion.
Conclusion: Total knee arthroplasty with PFC Sigma RP-Fⓡ showed similar clinical results to other models, as well as excellent and predictable results of range of motion at the short-term follow up. A long term follow up study will be needed to demonstrate its effects on increasing the longevity.
