Assessing patient-oriented results after revision total knee arthroplasty

Aseptic Revision Knee Arthroplasty With Total Stabilizer Prostheses Achieves Similar Functional Outcomes to Primary Total Knee Arthroplasty at 2 Years: A Longitudinal Cohort Study

“…In possibly, the most comprehensive article to date, Baker et al [3] report an analysis using data from the UK National Joint Registry and demonstrate revision cases to perform worse than primaries as assessed with patient-reported data (the OKS and satisfaction score) at 12 months. Lesser satisfaction is a typical report following revision surgery; Baier et al [15] reported a 28% complication rate and 26% reoperation rate in a series of 78 revision knees. Notably, these authors reported that 28% of patients would not have chosen revision surgery if they could "go back in time and decide again".…”

“…Mean changes in outcomes measures (between preop and 2 years postop) were: 15 Longitudinal changes in all 4 outcome measures were statistically significant at P < .001 (repeated measures ANOVA), highlighting the positive effect of revision arthroplasty on the patient's pain and physical function (Figs. 2-5).…”

Rotating hinge prosthesis for complex revision total knee arthroplasty: A review of the literature

“…having a 22% and Baier et al having a 28% complication rate. [23][24][25] However, Smith et al had a very high complication rate of 63% and Springer et al also had a high complication rate of 49% at the end of their study. 7,11…”

“…22 Baier et al indicated 45% of their rotating hinge cases due to aseptic loosening, if patients complained of weight-bearing pain or had osteolysis on serial radiographs. 23 Again, there was no statement in either study on why a rotating hinge was used instead of a less constrained device. Deehan et al indicated 24% of patients for ligamentous instability, while Smith et al and Joshi et al indicated 34% and 30% respectively.…”

Revision total knee arthroplasty

“…It is important to note that only 69% of all the patients reported overall satisfaction with the procedure. Baier et al 24 reported significant improvements in both the WOMAC and the Knee Society Score following revision TKA at an average follow-up of 81 mo in 78 patients. Ghanem et al 25 noted limitations of the Knee Society Score for assessing outcome after revision TKA and recommended the use of multiple outcomes measures for each patient to adequately reflect the true status of the TKA.…”
