This letter evaluates the methodological shortcomings in the FEA research conducted by Ma et al. (2025) that contrasts hook plates with tension-band wiring for patellar fractures. Unresolved concerns consist of: uniform bone material characteristics simplifying biomechanics; static loads neglecting dynamic physiological forces; idealized fracture spaces missing clinical variation; and unverified interfaces exaggerating stability. These gaps may exaggerate the effectiveness of the implant. We suggest personalized modeling, simulations of dynamic loading, and studies on mesh convergence to enhance clinical significance. Tackling these issues would enhance forthcoming evaluations of orthopedic devices based on FEA.
