Figure 2: Graphic visualization of the neural network output illustrating the three-layer perceptron decision areas, including the variables pain intensity,<br />
Kellgren and Lawrence grades, WOMAC total score, use of medication (for pain, aching, or stiffness in the knee), and body mass index into the neural<br />
network. Areas represent: green area = no TKA within next 2 years, red area = TKA within next 2 years, and grey area = no prediction is made (1).<br />
Results and Conclusion<br />
Concludingly, our results indicate that significant worsening of pain, function,<br />
and quality of life in the year prior to the TKA seems to be the more dominant<br />
decision driving factor as compared to the radiographic structural changes<br />
of the knee. Furthermore, we were able to establish a model that correctly<br />
predicted 80% of the classified individuals to undergo TKA surgery within the<br />
next 2 years, with a positive predictive value of 84%, and a negative predictive<br />
value of 73% 1 . Our model is based on easily accessible patient data,<br />
making it easily applicable in a primary care setting to evaluate the need for<br />
TKA surgery within the next two years and to give the patient an idea about<br />
their status quo.<br />
