Introduction
A critical question is the causal relationship between hip or knee
osteoarthritis (OA) and disordered spinal and pelvic morphology. The aim
of this study is to examine this correlation. Therefore, we studied the
effect of total hip or knee arthroplasty (THA/TKA) on truncal parameters
to determine the causal relationship between these two situations.
Materials and methods
This is a prospective study of the effect of THA or TKA in patients with
hip or knee OA on truncal morphological parameters. Patients with
one-sided hip or knee OA who chose to undergo THA or TKA were enrolled
and surveyed. A control group (CG) was also surveyed for comparison with
the patients. The patients were preoperatively examined for truncal
parameters using the Diers Formetric four-I) analysis system (surface
topography technique) to calculate several truncal parameters in all
planes at four months and 12 months postoperatively. Measurable
examinations were performed using the Statistical Package for the Social
Sciences (SPSS) version 17.00 (SPSS Inc., Chicago), and statistical
significance was set at a p-value of <0.05.
Results
The study examined 34 patients who underwent THA, including 19 women and
15 men with a mean age of 67.62 +/- 8.28 years. The study also examined
45 patients who underwent TKA, including 34 women and 11 men, with a
mean age of 72.42 +/- 7.0 years. These patients were also compared with
a CG that consisted of 25 normal individuals, including 12 women and 13
men, with a mean age of 69.28 +/- 10.11 years.
The results of this study from four months after THA revealed that the
lordotic angle, trunk torsion, pelvic inclination, pelvic obliquity, and
pelvis rotation were improved to normal levels. At 12 months after THA,
only the pelvic obliquity was improved to normal levels. At four months
after TKA the lordotic angle, pelvic inclination, and pelvic obliquity
were improved to normal levels. However, the fleche cervicale and
vertebral rotation were worse. At 12 months after TKA, only the pelvic
obliquity was improved to normal levels.
Conclusions
THA and TKA to correct hip and knee OA do not correct the disordered
morphology of the trunk in the long term. Thus, hip or knee OA does not
seem to be responsible for disordered trunk morphology. However, it
cannot be ruled out whether the disturbed morphology is responsible for
the appearance of the hip and knee OA.
