Relationship between surgical balancing and outcome measures in total knees Lauren M. Chu, BS, Patrick A. Meere, MD, Cheongeun Oh, PhD, Peter S. Walker, PhD Arthroplasty Today DOI: 10.1016/j.artd.2019.01.001 Copyright © 2019 The Authors Terms and Conditions

Figure 1 The “smart knee fixture” used to determine the varus and valgus angles at the knee when a moment of 10 Nm was applied at the ankle. Arthroplasty Today DOI: (10.1016/j.artd.2019.01.001) Copyright © 2019 The Authors Terms and Conditions

Figure 2 The functional score at 1 year plotted against the deviation of the compartmental force ratio (CFR) from 0.5 (eg, A CFR of 0.4 and 0.6 have a deviation of 0.1). There was no correlation. Arthroplasty Today DOI: (10.1016/j.artd.2019.01.001) Copyright © 2019 The Authors Terms and Conditions

Figure 3 The functional score at 1 year plotted against the total contact force at surgery. There was no correlation. Arthroplasty Today DOI: (10.1016/j.artd.2019.01.001) Copyright © 2019 The Authors Terms and Conditions

Figure 4 The varus laxity angle plotted against the lateral contact force, and the valgus laxity angle plotted against the medial contact force. There was no correlation. Arthroplasty Today DOI: (10.1016/j.artd.2019.01.001) Copyright © 2019 The Authors Terms and Conditions
