PATIENT OUTCOMES IN PRIMARY AND REVISION KNEE REPLACEMENT. A PROSPECTIVE STUDY

There has been speculation as to whether the outcome of revision total knee arthroplasty (TKA) is as successful as primary TKA. The purpose of this study was to assess patient outcomes following revision TKA and compare them to patient outcomes following primary TKA.

This study collected data prospectively from patients operated upon by one surgeon using one prosthesis in each group. Patients completed SF12 and WOMAC questionnaires pre-operatively and at six and twelve months post-operatively. In the primary TKA group there were 84 patients. In the revision TKA group there were 60 patients. Statistical analysis was performed using paired and unpaired t-tests.

Results showed that the improvements in SF12 physical scores and WOMAC pain, stiffness and function scores in both primary TKA and revision TKA patients were statistically significant (p < 0.0001). There was no significant difference in the magnitude of the improvement in SF12 physical (p = 0.7145) and WOMAC pain (p = 0.0902), stiffness (p = 0.1557) and function (p = 0.3152) scores between the primary and revision patients following surgery.

The mental scores of patients in both groups showed no significant difference following surgery (Primary p = 0.823, Revision p = 0.7095).

The findings show that primary and revision TKA lead to a comparable improvement in patient perceived outcomes of physical health parameters.

However, there is no significant improvement in patient perception of mental health.
