Inter- and Intraobserver Reliability of the COFAS End-Stage Ankle Arthritis Classification System

Abstract

The COFAS classification system appears to be a valid tool for the management and research of end-stage ankle arthritis.

Isolated Talonavicular Fusion With Tension Band for Müller-Weiss Syndrome

“…The mean change was 0.7 ± 7.3 degrees (95% CI, -4.5, 5.9; P = .77). The calcaneal pitch improved from preoperatively 10.3 ± 5.7 (range, [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] degrees to 14.7 ± 4.5 (range, [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] degrees postoperatively. The significant mean increase was 4.4 ± 2.7 degrees (95% CI, 2.5, 6.3; P = .0006).…”

Intermediate-Term Results of Total Ankle Replacement and Ankle Arthrodesis

“…In the linear mixed-effects regression model, adjustments were made for patient age, sex, operatively treated side, smoking status, BMI, inflammatory arthritis diagnosis, and baseline score to minimize potential bias, and these adjustments resulted in a substantial attenuation of the difference between the final AOS scores in the arthrodesis and ankle replacement groups. Another limitation of this study is the fact that we did not differentiate among implant types, etiologies leading to surgery, or preoperative or intraoperative COFAS classifications 7,22 . Designation of cohorts according to these variables may be a consideration for future studies.…”

The outcome of the Mobility total ankle replacement at a mean of four years

“…These images and the operative findings were used to establish the Canadian Orthopaedic Foot and Ankle Society (COFAS) score. 17 The Cedara I-Reach 4.4 program (Cedara Software Corporation, Mississauga, Canada) was used for assessment of post-operative weight-bearing radiographs, which included analysis of the following features on AP and mortise radiographs: 1) alignment of the tibial component (Fig. 1a); 2) displacement of the talar component relative to the tibial component in the coronal plane (Fig.…”
