Objective: To analyze the clinical and radiologic results, the survival and complications obtained in 70 year or older patients who underwent cementless total knee arthroplasty (TKA)., Material and Method: An observational study of patients operated between January 2014 and December 2016 was carried out according to the Natural Knee model (Zimmer®, USA). The main variables were the Oxford Knee Score, the visual analog scale, the presence of radiolucencies, complications, survival and reasons for revision., Results: Of 104 TKA, 86 were available for revision. The median age was 76 years. The mean follow-up was 5.4 years (range 3.7-6.9). The Oxford Knee Score punctuation showed a median of 17 presurgical (range 0-40) and 37 post surgical (range 5-48), P<.001. The 87.2% of the patients obtained a clinically significant improvement. The median visual analog scale punctuation was 8 for presurgical (range 4-10) and 2 for post surgical (range 1-9), P<.001. The 88.3% of the patients obtained a clinically significant decrease. Three months after the surgery, the 55.81% of the TKAs presented radiolucencies around the tibial plateau. At the end of the follow-up, radiolucencies were present in 30.23% of the TKAs. Survival from all causes was 91.86% at 77.2 months and 96.5% due to aseptic loosening., Conclusion: Cementless knee prostheses are a valid option in patients aged 70 or older, presenting good clinical, radiological and survival results., (Copyright © 2021 SECOT.

Introduction: One of the most frequent complications after a total hip arthroplasty (THA) is bleeding, intravenous tranexamic acid (TXA) is used to reduce it. We considered it necessary to carry out a study to clarify which administration route is superior., Material and Method: Prospective, controlled and randomized study in 2 arms carried out between February 2017 and February 2018. 15mg/kg of intravenous TXA were administered in group-A and 2gr of intra-articular TXA in group-B. The values of haemoglobin and haematocrit were evaluated at 24h-72h, blood loss volume, drained blood volume, transfusions and complications., Results: 78 patients were included, 31 with intravenous treatment and 47 with intra-articular. The decrease of haemoglobin in the intravenous group was 3.15±1.64g/dl in 24h and 3.75±1.56g/dl in 72h, the haematocrit decreased by 10.4±4.17% in 24h and 11.85±4.15% in 72h. In the intra-articular group there was a haemoglobin fall of 3.03±1.30g/dl in 24h and 3.22±1.2g/dl in 72h and the haematocrit fell by 10.66±3.6% and 12,11±3.29% in 24 and 72h (P>.05). The mean drainage in 24h was 195.80ml in group-A versus 253.93ml in group-B (P>.05) and in 48h it was 225.33ml in group-A and 328.19ml in group-B (P=.009). The intravenous group lost an average of 1,505ml of blood compared to the 11,280ml of the intra-articular group. In 5.1% of the cases, transfusions were necessary. We had no secondary complications., Conclusions: The different routes of administration of TXA in THA have a similar effect in the reduction of postoperative bleeding. There was no evidence of an increase in complications., (Publicado por Elsevier España, S.L.U.)
