Introduction
Total hip and knee arthroplasty (THA/TKA) are among the most successful
orthopedic operations performed, aiming at the alleviation of
osteoarthritic pain. This report is a surface topography study that
assesses the mechanism by which THA or TKA influences truncal
parameters. This study represents the first time that surface topography
has been used for the assessment of truncal parameters.
Methods
In total, 15 patients with THA, including nine women and six men, with a
mean age of 65.07 +/- 9.73 years (range: 47-80 years), and 23 patients
with TKA were assessed preoperatively and four and 12 months
postoperatively. These patients were also compared with a control group
(CG) that included 25 individuals, including 12 women and 13 men, with a
mean age of 69.28 +/- 10.11 years (range: 55-86 years). The Diers
Formetric four-D analysis system was used to calculate several truncal
parameters in all planes.
Results
Data analysis revealed statistically significant differences in the
kyphotic angle (degrees; 56.50 -> 63.57, p < 0.05) and the pelvic
obliquity (degrees; 3.40 -> 1.93, p < 0.05) between measurements at
baseline and 12 months after THA. Statistically significant differences
were noted for the pelvic obliquity (degrees; 2.74 -> 1.43, p < 0.05)
between measurements at baseline and 12 months after TKA.
Conclusions
THA and TKA are causes of truncal morphological alterations. THA and TKA
improved pelvic obliquity, contributing to correct the posture in the
patients.
