Differences in same vs. different surgeon performing conversion UKA to TKA
Introduction: Conversion surgery from UKA to TKA remains a challenge due to scarring, implant/cement removal, and loss of boney landmarks. Due to this challenge, conversion surgery may be best suited for a high volume or arthroplasty trained surgeon. The aim of this study is to identify if there are...

| description | Introduction: Conversion surgery from UKA to TKA remains a challenge due to scarring, implant/cement removal, and loss of boney landmarks. Due to this challenge, conversion surgery may be best suited for a high volume or arthroplasty trained surgeon. The aim of this study is to identify if there are differences in outcomes between the same and different surgeons performing UKA and conversion TKA. Methods: A retrospective chart review was performed on patients undergoing conversion UKA to TKA over a 10-year period at a single institution. Data extracted included surgical technique, reason for UKA failure, range of motion (ROM) at 1 year, need for augments and utilization of revision components. Results: 52 patients (53 knees) with a UKA converted to a TKA were divided into whether their conversion surgery was performed by the same (n = 19) or different surgeons (n = 34). There was no significant difference in complication rates (P = 0.255), MUA rates (P = 0.255), flexion (P = 0.812) or extension (P = 0.136) at one year post op. The use of augments in revision cases were higher for the same surgeon (P = 0.032) while the average poly size used was found to be significantly lower between the same surgeon performing the revision (P = 0.026). Conclusion: Conversion UKA to TKA by the same versus different surgeon's yield good results. This is likely in part due to experienced arthroplasty surgeons performing these conversion surgeries. However, there were differences in polyethene size and requirements in augments which suggests some differences in bony conservation and surgical technique between surgeons during conversion TKA. |
