摘要：

Background: The use of computer assisted joint replacement has facilitated precise intra-operative measurement of knee kinematics. The changes in "screw home mechanism" (SHM) resulting from Total Knee Arthroplasty (TKA) with different prostheses and constraints has not yet been accurately described. Methods: A pilot study was first completed. Intraoperative kinematic data was collected two groups of 15 patients receiving different prostheses. Results: On average, patients lost 5.3 degrees of ER (SD = 6.1 degrees). There was no significant difference between the prostheses or different prosthetic constraints. Conclusions: There significant loss of SHM after TKA. Further research is required to understand its impact on patient function.
