PURPOSE: The purpose of this multicentre observational study is to evaluate implant survival and patient-reported outcome measures (PROMs) at 3-5 years following individualised total knee arthroplasty (TKA). METHODS: A consecutive series of 426 patients (434 knees) underwent CT-based, posterior-stabilised, cemented, individualised TKA between December 2018 and August 2020. After excluding 73 patients without informed consent, 353 patients (361 knees) were included for survival analysis. A further 74 were excluded (revised = 2, deceased = 11, inadequate follow-up = 61), resulting in a final cohort of 279 patients (287 knees) for PROMs assessment. Implant survival was evaluated using the Kaplan-Meier (KM) method, with revision of any component for any reason as the endpoint at 2- and 3-year follow-ups. Patients completed pre and postoperative questionnaires of the Oxford knee score (OKS) and the forgotten joint score (FJS), and also rated their level of satisfaction on a 4-level Likert scale. The proportion of patients who achieved a patient acceptable symptom state (PASS) was estimated according to the threshold of 30 for OKS and 38 for FJS. RESULTS: Considering revision for any reason as endpoint, the survival according to the KM method was 99.4% (95% confidence interval [CI] 98.6%-100.0%) at both 2- and 3-year follow-up. The OKS improved from 22.2 ± 8.4 to 40.6 ± 7.6, and 244 knees (85%) achieved the PASS. The FJS improved from 16.7 ± 14.6 to 68.5 ± 27.7, and 233 (81%) achieved the PASS. Out of the 254 knees with their rated level of satisfaction, 250 (98.4%) were either satisfied or very satisfied. CONCLUSION: At 3 to 5 years' follow-up, individualised TKA demonstrated excellent implant survival (99.4%), as well as high patient satisfaction, both considering and disregarding non-respondents (87.1% and 98.4% respectively). The results are promising and warrant continued follow-up to evaluate long-term results. LEVEL OF EVIDENCE: Level IV.
