Level and Downhill Walking to Assess Implant Functionality in Bicruciate- and Posterior Cruciate-Retaining Total Knee Arthroplasty

Anterior cruciate ligament retention led to altered muscle recruitment during downhill walking in BiCR subjects compared with PCR subjects; thus, BiCR TKAs may offer some neuromuscular benefits for stabilizing the knee joint. In conclusion, level and downhill walking knee kinematics and kinetics combined with corresponding quadriceps and hamstrings EMG signals begin to build an overall picture of implant functionality.
