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.

In 2015, JBJS launched an “article exchange” collaboration with the Journal of Orthopaedic & Sports Physical Therapy (JOSPT) to support multidisciplinary integration, continuity of care, and excellent patient outcomes in orthopaedics and sports medicine.
During the month of July 2019, JBJS and OrthoBuzz readers will have open access to the JOSPT article titled “Effectiveness of Foot Orthoses Versus Corticosteroid Injection for Plantar Heel Pain: The SOOTHE Randomized Clinical Trial.”
Among 103 patients with plantar heel pain who received either arch-contouring foot orthoses or a single ultrasound-guided corticosteroid injection, the injection was more effective at week 4, but the foot orthoses were more effective at week 12. But the authors note that “the differences between the interventions did not meet the previously calculated minimal [clinically] important difference value of 12.5 points.”

This month, OrthoBuzz asked Sheldon Lin, MD, a co-author of the May 16, 2018 Specialty Update on Foot and Ankle Surgery, to select the five most clinically compelling findings from among the 60 studies cited in the article.
—A recent Level-I study1 investigated the efficacy of preemptive local anesthesia in combination with general or spinal anesthesia in 80 patients undergoing ankle arthroscopy. The authors found that patients receiving local anesthesia did not require any on-demand pain medication and reported lower pain intensity up to 24 hours post-arthroscopy. Patients in the spinal anesthesia-only group had better pain control than did patients receiving general anesthesia only.
—While arthrodesis of the first metatarsophalangeal (MTP) joint is the preferred treatment for this condition among most providers, concerns over medial column lengthening and degenerative changes at adjacent joints have led to continued interest in MTP arthroplasty. In a 15-year follow-up of 52 patients randomized to MTP joint arthrodesis or arthroplasty2, Stone et al. found that those who underwent arthrodesis had less pain, fewer revisions, and greater satisfaction than those in the arthroplasty group, with equal function scores. On the basis of these data, arthrodesis remains the treatment of choice for severe hallux rigidus.
Total Ankle Arthroplasty (TAA)
—In a prospective study of 451 patients with an average follow-up of 4.5 years, Lefrancois et al. compared clinical and functional outcomes of 4 TAA prostheses: the HINTEGRA implant, the Agility implant, the Mobility implant, and the Scandinavian Total Ankle Replacement (STAR). Patients with the Mobility implant had less improvement in scores on the Ankle Osteoarthritis Scale, while the other 3 implants had comparable results.
—In a matched cohort study of more than 3,000 patients examining the complication rates of TAA versus those of arthrodesis, Odum et al. found that patients undergoing arthrodesis had a 1.8-times higher risk of a major perioperative complication than those undergoing TAA.
—In a randomized controlled trial of 50 patients investigating the efficacy of botulinum toxin for treating plantar fasciitis3, Ahmad et al. found that patients in the botulinum toxin group had improved function and pain scores compared with the placebo group at 6 and 12 months post-injection, as well as a lower rate of surgical treatment for recalcitrant symptoms (0% versus 12%).
