Post-Operative Patient Preference of Knee in Cruciate Retaining Vs Posterior Stabilized in Bilateral Total Knee Arthroplasty - A Long Term Prospective Follow Up Study

Patient satisfaction after Total Knee Arthroplasty (TKA) is a matter of concern. There is multitude of patient, surgery and implant factors associated to it. Implant design is one of the important factors. Here, we try to assess the correlation between the implant design [Cruciate Retaining (CR) or Posterior Stabilising (PS)] and the patient's preference of satisfaction in patients undergoing Bilateral Total Knee Arthroplasty for equally affected arthritic knees. 34 patients (68 knees) were followed up for a period of 2 years and Knee Society Knee Scoring (KSKS), preference data were recorded and statistically assessed. Correlation between implant designs were also looked into. At 6 weeks, 3 months, 6 months, 1 year and 2 years follow up, there is significant association of side preference to the side which was operated first irrespective of the implant design. There was no association between the implant design (CR, PS) to the side preference. Patient showed a strong association of pain scoring to side preference. We would like to follow up this finding with more number of samples.
