“The authors concluded that the data in this study confirm the importance of achieving and maintaining full and symmetric knee ROM, in order to lower the incidence of OA in the long term after surgery.”

“Poster presenter Dr. Urch said the take-home message is that “something as simple as symmetric ROM correlates very well with having normal radiographs at 10-year follow-up. Regardless of the status of the meniscus at the time of surgery, better motion—particularly extension—was associated with better radiographs long term. Motion is a simple but very important concept that often gets overlooked.”

Summary

  • This study found there was an association between range of motion and radiographic evidence of osteoarthritis after ACL reconstruction surgery.
  • Working on, achieving, and then maintaining full and equal range of motion between the two knees may help lower the chances of developing osteoarthritis long-term after surgery.
  • Regardless of the condition of the knee cartilage at the time of surgery, better motion, especially in extension, was associated with better long-term radiographs.

The 2011 Best Poster Award went to a prospective study examining the link between the loss of normal knee range of motion (ROM) after anterior cruciate ligament reconstruction (ACLR) and the incidence of arthritic changes observed on radiographs.

Poster 410, “Loss of knee motion after ACL reconstruction is associated with arthritic changes after surgery,” was authored by K. Donald Shelbourne, MD; Tinker Gray, MA, ELS; Heather Freeman, PT; and Scott E. Urch, MD. Article about the presentation written by Terry Stanton, the senior science writer for AAOS Now.

The radiographs taken: :45˚ posterior weight-bearing view bilateral symmetry, a basic body plan in which the left and right sides of the organism can be divided into approximate mirror images of each other along the midline, a view from the top of the knee, also called the merchants view, that is obtained within the vent 45° and with the x-ray beam directed through the knee from the head to the toe, and the lateral or bottom view which is taken from the side of the knee and shows the height of the patella in relation to the knee joint.
