摘要：

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 degrees ( standard deviation (SD), 5.2 degrees) significantly higher than the 124.3 degrees ( SD, 9.2 degrees) of the conventional group ( n = 90), especially for patients with less than 90 degrees 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.
