Aims of the study: a) To compare the functional outcomes in patients with highflexion
and standard posterior stabilized total knee replacement. b) To compare our
results with previous published literature. Materials & methods: We studied thirty
knees that had a total knee arthroplasty with a high-flexion design and thirty that had
a total knee arthroplasty with a standard design over a period of 3yrs between
January 2005 to December 2007 at HOSMAT hospital, Bangalore, and were followed
prospectively for a minimum of two years. The arc of maximal non-weight-bearing
passive flexion was measured. In addition, the functional outcomes in these two
groups were assessed with use of the Hospital for Special Surgery and WOMAC
Score system. Results: At the time of the final follow-up, the average maximal nonweight-bearing
flexion was 129.3* for the knees in the high-flexion group and
130.3*for the knees in the standard group; the difference was not significant. The
average Hospital for Special Surgery knee score was 94.4 points in the high-flexion
group and 92.4 points in the standard group; the difference was not significant. The
Western Ontario and McMaster Universities Osteoarthritis Index scores also showed
no significant difference between the groups.Conclusions: For knees managed with a
posterior stabilized total knee arthroplasty, those that had the high-flexion design and
those that had the standard design were found to have a similar range of motion.
Moreover, no significant difference was found in terms of the other functional
outcomes examined.
