ABSTRACT
OBJECTIVE:
To analyse the clinical and radiologic results, the survival and complications obtained in 70 year or older patients who underwent cementless total knee arthroplasty (TKA). MATERIAL ANDMETHOD:
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 analogue 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 analogue 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.
