Abstract

Abstract : Objective: The purpose of this study was to evaluate the effects of low-intensity pulsed ultrasound (LIPUS) on bone healing at osteotomy sites after open wedge high tibial osteotomy (OWHTO). Materials and Methods: Fifty-four patients underwent OWHTO without bone grafting. Twenty-seven cases treated with LIPUS (group L) after surgery were compared with 27 cases without LIPUS treatment (group C). We divided the osteotomy gap into the lateral hinge and 4 zones on anteroposterior radiography, and the progression of gap filling was evaluated at 1, 3, and 6 months post-operatively in both groups. Results: In group L, the lateral hinge formed a union at 3 months postoperatively in 23 knees (85.2%). At 6 months, gap filling in 17 knees (63%) reached to zone 2. In group C, while the lateral hinge formed a union at 3 months postoperatively in 24 knees (88.9%). At 6 months, gap filling in 14 knees (51.9%) reached to zone 2. The progression of gap filling were 6.5%, 15.7%, and 29.1% (at 1, 3, and 6 months after surgery, respectively) in group L, while the progress levels at the same time points were 6.9%, 16.4%, and 27.3% in group C. There were no significant differences between the 2 groups. Discussion: LIPUS did not accelerate bone healing after OWHTO.
