JaiSLte N To find out the effect of sharp dissection compared to electrocautery for soft tissue
release and balancing in total knee replacement on proprioceptive sense, the study was carried
out as a parellel double blind trial with 2 year follow-up. There were 52 patients in the sharp
dissection group and 42 patients in the electrocautery group. Position sense of the operated
knees was evaluated by the ability to reproduce the same angles as the non operative knees
which acted as reference knees. The absolute different angles were used to evaluate the position
sense. Before the operation, the patients in both groups had similar biographic data, pathology,
and absolute different angles of knee positioning. After the operation, both groups had
improvement in knee position sense; however, the sharp dissection group had more rapid
improvement in the 1st post operative year. There was no significant difference at the 2 year follow-
up.
