The incidence of and risk factors for kinesiophobia after total knee arthroplasty (TKA) have not been well characterized in the literature. Thus, the aim of this study was to investigate the incidence of postoperative kinesiophobia among patients undergoing TKA and to identify the associated risk factors. ⋯ A 24.4% incidence rate of postoperative kinesiophobia was noted in patients following TKA. Older age (most notably ≥76 years old), lower education levels, negative coping styles, greater pain intensity, lower self-efficacy, and less social support were associated with odds of developing postoperative kinesiophobia.

The use of narcotics has been found to be a modifiable risk factor for success of arthroplasty. We sought to determine the risk factors leading to increased narcotic use after total hip arthroplasty and total knee arthroplasty. ⋯ This study suggests that a patient's preoperative narcotic, tramadol, benzodiazepine, and tobacco use are correlated to the amount of postoperative narcotic prescriptions filled in the 3 months following surgery. Predisposition to substance abuse may be a characteristic which leads to increased postoperative narcotic use.

The importance of medial compartment stability is recognized in total knee arthroplasty (TKA). To manage the medial extension-flexion gap, the posterior reference position can be changed from conventional posterior center to posterior medial in measured resection techniques. This study aimed to compare the intraoperative soft tissue balance and rotational kinematics between the posterior medial and posterior center reference groups. ⋯ The posterior reference position affects intraoperative kinematics and soft tissue balance in navigated PS TKA. Posterior medial reference PS TKA decreases the excessive tibial external rotation during midflexion and increases the flexion stability compared with conventional posterior center reference PS TKA.
