Abstract
Aim: The aim of the present retrospective matched pair study was
to compare the clinical results of patients undergoing total knee
arthroplasty (TKA) with two different operation strategies: tibia first
vs. Femur first for ligament balancing and rotational alignment of
the femoral compoment.
Methods: In this study 30 patients underwent TKA with the fixed
bearing prosthesis Innex FIXUC between 2003 and 2005. In the
same period of time the posterior stabilized prosthesis NexGen
LPS was implanted in 123 patients. Out of these, 30 patients were
matched to the 30 patients of the Innex group based on
parameters age, gender, height, weight and BMI. All implants were
cemented. Clinical examination was rated using UCLA score, Knee
Society Score, Lequesne score for knees, a visual analogue scale
(VAS) for pain and the Feller patellar score. Three patients in the
Innex group were lost to follow-up, and 27 matched pairs could
finally be analysed.
Results: At a mean follow up of 25 months (Innex) and 3 years
(NexGen) statistically significant differences (p < 0.05) with
advantages for the NexGen were found in the UCLA activity score
(4.9 vs. 5.9,p = 0.013), in part A (knee score) of the Knee Society
Score (78.9 vs. 91.0, p = 0.002) as well as the total score (153.9
vs. 173.2, p = 0.012), VAS (2.1 vs. 0.6, p = 0.003) and in the
Lequesne score knee (5.7 vs. 3.6, p = 0.024). No statistically
significant differences (p < 0.05) were found in the function score
of the Knee Society Score and the patellar score (Feller).
Conclusion: In the described setting there were functional
advantages for the NexGen prosthesis (Femur first) at a
comparable revision rate. However, satisfactory results with the
Innex FIXUC are possible, too.
