Fig. 2From: Posterior condylar offset changes and its effect on clinical outcomes after posterior-substituting, fixed-bearing total knee arthroplasty: anterior versus posterior referencingProportional differences of the knees (%) between pre- and post-TKA based on the posterior condylar offset (PCO) and posterior condylar offset ratio (PCOR). The proportion of the preserved PCO (−2 mm < PCO difference ≤ 2 mm) was higher in the PR group than the AR group (p = 0.039)Back to article page
