For all subjects, there was positive correlation between procedure time and anxiety (Spearman's rho 0.34; P=0.0002) and negative correlation between procedure time and overall satisfaction (Spearman's rho -0.23; P=0.01). Anxiety and satisfaction with perioperative updates were significantly improved by additional perioperative updates. These findings indicate that updating families during significant standardized strategic perioperative events can reduce the anxiety of loved ones and are preferred by most families.

The high cost of orthopaedic care has attracted criticism in the current value-based health care environment. The objective of this work was to assess the properties of a willingness to pay (WTP)-based approach to estimate the monetary value that patients place on health improvements in chronic knee conditions following orthopaedic treatment. A sample of patients with a chronic knee condition were surveyed between January and May of 2018 at a large orthopaedic practice. Each patient provided their WTP for restoration to ideal knee health and completed the Single Assessment Numerical Evaluation (SANE) to describe their baseline knee state. Average WTP was calculated for the total sample and stratified by income, age, and baseline SANE (for which 0 is the worst and 100 is the best) levels. The patient-perceived monetary value of each unit of SANE improvement was assessed. The study sample included 86 patients seeking orthopaedic care for a chronic knee condition. Mean baseline SANE score was 45.5 (standard deviation 25.0). Mean WTP to obtain i
