Outcomes Following Revision Surgery After Failed Kidner Procedure for Painful Accessory Navicular
Abstract
BACKGROUND: The Kidner procedure is performed to treat painful accessory navicular syndrome, with varying results. Recurrent pain remains a complication, and to date, there is a paucity of literature regarding the causes of recurrent pain and surgical outcomes of revision.
METHODS: Twenty-one patients who underwent revision surgery for recurrent pain after the Kidner procedure were identified. All patients had their tendon inspected and treated, and all had a medial displacement calcaneal osteotomy. Revision was indicated after 6 months of failed conservative therapy. Pre- and postrevision radiographic measurements included lateral talo-first metatarsal angle (Meary's angle), talonavicular coverage angle, calcaneal pitch, and hindfoot moment arm (HMA). Meary's angle >4 degrees was considered a planus deformity and HMA >9.1 mm was considered a hindfoot valgus deformity; patients fulfilling both criteria were categorized as having planovalgus deformity. Measurements in the contralateral foot were performed to determine whether alignment of the involved side was attributed to failed treatment or a preexisting deformity. Visual analog scale and Foot and Ankle Outcome Scores were compared and average follow-up was 20.1 months (range, 14-26).
RESULTS: Preoperatively, 20 of 21 (95%) patients had a form of valgus heel alignment (planovalgus, n = 11; hindfoot valgus only, n = 9), and 1 had an isolated planus deformity. The contralateral side revealed similar deformity, with 17 of 21…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 13 participants or records.
