INTRODUCTION: The aim of this study is to assess what is the situation of those
patients who received a primary total knee arthroplasty or a revision knee
arthroplasty due to an arthritic genu valgum. MATERIAL & METHODS: We
performed a prospective study of 20 TKA and 20 revision knee arthroplasties
implanted as a result of arthritis with genu valgum, between 1997 and 2006, with a
median follow up of 7.5 years (range 12-4). We analyzed the survival of the implants,
the radiological situation prior to implant placement and during the follow up,
functional score using KSS and quality of life using the SF12 questionnaire.
RESULTS: Twenty TKA (18F; 2M) and twenty revision arthroplasties (17F; 2M) were
implanted in patients with a mean age of 72.24 and 72.55 respectively. One revision
arthroplasty was removed because of an infection. The mean score on the SF12 was
22 points for the primary and 20 for review. The correction of genu valgum achieved
with the revision arthroplasty was higher than that achieved if primary arthroplasty
was implanted. There were not varus or valgum deformities neither medial-lateral
instability in the physical examination of the primary arthroplasties. DISCUSSION:
Implantation of a primary TKA in patients with genu valgum is a procedure that
achieves good results and gets a good degree of patient satisfaction. Implantation of
a revision arthroplasty is justified in cases of very marked genu valgum, although a
more aggressive procedure with more bone resection, it gets equally satisfactory
results.
