Cementation technique yielded balance-related variability in TKA
Recently published results showed a significant amount of balance-related variability was contributed by the cementation technique during the fixation stage of total knee arthroplasty.
Researchers confirmed quantifiably balanced joints in 93 patients who underwent sensor-assisted total knee arthroplasty (TKA) prior to cementation. Researchers reinserted the sensor into the joint after cementing and final component placement to capture any cementation-induced changes in loading.
Results showed 44% of patients experienced imbalance after cementation. Researchers noted neither surgeon experience, cement type nor knee system led to a difference in the proportion of imbalance knees. Researchers also found increased loading in the medial compartment among most of the knees. – by Casey Tingle
