The present disclosure discloses a zonal trabecular uni-compartmental femoral condylar component containing zirconium-niobium alloy on oxidation layer and preparation method, including following steps: using zirconium niobium alloy powder as raw material, conducting a 3D printing for one-piece molding to obtain an intermediate product of the uni-compartmental femoral condylar component, performing hot isostatic pressing and cryogenic oxidation to obtain the uni-compartmental femoral condylar component; the uni-compartmental femoral condylar component includes an articular surface and an osseointegration surface, a bone trabeculae is arranged on the osseointegration surface. The present invention can reduce the fretting wear of the interface between the prosthesis and the bone, and reduce the stress shielding effect of the prosthesis on the bone tissue, homogenize the stress of the femoral condylar bone tissue, and improve the initial stability and long-term stability of the uni-compartmental femoral condylar component.
