In Vivo Kinematics for Subjects Implanted With Klassic Total Knee Arthroplasty (TKA)

2019-10-09 09:21:41 | BioPortfolio


In vivo knee kinematics will be assessed for 20 subjects that have been implanted with a Total Joint Orthopedics Klassic knee system by Dr. Aaron Hofmann of the Hofmann Arthritis Institute's Center for Precision Joint Replacement. This is the location from which all participants will be recruited and where fluoroscopy data collection will occur. Participants will undergo fluoroscopic surveillance of their implanted knee using a C-arm fluoroscopic unit while performing a deep knee bend activity at least six months post-operatively.


Enrollment will be increased to 24 subjects to ensure that researchers acquire the necessary 20 usable datasets for analysis and also to account for any subjects that may drop out of the study. There will be 12 subjects with the Klassic TKA in the right knee and 12 with the Klassic TKA in the left knee. At present, all TKA available for surgeons to use are asymmetric where there is a distinct femoral and tibial component for the left knee and a distinct femoral and tibial component for the right knee. The Klassic knee system is a symmetrical knee implant, where the same femoral and same tibial component can be used for either the right or left knee. The kinematics for the 10 left knees vs the 10 right knees will be compared. The results from this study will also be compared with previously published results for fluoroscopic studies assessing the in vivo kinematics during a deep knee bend that is available in the literature to determine if there is a difference.
