Abstract
The aim of this study was to determine whether body mass index and age had an
impact on functional recovery two years after total knee replacement. The research was conducted at
the Lovran Hospital of Orthopedics and Traumatology, School of Medicine, University of Rijeka,
Croatia. Study sample included patients who underwent total knee replacement surgery with median
parapatellar approach in 2019. Morphological measurements, knee range of motion and WOMAC
questionnaire score were examined before and two years after surgery. Descriptive statistics was used
for gender, age and body mass index, and inferential statistics was employed to check the correlation
of recovery measured by changes in the WOMAC score and change in the range of motion results
with age and body mass index. According to study results, male and female patients did not differ
in body mass index (t=1.184; p>0.05). There was no statistically significant correlation of functional
recovery of the patients with age (p=0.556), or between body mass index and differences in the range
of motion (p=0.927) from flexion to extension. The study indicated that knee arthroplasty and thus the
impact on functional recovery had an equally good effect regardless of age. In patients who had flexion
contracture before surgery, the surgery improved motion amplitude.
