A few studies have reported satisfactory results in stages I and II posterior tibial tendon dysfunction (Johnson and Strom classification). This approach allows us to assess the posterior tibial tendon and the spring ligament status, and if needed to perform a synovectomy with soft-tissue debridement. Longitudinal split tendon tears can also be repaired. In case of failure, a traditional corrective open surgery can normally be performed. In this manuscript, we summarize the history of this technique and also reported the indications, surgical approach, results, and complications. Copyright © 2020 Wolters Kluwer Health, Inc.
