Background:
The literature lacks studies providing long- term patient-re-
ported, functional and radiological outcomes on patients with patella fractures
treated with modern treatment modalities.
Purpose / Aim of Study:
The primary aim was to investigate the long- term
health-related quality of life (HRQOL) in adult patients treated for traumatic
patella fractures. The explorative aim was to report the associations between
HRQOL and knee osteoarthritis, muscle strength and gait function.
Materials and Methods:
The study was designed as a cohort study. All patients
treated for patella fractures at Aalborg University Hospital between January
2006 and December 2009 were identified. Patients between 18 and 80 years
were considered for inclusion. All fractures were either treated with splinting
or open reduction and internal fixation. Data were collected by retrospective
chart review and clinical examination of patients.
The main outcome measure
for HRQOL was the EQ5D-5L index score. The classifications by Sperner and
Kellgren/Lawrence were applied to evaluate osteoarthritis. Knee and associated
knee problems were evaluated with KOOS. Muscle strength was measured with
a dynamometer. Gait was analyzed using a pressure-sensitive mat.
Findings / Results:
49 patients were included with a mean follow-up time of
8.5 years (range 7-10) and a mean age of 53.9 years. The mean EQ5D-5L index
value was 0.741 (95% CI 0.675-0.807), being significantly worse compared to
an established reference population. Knee osteoarthritis, muscle strength and
gait patterns were not associated with HRQOL, except for gait speed, which
was found to have a weak positive correlation to HRQOL (P=0.03).
Conclusions:
At 8.5 years following a patella fracture, HRQOL was significantly
worse compared to an age-matched reference population.
