Objective:The follow-up period before implementing a new concept or technique
introduced in a clinical study generally takes a long period. The present study is an
attempt to shorten the follow-up period. A prospective study with measuring dynamic
reaction force of feet to monitor the relationship between the clinical outcome and
gait function in TKA patients following slightly valgus overcorrection was conducted.
Theoretically, slightly valgus overcorrection for patients who underwent TKA might
achieve more benefits.Methods: A device of the Dynamic Foot Pressure Assessment Unit (DFPAU), which
was revised from the Computer Dyno Graphy (CDG), was used to investigate the
clinical outcome in patients with unilateral total knee arthroplasty. Thirty-eight knees
were overcorrected with slight valgus position (3° on the mechanical axis) and
regularly followed for at least 1 year. Evaluation of gait analysis with the described
device was performed preoperatively, before discharge, 1 month, 3 months, and 1
year postoperatively.
Results: At 1 year, the ratio of force for single leg stance (RFL) and the ratio of
impulse for single leg stance (RIL) had significant improvement as compared with the
preoperative status. The improvements even reached normal levels as compared with
the contralateral knee. In addition, the Knee Society (KS) functional scores also
showed significant improvement as compared with the preoperative status (86 versus
52 points). The optimal height of the handgrip of a walker was found to be at the level
of the wrist crease when the upper extremity hung down.
Conclusions: Assessment of dynamic reaction force of feet might be used to monitor
the outcomes of clinical treatment. |
