Abstract

We compared clinical [including maximal flexion and range of motion (ROM)] and radiographical outcomes of high-flex versus conventional implants for total knee arthroplasty (TKA) after 1 year. We also analyzed the factors affecting postoperative ROM in high-flex implants. The high-flex group (n = 90) had an average maximal flexion of 129.8° (standard deviation (SD), 5.2°) significantly higher than the 124.3° (SD, 9.2°) of the conventional group (n = 90), especially for patients with less than 90° of knee flexion (P < 0.05). There was no significant difference in hospital for special surgery (HSS) score between the two groups. No knee developed osteolysis, aseptic loosening, or other complications. We found that, for high-flex implants, preoperative ROM had a significant effect on postoperative ROM.
