Gait biomechanics in patients with medial knee osteoarthritis were significantly improved 5 years after concomitant high tibial osteotomy and anterior cruciate ligament reconstruction, according to a prospective cohort study conducted by Kendal Marriott and associates.
In the 33 patients who underwent the dual surgeries, three-dimensional gait analysis showed that the peak knee adduction moment had decreased significantly in the surgical limb 5 years after surgery, compared with a nonsignificant increase in the nonsurgical limb. A significant decrease in the peak knee flexion moment was seen in both the surgical and nonsurgical limbs. Progress plateaued 2-5 years post surgery, but improvements gained were maintained at the 5-year postsurgery mark.
As concomitant high tibial osteotomy and anterior cruciate ligament reconstruction is relatively rare, “longer term follow-up and comparisons with other treatment strategies are both warranted and required to better evaluate the clinical effect of this seemingly biomechanically efficacious procedure,” the investigators concluded.
