Every month, JBJS publishes a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 13 subspecialties. Click here for a collection of OrthoBuzz summaries of these “What’s New” articles. This month, Matthew R. Schmitz, MD, JBJS Deputy Editor for Social Media, selected the 5 most clinically compelling findings from the >60 studies summarized in the May 20, 2020 “What’s New in Foot and Ankle Surgery.”
Total Ankle Replacement
—An analysis of a consecutive series of 278 total ankle replacemments1 found that the overall incidence of postoperative complications was 41.7%. However, the clinical outcome was affected in only 7.6% of these cases, as most complications were minor.
—A meta-analysis (total n = 397) found that functional outcomes and complications were similar after suture-button fixation and screw fixation for syndesmotic injuries.2 Time to full weight-bearing, however, was faster among patients receiving suture-button fixation.
Osteochondral Lesions of the Talus
—A prospective cohort study3 examined 101 patients with osteochondral talar lesions of <1.5 cm2. After a minimum follow-up of 36 months, patients treated with microfracture alone (n = 52) and patients treated with microfracture + autologous iliac crest bone marrow aspirate concentrate (BMAC) (n = 49) both reported significant improvement in pain, sport, and activities of daily living. The revision rate was significantly lower in the microfracture + BMAC cohort.
—A randomized controlled trial4 compared stretching alone (n = 20) with stretching + proximal medial gastrocnemius recession (n = 20) in patients with >12 months of plantar heel pain. The operative group had significantly greater improvements in functional and pain scores and in forefoot plantar pressure at 12 months of follow-up. Achilles function and calf weakness were similar in both groups.
—A retrospective case series reviewed 220 feet among 145 Nepalese children who had been treated for idiopathic clubfoot with the Ponseti method. At a minimum of 10 years of follow-up, 95% of the 220 feet achieved a plantigrade foot. Surgical treatment, typically a percutaneous Achilles tendon release, was required in 96% of the feet.
