Objective: The aim of this study was to investigate the early clinical outcome after total knee arthroplasty (TKA) using the FINE TKA system.
Methods: Forty people who underwent 42 TKAs using the FINE TKA system participated in this study. Functional evaluations were performed at admission, discharge, and 23 months and 6 months after surgery. Evaluations consisted of the range of motion of the knee and radiographic measurements of the angle of implantation (Knee Society score).
Results: Japanese Orthopedic Association (JOA) scores after more than 6 months were significantly improved as compared to the scores at initial evaluation (p＜0.001). The range of knee flexion was 130.7° at admission, 130.0° at discharge, 120.7° at 2-3 months after surgery, and 122.3° at the last evaluation. The angle of implantation (α, β, γ, δ angle) was favorable.
Conclusion: Our study shows that the FINE TKA system has satisfactory clinical performance that is comparable to that achieved using other prostheses designed for Japanese patients to achieve good early clinical outcomes.
