Purpose The purpose of this study was to evaluate the 5‐year follow‐up results of the first 200 total knee arthroplasties (TKA) performed by one high‐volume surgeon, using patient‐specific information (PSI). To date, there has been no other research into the mid‐term follow‐up of TKA performed using PSI. Materials and methods A total of 184 consecutive patients (200 TKA) were evaluated. Outcome measures included implant survival rate, adverse events, and the following patient‐reported outcome measures (PROMs); Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Oxford Knee Score (OKS), Pain Visual Analogue Score (VAS) and EuroQol‐5D Score (EQ‐5D). Results Revision surgery was performed for late secondary prosthetic joint infection ( n = 1, total revision), aseptic loosening ( n = 1, tibial component revision), instability ( n = 1, isolated polyethylene insert exchange), and polyethylene insert breakage ( n = 1, isolated polyethylene insert exchange). Other adverse events were as follows: debridement, antibiotics and implant retention for early prosthetic joint infection ( n = 1), surgical debridement for haemarthrosis ( n = 1), superficial wound infection ( n = 2), thromboembolic events ( n = 2), compartment syndrome ( n = 1), and nerve injury ( n = 2). All median outcome scores for patient reported outcome measures at 5 years improved significantly compared with the preoperative values ( p ≤ 0.05). Median outcome scores were not significantly different between 1‐ and 5‐year moments of follow‐up, except for a significant decrease of EQ‐VAS ( p ≤ 0.05) between these two follow‐up moments. Conclusion PROMs are consistent for 5‐year follow‐up of TKA using PSI. After 5 years of follow‐up, revision surgery for any reason occurred in four patients (2%). Level of Evidence III.
