There have been many reports about surgical treatments of flexible flatfoot in children and acquired adult flatfoot deformity due to posterior tibial tendon dysfunction common in the 5th and 6th decades. However there has been a controversy for surgical treatment guideline for painful idiopathic flexible flatfoot deformities in young adults. Therefore, we present a 27-year-old female with severe painful idiopathic flexible flatfoot who was treated with medial sliding calcaneal osteotomy and subtalar arthroereisis using $Kalix^{(R)}$ (Newdeal SA, Vienne, France) endoprosthesis and had good clinical outcome with high patient satisfaction at 10 months follow-up postoperatively.

Purpose: The purpose of the study was to identify the subtypes of idiopathic osteoarthritis of the tarsometatarsal joints based on accompanying hindfoot, midfoot, or foot deformities and their corresponding surgical options and also to evaluate the overall clinical results. Materials and Methods: The study included 59 patients (67 feet) with idiopathic tarsometatarsal joint osteoarthritis. Tarsometatarsal fusion was performed for tarsometatarsal joint and accompanied secondary change was divided into subtypes and various bony reconstruction was carried out. The patients were evaluated with the AOFAS midfoot score and FFI. The average patient age was 60.2 years with 40.6 months follow-up. Fifty-four feet (80.6%) had been treated with realignment fusion. Twenty-six feet had first and second tarsometatarsal joint fusion, and 20 feet had first tarsometatarsal fusion only. Six subtypes were identified based on associated foot deformities: 1) in-situ without deformities (18%), 2) pes planovalgus (45%), 3) rockerbottom (15%), 4) cavus foot (1%), 5) hallux valgus (12%), and 6) hallux valgus with pes planovalgus or rockerbottom (9%). Plantar-medial closing-wedge resection was used in 10 feet to correct rockerbottom. For pes planovalgus, a medial sliding calcaneal osteotomy was done. Lateral column lengthening with medial sliding calcaneal osteotomy was done for severe pes planovalgus, and triple arthrodesis was done for rigid pes planovalgus. Hallux valgus was corrected with the Lapidus procedure (85.7%). Results: AOFAS midfoot scores improved from preoperative 34.1 points to postoperative 83.9 points (p<0.05). The Foot Function Index postoperatively also showed significant improvement (p<0.05), with a high satisfaction rate (86.6%). There were 29 complications, most commonly sesamoid pain. Conclusion: Idiopathic tarsometatarsal OA feet can be classified into six categories. Pes planovalgus feet should be treated with medial sliding calcaneal osteotomy, lateral column lengthening, or triple arthrodesis in addition to tarsometatarsal joint realignment fusion. Rockerbottom and hallux valgus deformities should also be addressed.

Purpose: To evaluate the clinical and radiographic results of surgical treatment for patients with sinus tarsi pain due to accessory talar facet impingement. Materials and Methods: Between July 2013 and July 2015, nine patients who underwent surgery for the accessory talar facet impingement were reviewed. The mean follow-up period was 18.6 months (12~36 months), and the mean age was 33.1 years (19~60 years). Previous trauma history, duration of symptom, and types of surgery were analyzed. The clinical results were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and visual analogue scale (VAS). Radiographic results were assessed using Meary's angle, calcaneal pitch angle, heel alignment angle, and heel alignment ratio. Results: All patients had evident trauma history prior to the initial symptom. The mean duration of symptoms was 25.6 months (6~120 months). Four patients received only accessory anterolateral talar facet (AALTF) excision, and four patients received medial sliding calcaneal osteotomy (MSCO). One patient underwent both AALTF excision and MSCO. The AOFAS ankle-hindfoot score was significantly improved from 73 (62~77) preoperatively to 93 (67~100) postoperatively. The VAS score was decreased from 6 (5~7) preoperatively to 1 (0~5) postoperatively. The Meary's angle and calcaneal pitch angle showed no significant difference after surgery. The heel alignment angle and ratio increased from $-3.6^{\circ}$ ($-10^{\circ}{\sim}5^{\circ}$) and 0.22 (-0.15~0.6) preoperatively to $2.8^{\circ}$ ($1^{\circ}{\sim}5^{\circ}$) and 0.42 (0.3~0.6) postoperatively, respectively. Conclusion: If there is persistent sinus tarsi pain in patients with hindfoot valgus, accessory talar facet impingement caused by AALTF could be considered as a cause of chronic sinus tarsi pain.
