High tibial osteotomy (HTO) is a widely accepted and performed procedure to treat medial knee arthrosis. The aim of this review is to evaluate the different surgical options in medial knee arthrosis, focusing on indications, patient's selection, long-term follow-up and survival analysis of HTO. Comparison and pooling of results are challenging because of different evaluation systems, small cohort number, and different surgical techniques. No differences have been described between opening and closing wedged HTO in terms of outcomes. Excellent early survivorship and good clinical outcomes were reported also with concomitant procedures. Correct indications, preoperative workup/planning, and technique selection are essential in achieving good results. The choice between opening and closing wedge osteotomy, graft selection in opening wedge HTO, comparison between HTO and unicompartmental knee arthroplasty, and the results of revised HTO to total knee replacement are currently under debate and will be discussed in the present review.
Overall, good outcomes and survivorship (77% at 108 months) were obtained in this case series. However, 25.6% of the patients would not undergo the surgery again. Increased age, increased femoral anteversion, foot pronation, and postoperative patellofemoral crepitus were identified as negative prognostic factors.
Purpose. The aim was to evaluate and compare patient's health-related quality of life after THA for osteoarthritis and femoral neck fracture. The postoperative outcome was retrospectively evaluated in patients who underwent THA with an intracapsular femoral neck fracture (Group A) or with an hip osteoarthritis (Group B). Methods. Length discrepancy was measured on postoperative X-rays. Study groups were compared as to age, results of WOMAC and SF-36 tests, limb length discrepancy (LLD) by independent group t-test. Correlations between LLD and results obtained atWOMAC test were performed. 117 patients were enrolled. The 2 groups were similar as to age, type of implanted stem and sex. Mean follow up was 2,4 years for group A and 2,3 years for group B. Results. WOMAC score was found higher in group A in all items examinated. Correlation tests did not indicate a statistically significant linear relationship between LLD and WOMAC score in both groups. Conclusions. Patients who received THA for arthritis have better perception of quality of life than traumatologic patients. Although LLD should always be strongly considered by the surgeons performing a THA, LLD alone can't be considered as an indicator of patient dissatisfaction or clinical bad result after a 2-year followup.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
