This study compares CoCrMo particles generated by a high-energy ball milling method with those produced the established Buchhorn and in vivo-generated wear from periprosthetic tissue. were utilization both methods. The particle size distribution was analyzed using laser diffraction, morphology examined through scanning electron microscopy (SEM). Energy-dispersive X-ray spectroscopy (EDS) provided qualitative analysis of material composition. yielded D50 7.92 µm, significantly smaller value than 88.30 µm observed for particles. SEM demonstrated that mill have roundish, red blood cell-like irregular shape, similar to vivo. In contrast, exhibited flake-like morphology. displayed tendency towards agglomeration, which also conclusion, produces closely resemble natural terms These provide superior model biological testing comparison method. Furthermore, offers advantages reproducibility scalability, making it promising alternative generation orthopedic research.
