Abstract EN
Background.
Indication for rotating hinge (RH) total knee arthroplasty (TKA) includes primary and revision cases, with contradictory results.
The aim of this study was to report prospective early results of a new modular rotating hinge TKA (EnduRo).
For this implant several new design features and a new bearing material (carbon-fiber reinforced poly-ether-ether-ketone) have been developed.
Furthermore, we tried to establish a new classification of failure modes for revision TKA.
Methods.
152 EnduRo rotating-hinge prostheses were implanted in two centers.
In 90 patients a primary implantation has been performed and 62 patients were revision cases.
Knee Society Score (KSS), Western Ontario and McMaster Osteoarthritis Index (WOMAC), Oxford Knee Score (OKS), and Range of motion (ROM) were assessed before surgery, 3 months postoperatively, 12 months postoperatively, and annually thereafter.
We defined 3 types of complications: Type 1, infection; type 2, periprosthetic complications; type 3, implant failures.
Results.
KSS, WOMAC, OKS, and ROM revealed significant improvements between the preoperative and the follow-up investigations.
There were 14 complications (9.2%) leading to revision surgery, predominantly type 2.
Conclusion.
Our study shows excellent clinical results of the EnduRo TKA.
Furthermore, no premature material failure or unusual biological response to the new bearing material could be detected.
