Abstract
Purpose
The Persona® system is a newly launched implant designed for total knee arthroplasty (TKA) with technical innovations intended for a better functional outcome and higher flexion range. The aim of this study is to evaluate midterm outcomes and survivorship of a cohort of patients with a minimum of 5-year follow-up and to confirm previous results described in the literature.
Methods
A cohort of 91 knees (85 patients) that underwent a patella-preserving TKA with the Persona® implant and who were followed for a mean of 5.9 years’ period was included in the study. Functional values were measured: Oxford Knee Score (OKS), Knee Society Knee score (KSKS) and Knee Society Function score (KSFS). Range of movement (ROM), lower limb axis correction, mobilization and complications were also registered at the last follow-up and underwent statistical analysis.
Results
We found a low rate of complications or radiological changes with an implant-related revision rate of 2.19%. Mean results for PROMS were 44.21 ± 4 in OKS, 90.94 ± 2.4 in KSS and 97.88 ± 9.6 in KSFS. Mean postoperative ROM was 120.8º ± 12.37º. There was no change in implant positions at the final follow-up. We found radiolucent lines in 3 knees (3.29%).
Conclusion
At a mean follow-up of 5.9 years, the implant-related cumulative percentage revision rate was 3.3% (2 of 91) at a mean follow-up of 5.9 years, with good clinical and functional results.
