Evaluation of the Intact Anterior Talofibular and Calcaneofibular Ligaments, Injuries, and Repairs With and Without Augmentation: A Biomechanical Robotic Study.

Background: Acute ankle sprains are common injuries. The anterior talofibular (ATFL) and calcaneofibular ligaments (CFL) are the most injured lateral structures. However, controversy exists on the optimal surgical treatment when the injury is both acute and severe or becomes chronic and unstable.

Locked Dorsal Compression Plate Arthrodesis for Degenerative Arthritis of the Midfoot.

Midfoot arthrodesis is the accepted surgical treatment for symptomatic midfoot arthritis. The published literature has focused on joint-spanning static fixation. Several companies have developed diamond-shaped locked dorsal compression plates, which allow for longitudinal joint compression.

Comparison of Single-Agent Versus 3-Additive Regional Anesthesia for Foot and Ankle Surgery.

Background: This study compared the results of regional blocks containing a single anesthetic, bupivacaine, with those containing bupivacaine and 3 additives (buprenorphine, clonidine, and dexamethasone) in patients undergoing foot and ankle surgery.

Methods: Eighty patients undergoing foot and ankle surgery over a 9-month period were prospectively enrolled and randomized to receive a peripheral nerve block containing either a single anesthetic (SA) or one with 3 additives (TA). Patients, surgeons, and anesthesiologists were blinded to the groups.

Cognition following computer-assisted total knee arthroplasty: a prospective cohort study.

Background: A substantial number of patients experience postoperative cognitive changes following total joint arthroplasty. The change in mental status may be the result of fat and bone-marrow-debris embolization. We hypothesized that the use of computer-assisted total knee arthroplasty, which does not involve the use of intramedullary alignment rods, would produce less fat and bone-marrow-debris embolization and, hence, fewer changes in mental status.
