Risk Assessment and Prediction Tool (RAPT) for Total Joint Arthroplasty (TJA)

Purpose: To evaluate a patient undergoing total joint arthroplasty (TJA) using the Risk Assessment and Prediction Tool (RAPT) of Oldmeadow et al.

Description

Oldmeadow et al developed the Risk Assessment and Prediction Tool (RAPT) to evaluate patients undergoing total joint arthroplasty. This can help to identify a patient who may require more aggressive management following surgery. The authors are from Austin and Repatriaton Medical Center in Victoria, Australia.


 

Patient selection: total hip or knee arthroplasty >= 50 years of age

 

Parameters:

(1) age in years

(2) gender

(3) walking distance

(4) use of gait aid

(5) use of community supports

(6) caregiver at home

total score =

= SUM(points for all 6 parameters)

 

Interpretation:

• minimum score: 1

• maximum score: 12

• The higher the score the more likely that the patient will be discharged home.
