Category: Ankle; Arthroscopy; Sports Introduction/Purpose: This study evaluates the effects on functional outcomes of with or without calcaneofibular ligament reconstruction when reconstructing the ATFL for chronic lateral ankle instability Methods: This retrospective cohort study included 48 chronic lateral ankle instability patients with later ligament reconstruction that underwent either with or without a calcaneofibular ligament reconstruction using an ipsilateral free semitendinosus tendon autograft from June 2014 to October 2017. The Visual Analogue Scale score, the American Orthopaedic Foot & Ankle Society score, Karlsson Ankle Functional Score and Anterior Talar Translation in both groups were compared. Results: All patients were followed up for at a mean of 30 months, Visual Analogue Scale score, the American Orthopaedic Foot & Ankle Society score, Karlsson Ankle Functional Score and Anterior Talar Translation between two the groups were not statistically significant different. Conclusion: There are no differences at 2.5 years in postoperative ankle function and stability when an ipsilateral free semitendinosus tendon autograft is used to manage CLAI with anterior talofibular ligament reconstruction with and without reconstructing the calcaneofibular ligament.

Category: Ankle; Arthroscopy; Sports Introduction/Purpose: To evaluate the functional outcomes of arthroscopic anatomical reconstruction of anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) in the treatment of chronic lateral ankle instability with subtalar instability during short term follow-up Methods: We retrospectively analyzed data in 8 patients (5 males, 3 females; 2 left ankles, 6 right ankles) aged between 21 and 49 years, with an average age of 31.74 +- 8.48 years presenting with CLAI with subtalar instability from Auguse 2015 to October 2018. The duration of the symptoms lasted for 12 to 43 months, with an average of 24.26 +- 10.17 months. All patients underwent arthroscopic anatomical reconstruction of ATFL and CFL. Pre- and postoperative visual analogue scales (VAS), the American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Score (AOFAS) and the Karlsson Ankle Functional Score (KAFS) were compared to evaluate the curative effect of the operation Results: After surgery, all incisions healed in stage I and there were no complications. All patients were followed for 12 to 36 months, averaging 26.15 +- 9.34 months. At the final follow-up, the ankle varus stress test and ankle anterior drawer test were both negative. Range of joint motion was good. There was no lateral instability of the ankle and subtalar, and all patients returned to normal gait. The mean VAS score decreased to 1.06 +- 0.27, the AOFAS score increased to 93.16 +- 5.26 and the KAFS score increased to 92.01 +- 6.73. All the follow-up indexes were significantly different from those before surgery Conclusion: Arthroscopic anatomical reconstruction of ATFL and CFL in the treatment of chronic lateral ankle instability with subtalar instability is reliable in short term

Category: Arthroscopy; Sports; Trauma Introduction/Purpose: The purpose of this study was to evaluate the surgical technique and long-term clinical outcomes of all- inside arthroscopic treatment for large cystic osteochondral defect of the talus with the use of cancellous allograft. Methods: Eight patients admitted from January 2016 to October 2018 by our hospital for large cystic osteochondral defect of the talus was retrospectively analyzed with their complete follow-up data. The subjects consisted of 5 males and 3 females, aged between 27 to 50 years, and with an average age of 34.2 years. All of these cystic osteochondral defects were larger than 15 mm in diameter, sized 1.3cm3 to 5.2cm3. The visual analogue scale (VAS) score, American Orthopaedic Foot & Ankle Society (AOFAS) score, The Karlsson Ankle Functional Score (KAFS) and subjective satisfaction survey rating were obtained. CT scan and magnetic resonance imaging of the ankle were obtained before and after surgery. Results: All incisions were healed in the first stage, and no complications such as nerve, blood vessel and tendon injuries occurred. All patients were available for follow-up at a mean of 26.2 months (range, 18 to 48 months). By the last follow-up, the postoperatively AOFAS 、 KAFS scores were 86.5 and 84.2 compared with 60.8 and 59.3 preoperatively, respectively. And the mean VAS score decreased from 6.4 preoperatively to 1.1. The range of motion of the ankle joint was normal and returned to the pre-pain state for these patients. Six patients rated their result as excellent, 2 as good and none as fair. Conclusion: All-inside arthroscopic cancellous allograft was an effective option for the treatment of large cystic talus osteochondral defects.

Category: Lesser Toes Introduction/Purpose: To explore the surgical method of using the modified coughlin osteotomy for surgical treatment of high-grade tailor’s bunion and report the clinical outcomes Methods: From March 2013 to April 2015, the modified coughlin osteotomy was used for surgical treatment of high-grade tailor’s bunion. Twenty-two patients with 31 feet high-grade tailor’s bunion were hospitalized for treament in Xuzhou Central Hospital. There were 3 male (3 feet) and 19 female (28 feet) cases, aged 26 -78 years (mean 45.3y) old. The mean course of the painful bunionette disease was 6.7 years (range, 2 to 38 y). The average 4-5 intermetatarsal angle, fifth metatarsophalangeal angle and lateral deviation of the fifth metatarsal angle were 16.3°±5.1°, 10.7°±3.5° and 5.8°±2.6°, respectively. Main outcome measures included the 4-5 intermetatarsal angle, the fifth metatarsophalangeal angle, pain and appearance. Patients were scored using the American Orthopaedic Foot & Ankle Society (AOFAS) Lesser Toe Metatarsophalangeal-Interphalangeal Scale. Results: All operations were performed with no complications. Primarily healing of the wound was achieved in all cases. All the patients were followed up for a mean time of 17.8 months (range, 6 to 30 months). The mean fracture healing time was 11.6 weeks(range, 6 to 14 weeks), X-ray photograph proved fracture healing with a good positoin.All the patients had satisfactory appearance and sensory function witout callosum and metastatic metatarsalgiaat the final follow-up. The preoperatively average 4- 5 intermetatarsal angle, fifth metatarsophalangeal angle and lateral deviation of the fifth metatarsal angle were 5.9°±1.6°, 6.1°±2.3° and 2.2°±1.2°, respectively. The mean AOFAS score was 89.0±8.4. Conclusion: The modified coughlin osteotomy is a safe and easy treatment option for the high-grade tailor’s bunion deformity and provides patient satisfaction results

Category: Arthroscopy Introduction/Purpose: This study aim to investigate the clinical result of treating Tillaux-Chaput fractures using the all-inside ankle arthroscopy technique. Methods: We retrospectively evaluated 23 Tillaux-Chaput fractures patients who underwent all-inside ankle arthroscopy technique and were follow-up from May 2013 to June 2016. There were 15 males and 8 females, with the mean age of 30.4 years (range, 10-57 years). Right ankle was involved in 15 patients and left ankle in 8 patients. Eighteen patients had single Tillaux-Chaput fractures and 5 patients had combined proximal fibular fractures. While 20 cases were diagnosed by X-rays and 3 cases by CT. Ankle arthroscopy was used through the anterolateral and anteriormedal approaches for closed reduction and internal fixation using Herbert screw(s). The joints function was performed using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle hindfoot scale score. Results: Operative incisions of 23 cases were primary healing without complications of nerve, vessel and tendon injuries. The period of follow-up was 19.6 months (range, 12-25 months) and the time of Fracture union was 23.3 weeks (range, 12-36 weeks). At the time of last follow-up, none of the patients had any restriction in the ankle function and range of motion, with the ankle pain and weight-bearing walking pain. AOFAS score was changed from preoperative 53.3 points to 92.1 points, with the excellent-good rate of 100%. Conclusion: All-arthroscopy teatment by the anterolateral and anteriormedal approaches is a precise and effective method for closed reduction and internal fixation of Tillaux-Chaput fractures and deserves clinical application.
