A Retrospective Follow-Up Study of Satisfaction in Patients Undergoing Unicompartmental Knee Arthroplasty: A 3-Month Postoperative Analysis

Higher BMI, larger waist circumference, and greater subacute pain at one month are independent predictors of early dissatisfaction after UKA. Psychological factors, including preoperative anxiety, depression, and the lack of preventive pain psychological interventions, are also strongly associated with this outcome. Reducing postoperative pain, particularly at one month, enhances surgical outcome evaluations at this early time point. Clinicians should consider a multifactorial approach targeting these modifiable risk factors to improve satisfaction.
