| 520 | 3 | |a Purpose: The main purpose of the present study was to determine long-term implant fixation of 15 unicompartmental knee arthroplasty (UKAs) with an all-poly tibial component using Roentgen stereophotogrammetric analysis (RSA) at a mean 10-year follow-up. The secondary purpose was to investigate whether the progressive loss of implant's fixation correlates with a reduction in Knee society score (KSS). Methods: Fifteen non-consecutive patients with primary knee osteoarthritis received a UKA with an all-poly tibial component were assessed using KSS scores pre-operatively and post-operatively and RSA on day 2 after surgery, then at 3, 6, and 12months and yearly thereafter. The mean last follow-up was 10years. Results: An increase in maximum total point motion (MTPM) values from 6months to 1year post-operatively was found respect to post-operative reference. Implants' displacement values were always <2mm during the first 6months, and then, two different trends were noticed in revised and non-revised implants. MTPM increase between 1 and 2years of follow-up in non-revised UKAs was always <0.2mm, whereas it was >0.2mm in revised UKAs. A linear and negative correlation with statistical significance was found between MTPM and both clinical and functional KSS scores (p<0.001). Conclusion: Also in a long-term follow-up evaluation, RSA is an effective tool to predict functional results after an all-poly UKA providing also a relevant predictive value at 1year follow-up, and this can be very useful for both patients and surgeons. Level of evidence: Diagnostic studies, Level III. | |
