Follow-up occurred 1, 3, 6, and 12 months postoperatively and yearly thereafter.

The incidences of orthopedic complications were 10% in the PFNA to CTHA group and 19.3% in the PFNA to UTHA group (P = .040). Significant differences were also observed regarding the incidence of prosthesis revision (1.7% for PFNA to CTHA vs 7.2% for PFNA to UTHA, P = .036). From the three years after conversion surgery to the final follow-up, significant differences were detected in HHS between groups (each P &lt; .05). At the final follow-up, a statistically significant difference was detected in the HHS (79.54\u00b118.85 for PFNA to CTHA vs. 75.26\u00b118.27 for PFNA to UTHA, P = .014).<\/jats:p>\n
