INTERVENTIONAL
Conditions
Summary
the objective of the present study is to compare the post-operative laxity using stress radiographs and clinical scores in two groups of patients undergoing primary PS TKA with identical prosthetic model performed in two specialized centers, of which one group implanted with standard technique and one group through the intraoperative use of the tensioner
