Minimal and Substantial Improvement Thresholds for Oxford Scores Following Primary Hip and Knee Replacement Based on Patient Satisfaction

The authors aimed to determine whether the Oxford Hip Score (OHS) and Oxford Knee Score (OKS) can effectively predict patient satisfaction following primary hip and knee replacements, and to establish thresholds for minimal clinically important difference (MCID) and substantial clinical benefit (SCB) to inform value-based healthcare policies. They identified specific postoperative score thresholds for both the OHS and OKS that could guide decision-making in clinical practice. The study found that preoperative scores were not reliable predictors of satisfaction, highlighting the importance of postoperative assessments.
