POSTER ABSTRACTS - ISAKOS

Results: The mean follow-up time for assessment
for each of the 3 groups of patients were;
Unicondylar = 3.32 years, Primary = 5.30 years and
Revision = 5.06 years. The mean total WOMAC
scores for the 3 groups were; Unicondylar = 13.96,
Primary = 22.10, and Revision = 38.67. The
percentage of patients who underwent knee
arthroplasty that found it impossible to kneel
were; Unicondylar = 18%, Primary = 36% and
Revision = 66%. The commonest reasons why
patients found kneeling difficult were; pain and
stiffness around the knee prosthesis, fear of
harming the prosthesis and sensory deficit around
the knee. Visual Analogue Pain scores for
kneeling in the 3 patient groups were, Unicondylar
= 5.6, Primary = 7.12, Revision = 9.18. A minimum
of 30% of patients in each of the 3 groups reported
their daily lives were moderately-severely affected
due to their difficulty in kneeling following knee
arthroplasty. At least 60% of the patients in each
group reported they would like to have better
kneeling ability.
Conclusion: Unicondylar knee arthroplasty
patients have better WOMAC scores and find
kneeling easier than patients who have undergone
Primary knee arthroplasty (p
