We reported the mid-term results of 15 knees in 10 patients with ostheoarthritis treated by NexGen® LPS-Flex total knee arthroplasty (TKA). Patients received clinical and radiological evaluation. Three males and 7 females with a mean age of 76.2 years were followed up for a period of 48 to 65 months (mean follow up 54.4 months). Preoperative mean flexion angle improved after the procedure from 130.1 to 138.0. In addition, mean preoperative range of motion increased from 130.7 to 137.0, after surgery. The mean Japanese Orthopedic Association knee rating score improved from 50.7 to 91.7 points. Clinical complications were not observed. There was no radiographic evidence of loosening or sinking. Correlation between the body mass index/postoperative flexion angle, and preoperative/postoperative flexion angle were statistically significant.
The use of LPS-Flex in our mid-term evaluation is associated with an improvement of flexion accompanied with good clinical outcome.
