Our work

We have demonstrated that patient satisfaction following TKA is correlated with several preoperative variables including symptoms, pain, awareness of the knee and anxiety/depression.

The development of this new sensitive prediction tool for patient satisfaction following TKA may allow surgeons and patients to evaluate the risks and benefits of surgery on an individual basis. The predictive 10-question score will anticipate on 36 and 37% of the postoperative satisfaction at three months and 20 months with a sensitivity of 97% for both 3 months and 20 months. The specificity of this model is 75%.

Further research is necessary to confirm our findings at later postoperative intervals, and in other patient populations. This might help to answer the difficult question: “who is likely to benefit from TKA?”
