Background:

Total knee replacement (TKR) is a common procedure for knee osteoarthritis.
Revision surgery for TKR remains a significant challenge, with rates up to 8.3%.
Minimizing bone resection during TKR is crucial for long-term implant survival and function.

Purpose of the Study:

To investigate if robotic-assisted TKR leads to reduced bone resection compared to conventional TKR.
To compare bone cut measurements between robotic and conventional TKR procedures.
To evaluate the utilization of tibial polyethylene insert sizes in robotic TKR.

Main Methods:

Retrospective analysis of 157 primary TKRs performed by a single surgeon.
Examination of tibial polyethylene inserts and bone cuts.
Comparison of bone resection volumes between robotic and conventional TKR groups.

Main Results:

93.3% of robotic TKR cases used the 9 mm base size tibial polyethylene insert.
Average distal femoral cut was 7.4 mm, with a minimum of 3 mm.
Average tibial cut was 6.4 mm.

Conclusions:

Robotic TKR appears to reduce bone resection compared to conventional TKR.
The findings suggest potential benefits of robotic assistance in bone preservation during TKR.
Further research is warranted to confirm these findings and explore clinical implications.
