RESUMO
We performed a retrospective study of the radiographic position of femoral and tibial components in a series of revision total knee arthroplasties using diaphyseal-engaging, press fit, modular stems. Fifty-two consecutive revision cases were performed. Femoral and tibial component alignment was measured preoperatively and postoperatively. The canal-filling ratio was measured and correlated with anatomic alignment. There was a trend toward improved alignment with increasing canal fill, suggesting that uncemented diaphyseal engaging press-fit modular stems facilitate accurate alignment for both femoral and tibial components in revision surgery.

The purpose of the current study was to determine the usefulness of erythrocyte sedimentation rate and C-reactive protein in pediatric bone and joint infections treated with and without surgery. The medical records of 50 patients admitted for acute osteomyelitis, septic arthritis, or both were reviewed retrospectively. There were 22 patients with septic arthritis, 20 with osteomyelitis, and eight with osteomyelitis with adjacent septic arthritis. There were 25 patients each in the surgical and nonsurgical groups. There was a statistically significant difference between the two groups regarding mean days to peak and normalization of erythrocyte sedimentation rate values and normalization of C-reactive protein values. Statistically significant differences were revealed for the mean days to normalization of erythrocyte sedimentation rate and C-reactive protein values among the patients with a diagnosis of osteomyelitis, septic arthritis, or both. The mean days to peak and normalization for erythrocyte sedimentation rate and C-reactive protein were twice as long in the surgical group as compared with the nonsurgical group. Complete recovery was achieved by all patients. This information should help the clinician in the diagnosis and treatment of children having surgery for acute osteomyelitis and septic arthritis.
