Development of a Prediction Model to Estimate the Risk of Walking Limitations in Patients with Total Knee Arthroplasty

Abstract: A small but sizable proportion of patients with TKA had persistent mobility limitations. Our prediction model may help to risk-stratify patients, and external validation is required before the model can be used in clinical practice.

“…However, since strong statistically significant predictors were found, we can still draw important conclusions about how changes in the predictor values are associated with changes in the outcome. Those values are consistent with other studies attempting to explain the variability in outcome of TKR 13 , 22 , 23 and also with other well-known prediction tools such as QRISK and Framingham score that explain around 30% of the variability in outcome 37 .…”

“…The model is based on a predictor set that has limited overlap with the predictors used in the present study, and used data on postoperative recovery in addition to preoperative measurements. The predictive performance of their nomogram seems to be quite comparable to our model on walking limitations, with a reported c-statistic of 0.71 [11].…”

“…For effective expectation management, a prediction tool should ideally provide specific information on the most likely outcome on pain and function for an individual patient [6]. Pua et al [11] constructed a model on risk for walking limitations after TKA. In contrast to the models described in the previous paragraph that predict outcome in general, the model by Pua et al is the only predictive model for a specific functional outcome parameter available in literature.…”

“…As far as we know, no study has combined self-perceived questionnaires with a wide range of physical tests in a large population. Furthermore, no other study has objectively measured gait parameters in an extensive group of patients and used it in a prediction model [ 19 ]. This information is clinically relevant to determine the overall status of a patient.…”
