Stability was similar after anatomic double-bundle ACLR in knees with differing amounts of hyperextension
By Monica Jaramillo
Recently published data showed that anatomic double-bundle ACL reconstruction in cases of extreme knee hypertension may result in postoperative rotational and anterior stability that is similar to that of cases of normal or mild knee hypertension. However, second-look arthroscopy results showed superficial laceration of the anteromedial bundle graft occurred in some of the cases in the patients with 10° or less or with more than 10° of hyperextension.
Kenichi Saito, MD, and colleagues 100 patients who underwent anatomic double-bundle ACL reconstruction with semitendinosus tendon grafts for any side-to-side difference (SSD) in anterior tibial translation. They patients underwent the pivot-shift test at 2 years postoperatively to measure their knee rotational stability. The mean follow-up was 28 months.
The investigators measured loss of extension (LOE) with lateral radiographs of the knees in full extension and they assessed graft integrity at 1 to 2 postoperative years postoperative via second-look arthroscopy.
